00:00:00
In an increasingly interconnected world, the Internet of Things or IoT, is the
00:00:06
invisible force that merges our daily lives with technology, radically transforming the
00:00:12
way we interact with our environment. But what really is IoT? Let's imagine millions
00:00:20
of connected devices, machines and objects, exchanging information among themselves,
00:00:27
with us humans and with Artificial Intelligence entities, all through
00:00:33
the Internet. It is not just about transmitting and collecting data, but about converting
00:00:40
information into valuable knowledge, which drives intelligent decisions and transforms multiple
00:00:46
aspects of our daily lives. From smart homes to automated factories,
00:00:54
the IoT is redefining how we live, work and connect. It gives us control
00:01:00
over what previously seemed unattainable, optimizes processes that we thought were impossible to improve, and
00:01:07
helps us anticipate the unexpected. The IoT opens a horizon full of possibilities and opportunities.
00:01:17
Welcome to Works of Science... today we will explore the fascinating world of IoT! Hello, how are you?
00:01:30
I hope you are feeling very well! Welcome to the first Works of Science! program. First of all,
00:01:37
I introduce myself, my name is Javier Aira, by profession I am a Doctor in Computer Engineering
00:01:42
and I have worked for many years in different companies in the field of R&D, or Research
00:01:48
and Development. I am interested in the environment and caring for the planet, and I humbly believe that science
00:01:54
and technology can contribute a lot to these issues. The main objective of this channel
00:02:00
is scientific dissemination. In each program, we are going to present a technological discipline
00:02:06
and within that technological discipline, we are going to present five scientific works. We are going
00:02:11
to try to ensure that these scientific works can be explained in a simple,
00:02:16
simple way so that everyone understands it. We are going to leave the bibliographic sources and obviously I will
00:02:22
be available for all the questions you need. In this first program,
00:02:28
we are going to talk about the IoT, the Internet of Things or the Internet of Things (in English),
00:02:35
a multidisciplinary discipline that has been growing by leaps and bounds in recent years.
00:02:41
In this program, we are going to present five scientific works that I hope you like. First of all,
00:02:47
I apologize if there is any sloppiness in the editing of the audio or video, I promise
00:02:54
that over time we will improve these issues. But I won't bore you any more, let's start with the
00:02:59
program! In the first scientific research that we have to present to you today,
00:03:05
it is a work carried out by Doctor Fatma Talaat and a team from the
00:03:10
Kafrelsheikh University in Egypt. What this study does is carry out an analysis of the different
00:03:18
IoT sensors available, plus the different Artificial Intelligence techniques, specifically
00:03:24
Machine Learning to respond to this issue of detecting and monitoring stress in
00:03:29
people. It is a very complex work, very long, but it is super interesting. I hope you like it!
00:03:36
Stress is an inevitable part of our lives, but did you know that we could now monitor it
00:03:42
effectively using IoT technology and Artificial Intelligence? This study
00:03:49
has explored how wearable sensors and IoT and artificial intelligence techniques,
00:03:55
specifically Machine Learning, can monitor and detect
00:04:00
stress. The main goal is to develop a system that can automatically provide
00:04:07
prescriptions based on the patient's condition allowing doctors to monitor health
00:04:13
without the need for direct interaction. The study proposes a new stress monitoring algorithm
00:04:20
using wearable IoT sensors in synergy with Machine Learning. This project was established
00:04:27
in four main phases. Let's summarize it in a way so that we can all understand it:
00:04:33
the first phase called data acquisition consists of collecting data from
00:04:39
wearable devices such as bracelets and smart watches that measure parameters such as
00:04:45
heart rate, heart rate variability , or HRV, skin conductance
00:04:51
, temperature, among others. Phase two which is called data and signal processing,
00:04:58
The data from the devices is processed and peak enhancement of the signals is performed
00:05:04
using filtering and normalization techniques to eliminate noise and interference. In
00:05:11
the third phase, called prediction, the analysis and classification of the data is carried out using
00:05:17
certain Machine Learning algorithms such as Random Forest, the decision tree,
00:05:23
XGBoost and OSM Classifier. These algorithms were trained with labeled data to identify
00:05:31
patterns associated with stress levels. In the fourth phase, which is called model evaluation,
00:05:37
the performance evaluation of the models was carried out using grid search techniques
00:05:42
to optimize the hyperparameters and validate the accuracy of the system. Among the
00:05:48
Machine Learning algorithms evaluated, Random Forest proved to be the most suitable due to
00:05:54
its high precision and performance. The potential of this system is enormous, not only could it detect
00:06:01
conventional stress levels but it could also predict episodes of acute stress. This is
00:06:07
especially useful for people with chronic conditions who need constant monitoring. In
00:06:14
summary, stress monitoring using IoT and Artificial Intelligence represents a
00:06:21
significant advance in the field of digital health. It would allow us to manage our lives more effectively
00:06:27
and improve our quality of life. Well, I hope you liked this first
00:06:33
research work. Regarding the second, it is a very interesting one that has to do with the work of
00:06:39
Doctor Martin Wikelski. Doctor Wikelski is the director of the Max Planck Institute for Ornithology
00:06:46
in Germany. Dr. Wikelski is the pioneer in what is called the internet of animals,
00:06:52
playing with this IoT or the internet of things. It is about monitoring
00:06:57
animals from space. A fundamental tool to understand what is happening
00:07:03
with animals in the world, understand patterns of migration behavior
00:07:08
and different parameters that scientists are interested in and that can act accordingly
00:07:14
for their preservation. I hope you like it! Monitoring animals from space,
00:07:20
understanding their movements, their behaviors and how they interact with the world is no longer science
00:07:25
fiction, it is a reality. Thanks to the animal internet, it is a revolutionary concept
00:07:31
that has been led by Doctor Wikelski. Today I tell you about ICARUS, acronym for International
00:07:38
Cooperation for Animal Research Using Space, a pioneering project that uses space technology to
00:07:45
monitor animals in real time. This system connects animal behavior to technology
00:07:52
through satellites. They basically place small sensors on animals from migratory birds to
00:07:59
marine mammals to track their movements from anywhere on earth. The main objective
00:08:06
is to better understand their movement patterns and how these are linked to the environment
00:08:12
, helping to predict natural disasters, epidemics and climate change. This is where
00:08:19
the ICARUS project comes in. This project has put receivers into orbit on the
00:08:25
international space station, which connect with transmitters on animals. The transmitters are
00:08:31
tiny devices designed to be lightweight and animal-friendly, yet
00:08:38
powerful enough to send signals to the space station. These signals contain information
00:08:44
such as GPS location, body temperature, flight
00:08:50
or swimming behavior, and even the animals' acceleration. The most incredible thing is that all this information
00:08:56
is collected to create a global network allowing scientists and conservationists to
00:09:02
closely follow migratory species, understand their routes and how they respond to environmental changes. This
00:09:08
not only helps the conservation of endangered species, but also has applications
00:09:13
for predicting natural phenomena. The sensors used in the ICARUS project are designed
00:09:20
to be lightweight and long-lasting. The first prototypes were placed in birds
00:09:26
and its use has been extended to turtles, mammals and other animals. These sensors measure speed,
00:09:33
altitude, direction and other key data about animal behavior. Each of these teams,
00:09:39
They have advanced GPS and a long-lasting battery. Among the most notable conclusions
00:09:45
of the ICARUS project is the confirmation that animal movements can
00:09:51
give us critical clues about the state of our planet. With this project, it has been shown that
00:09:57
by monitoring animals from space, we can not only protect endangered species,
00:10:02
but also understand how their behavior is linked to the well-being of the planet. Well,
00:10:09
I hope you liked this work by Doctor Wikelski. Regarding the third,
00:10:14
I tell you that it is a research carried out by Doctor Alp Toymus and a team from
00:10:19
KOK University in Turkey. It has to do with the application of IoT in the medical context. Dr. Toymus
00:10:27
developed a system, or specifically an ultrasonic sensor, that allows measuring
00:10:32
bladder volume in people. This study is very novel. The study has shown
00:10:38
results that were very interesting and even some healthy people were used
00:10:44
to make the measurements. I hope you like it! Bladder volume monitoring is
00:10:50
crucial for early detection and management of lower urinary tract dysfunctions. Lower urinary tract dysfunction
00:10:57
affects millions of people annually worldwide and its
00:11:03
prevalence is increasing. Common causes include prostatic hyperplasia and
00:11:10
neurological disorders. Bladder catheterization is the most accurate method of measuring bladder volume,
00:11:18
but it is invasive and not suitable for routine examinations. Bladder ultrasound is a
00:11:24
non-invasive alternative, but does not allow continuous monitoring and requires
00:11:29
expensive equipment. More accurate and accessible technologies are needed for out-of-hospital monitoring
00:11:35
. The work of Doctor Alp Toymus presents a device that allows
00:11:41
continuous and autonomous monitoring of bladder volume with high precision. This is especially
00:11:47
useful for patients with lower urinary tract dysfunctions, as it provides
00:11:52
real-time data without the need for invasive procedures. Now, let's delve a little deeper
00:11:59
into the technical aspects of this device. It uses flexible ultrasonic transducers
00:12:05
that are supported by air, which significantly improves transducer sensitivity
00:12:11
and allows accurate measurements at low operating voltages. These translators adapt to
00:12:19
the shape of the body ensuring optimal contact and accurate measurement of bladder volume.
00:12:25
In addition, the very small control electronics allow the device to be compact
00:12:31
and portable. The wireless transmission capacity is another important aspect,
00:12:36
as it allows continuous and autonomous monitoring of bladder volume, without the need
00:12:42
for cables. To validate the proper functioning of the device, tests were carried out with
00:12:48
healthy volunteers with people selected based on the different shapes and sizes of their bladders.
00:12:56
The objective was to check if the device adapted to a wide variety of morphologies.
00:13:03
Volunteers wore the device continuously while bladder volume was measured
00:13:09
in real time. The data obtained was transmitted wirelessly to
00:13:15
be analyzed. These results were compared with traditional methods and it was shown that
00:13:22
the device has high precision, but with an advantage, being continuous and non-invasive.
00:13:29
In summary, the combination of flexible ultrasonic transducers, efficient and compact control electronics
00:13:36
, and wireless transmission capability make the device
00:13:42
a revolutionary tool in urinary health monitoring. Regarding
00:13:47
the fourth research work, I tell you that it is a project of my authorship.
00:13:53
It is a technological solution that I developed while at the University of Castilla La Mancha,
00:13:59
Albacete (Spain). It is a scientific work that I developed together with Teresa Olivares and Francisco
00:14:05
Delicate Martínez who were my thesis directors at that time. The project is called
00:14:12
SpectroGLY and is a comprehensive IoT solution that allows monitoring and detecting glyphosate in water.
00:14:18
Glyphosate is an agrochemical, specifically a herbicide that is used by agribusiness.
00:14:24
to eradicate undesirable weeds. Well, what this solution does is detect waste. This
00:14:31
agrochemical, based on hundreds of scientific works in the world, is showing its
00:14:39
consequences for both people's health and the environment in general. I hope you
00:14:44
like it. Glyphosate is the most widely used herbicide in the world and is used in
00:14:51
agribusiness to control weeds and increase productivity. However, its contamination
00:14:58
in water has become a serious health problem for people and the environment.
00:15:04
Detecting glyphosate in water is very complex since it requires expensive equipment,
00:15:10
highly trained personnel, and a laboratory environment. This is where SpectroGLY comes in. SpectroGLY is
00:15:18
a low-cost portable spectrometer capable of detecting glyphosate residues at
00:15:25
very low concentrations. Its main advantage is being compact and easy to use compared to
00:15:32
traditional equipment. This system integrates a digital traffic light to identify toxic concentration ranges
00:15:38
of glyphosate and quickly alert about water quality. At the core of SpectroGLY
00:15:45
is its multispectral sensor that measures the absorption of visible and near-infrared light
00:15:51
, thus allowing glyphosate to be accurately detected in just a few minutes. In addition, it includes
00:15:59
an LED shutter, like a flash, that allows samples to be homogenized. SpectroGLY incorporates
00:16:06
complementary sensors such as temperature, humidity and an accelerometer.
00:16:12
These sensors allow calculations to be adjusted precisely, depending on the operating context.
00:16:18
In terms of connectivity, SpectroGLY supports WiFi and LoRaWAN, which allows it to be used in
00:16:26
rural areas or cities. It also has a mobile application and an IoT platform in the cloud,
00:16:32
which allow you to monitor and analyze the results from anywhere in the world. In conclusion,
00:16:38
SpectroGLY has great potential to be a key tool to protect public health
00:16:44
and the environment, moving us closer to a safer future and providing
00:16:49
agile responses to water pollution. Well, we have reached the last
00:16:55
scientific work on today's program. Regarding this, I tell you that it is a research
00:17:00
carried out by Doctor Lei Hou and team at Teesside University, Middlesbrough,
00:17:06
United Kingdom. It is a novel autonomous wheelchair and an ecosystem of IoT sensors that provides
00:17:14
a response in the medical context to people who have mobility and health problems. At the same
00:17:20
time, it is an interesting and complex research work that we have to present to you now,
00:17:27
let's get to it! This project promises to significantly improve the quality of life of
00:17:33
people with reduced mobility. As I mentioned in the introduction to this work, it is
00:17:38
an autonomous wheelchair, combined with an advanced health monitoring system,
00:17:44
a clear example of how technology and innovation come together to transform lives. This
00:17:50
wheelchair is equipped with a series of very interesting technologies, first of all it has
00:17:56
a kit of sensors and actuators. It includes proximity sensors, cameras and LIDAR technology,
00:18:03
allowing the chair to detect obstacles and move safely. It also has
00:18:09
a motion controller. Thanks to this controller, information from the sensors
00:18:15
is processed in real time, allowing the chair to make intelligent decisions about direction
00:18:21
and speed. It also has a user interface, the best thing is its ease of use,
00:18:27
users can control it through a mobile app or simply using
00:18:33
voice commands. But that's not all, this chair also takes care of the health of the users, it has
00:18:40
biometric sensors that constantly measure vital signs such as heart rate,
00:18:45
blood pressure and blood oxygen levels. It also has IoT connectivity, since
00:18:53
all this information is processed and sent in real time to the cloud, where health professionals
00:18:59
can analyze the data. There is also an alert and notification system if something
00:19:07
out of the ordinary is detected. The system sends alerts to both the user, doctor and
00:19:13
caregivers, which adds an extra layer of security. Now, how does all this work?
00:19:22
I'm going to try to summarize it and break it down into three main aspects; The first
00:19:29
has to do with autonomous navigation with the help of artificial intelligence algorithms,
00:19:35
the chair maps the environment, plans safe routes and avoids obstacles in real time, another large block
00:19:44
has to do with the processing of health data, biometric sensors collect data that,
00:19:50
through automatic learning or Machine Learning, detects patterns and possible health problems.
00:19:57
All this is stored in the cloud and accessible from anywhere in the world! Another big block
00:20:03
has to do with security and privacy. Data protection is essential,
00:20:09
so everything is encrypted and only accessible by authorized people. In summary, this project
00:20:16
not only stands out for its innovation, but for the real impact it can have on the lives of many
00:20:22
people, another example of how technology can improve the quality of our lives.
00:20:29
Well, we have reached the end of the first WoS [Works of Science] program. I hope you liked the
00:20:33
content and scientific research we present! In the description
00:20:39
of the video I am going to leave you the bibliographical references, a URL and an introduction to
00:20:44
each of the works we present. On the other hand, if you have any questions or comments,

00:21:02
this video if you found it interesting and I will see you in the next program, which we are going to talk about
00:21:08
Artificial Intelligence, where we are also going to present five scientific works. Well,
00:21:13
