Dear reader, have you ever heard about the generation of electricity from the human body, yes I knew.. The first thing that came to your mind now is the science fiction films in which the hero used to extract electrical charges from his body, for you this may be just a science fiction that does not affect reality in any way. Relevancy But I am pleased to inform you that this fantasy can be real with the technological advances that our time is witnessing now. I present to you the relationship of electricity to the human body and some modern technologies that depend on generating electricity from the human body.
The importance of electricity in the human body .
Without electricity, The human being could not do anything, because your mind and heart will never work. The common communication between humans is done by the electricity generated within their bodies. Here comes the question, how are those electrical signals transmitted? You may say through the behavior of electricity and for you that answer is motivated by a joke!!
But already electrical signals travel through vital electrical cables. These cables are known as nerves, and they are part of our nervous system that extends from the brain and spinal cord to all parts of the body.
The relationship of the nervous system with electricity
The nervous system is a network of chemical wires and a special center that controls the entire body. It is a complex group of specialized nerves known as neurons that work to transmit signals between parts of the body. The nervous system works to integrate a very large number of information and then issues appropriate reactions and this is done by sending electrical impulses to the responding organs of the body.
Technologies that generate electricity from the human body .
human blood flow
A team at Fudan University, which was founded in 1905, worked on converting blood flow in blood vessels into electrical energy, and the team succeeded in this by using carbon nanofibers. This idea was inspired by the idea of hydroelectric energy, just as electricity is generated by the flow of water, so electricity is also generated by the flow of blood inside the arteries to form a source of energy that does not depend on the weather or even the climatic atmosphere..
By applying this technology, we can generate energy in medical devices in a much easier way "such as the pacemaker." It has not yet been determined how much energy we can extract from this process; Therefore, we need to conduct more tests so that it can be applied periodically and directly to humans.
tears and saliva
According to a new study conducted at the University of Limerick, founded in 1972, we can generate electricity from the enzyme "lysozyme", which is found in both egg whites and is also found in human tears and saliva. This enzyme has a piezoelectric property, as it can convert mechanical energy into electrical energy.
The researchers also confirmed that such a discovery can be used to activate the drug in the body and work to control it, and it can also act as biomedical machines..
walking steps
The British company Pavegrn, which specialized in the field of clean energies, began working on converting the kinetic energy that results from walking steps into electrical energy, through the use of an adjustable floor system with multiple tasks, and equipped with a wireless transmitter that allows data capture, in addition to turbines It extracts electrical energy from the movement of walking.
The flooring system that we talked about is an idea inspired by the sport of walking, when a person walks, a process of friction occurs between him and the ground, and then the generators that are located in the floors move recursively from their primary place, and then kinetic energy is generated through electromagnetic induction.
This idea is applied in the streets where the energy of one step can light a street lamp only 30 seconds, but with the large number of pedestrians we may be able to generate more and more electrical energy.
Add to your information: In one step a person generates approximately 5 watts of energy
bioenergy cell technology
Researchers have recently worked on developing new technologies that generate energy in a simple form from the human body, and use it to operate electronic devices that are used permanently..
At the University of California, San Diego, USA, a team of researchers revealed that this technology simply relies on a small network worn by humans, and that network contains bio-energy cells and also contains electricity generation units that depend on movement, in addition to electric capacitors.
Looking at that study that was published for the first time in the scientific journal "Nature Communications", we find that all the components of that small network that the human wears are flexible and washable and can also be easily installed on the human body, i.e. on clothes.
One of the most important researchers in this technology is researcher le yen at the University of San Diego. He said that the idea of this technology was inspired by sustainable energy networks that work permanently to exploit wind energy, solar energy, electromagnetism and other clean renewable energy sources to try to meet the needs of cities for electricity.
" website " Tech explore
On the “Tech explore” website, which specializes in technology, le yen added important statements, stating that this new technology works to generate energy from all the different parts of the body and then works to store it in order to meet human needs in operating electronic devices, as the team The researcher explained that this system is generally made up of vital cells that generate energy from sweat! Yes, from sweat, as it is tightly installed inside the shirt that the person wears near the chest, and he has also worked on other units that work to generate energy from movement and are installed on the outer parts of the shirt, specifically on the arms and sides of the chest in order to generate energy from the movement of the arms during Walk or run.
Researchers have confirmed that generating that energy from movement or sweat allows us to operate electronic devices continuously and quickly. Until the body used to stop moving .
This technology is equipped with super capacitors that store the energy that is generated in order to be used when it is needed
This technique was practically tested through working sessions that lasted for thirty minutes, where the volunteer wears the small net and then does some sports exercises over a period of time "ten minutes". And that system succeeded in this way by generating a battery of energy sufficient to operate a wristwatch “equipped with an LCD screen” for half an hour..
