Scientists Introduced Wearable Devices That Charges By Human Temperature

According to the media SciTechDaily, researchers from the University of California and many universities in China have developed a low-cost wearable device that uses the human body as a biological battery.

This concept sounds like the plot in the "The Matrix". AI controls the world and turns humans into biological batteries to support the entire AI system’s operation.

Of course, this newly developed wearable self-generating device is not so magical. Research papers published in "Science Advances" discussed this technology. It has a certain degree of flexibility. Users can wear it like a ring, bracelet, or any other accessory that touches their skin. It also uses thermoelectric generators to convert the temperature inside the human body into electrical energy.

"In the future, we hope that (your body) can provide electricity for your wearable electronic devices without the need of batteries," said Xiao, an associate professor in the Department of Mechanical Engineering at the University of California. "The advantage of the thermoelectric device is that you can wear it, and it can provide constant electricity."

With this device about the size of a sports wristband, a person can generate about 5 volts of electricity while walking, which is more than the power that many smartwatch batteries can provide. Although there are still some problems in the design, Professor Xiao believes that his team's equipment will be available in the market within 5 to 10 years.
