This technology uses the human body as a medium to power wearable devices. Researchers at the National University of Singapore (NUS) have invented a technique that allows a single device. Such as a mobile phone in a pocket, to wirelessly charge other wearable gadgets on a user’s body by utilizing the human body as a transmission medium.
The unique technology enables a single fully charged power source to run up to ten wearable gadgets on the body for more than ten hours. Additionally, it may capture unused energy from household or workplace gadgets to fuel the wearables.
Nature Electronics reported the results.
“Our unique technology has the potential to remove the need for batteries. Enabling device makers to significantly lower the size and cost of their products. “Jerald Yoo is an Associate Professor at the National University of Singapore’s Department of Electrical and Computer Engineering.
“Most excitingly, since our invention is battery-free. It enables next-generation wearable applications such as ECG patches, gaming accessories, and remote diagnostics,” Yoo noted.
The NUS team developed a receiver and transmitter device that exploits the human body. As a medium for power transmission and energy collection. Each receiver and transmitter is equipped with a chip that acts as a springboard for extending coverage over the whole body.
The transmitter is to attach to a single power source. Such as the user’s smartwatch, but many receivers may be put anywhere on the user’s body. The system then uses the energy harvested from the source to power several wearables on the user’s body through a mechanism called body-coupled power transfer.
Thus, the user will only need to charge one device. And the remainder of the devices worn may be charged concurrently from that one source.
