The scientists They found a way to turn the human body into a "biological battery" through a low-cost, wearable device. Using a small thermoelectric generator that can be worn as a ring or bracelet, the researchers at University of Colorado Boulder were able to convert body heat into enough electricity to power an electronic device. The scientists' findings were published in the journal Science Advances, which is run by the American Association for the Advancement of Science (AAAS).
This invention is somewhat reminiscent of the "Matrix", where robots have enslaved humanity, using human bodies as batteries, drawing their energy.
This device can produce about 1 volt of energy per square centimeter of skin - less energy per area than most existing ones. batteries. However, it is still enough to power electronic devices such as watches or fitness trackers. This wearable device could be adapted to provide power and eliminate the need for batteries in pacemakers, drug delivery pumps and other medical devices, according to the researchers.
Jianliang Xiao, senior author of the scientific article and associate professor at the Paul M. Rady Department of Mechanical Engineering at UC Boulder, stated the following: "In the future we will want to be able to supply wearable electronics Appliances, without the need for a battery. Whenever you use a battery, you run out of it and eventually have to replace it. The nice thing about our thermoelectric device is that you can wear it and it provides you with stable energy. "
Its flexibility and durability means that all it needs is close contact with it skin to convert a person's body heat into electricity.
"Our design makes the whole system stretchable without putting too much pressure on the thermoelectric material, which can be really fragile.", Xiao said, adding that any extra heat generated through exercise could also be captured and converted into electricity. energy.
Also, the material from which the wearable device is made makes it recyclable, while giving it the ability to self-medicate, which means that if torn, it can stick on its own within minutes.
The researchers predict that the device that turns the body into a "biological battery" could be on the market in 5-10 years.
