A self-powered device without electricity generation from body temperature and battery is under development

Small devices such as smartphones are progressing year by year, but as a result of seeking high-speed computing that requires more power with limited batteries,Smartphone battery flamesIt is causing a dangerous situation to do. One of the solutions to such a problem with the battery is the development of a self-powered device that does not require a battery, and the University of Southern California says "Body temperature generator"We are developing.

University of Southern California is a research consortium devoted to developing low-power, battery-free healthcare productsAdvanced Self-Powered Systems of Integrated Sensors and Technologies(ASSIST) "is held. As part of ASSIST's research, the development of a compact thermoelectric generator (TEG) capable of driving a wearable device is under way, and patch type and T-shirt type thermoelectric generators attached to upper arm, wrist and chest are completed It is.


A patch type thermoelectric generator attached to the chest is a wearable device that measures heart rate, movement, and breathing as it is, and the wristwatch type thermoelectric generator can measure organic compounds in air temperature, humidity and air It can be used as a wearable device.


Developing battery-less devices will benefit many devices as the battery becomes a bottleneck for all devices. However, at home power generation such as thermoelectric power generation due to human body temperature, it is difficult to generate sufficient electric power for smartphones and activity meter and other devices at present.

Meanwhile, self-generated power technology attracts attention in healthcare devices that do not require much electric power, and if batteries can be eliminated from implantable medical devices such as pacemakers, there is no need for surgery to replace batteries I will. New startup aiming to connect AI to Mr. Eulon Mask's human brain "NeuralinkIt is thought that the possibility of brain implants such as "can be expanded."

ASSIST expects that it will take three years for thermoelectric power generation technology to be fully introduced to the market, and it will take some time before "battery-free device" appears. In addition to the University of Southern California, the development of devices that do not require batteries is being done, and in September 2017, a battery-free smart watch from Indiegogo of Cloud Funding "MATRIX PowerWatchIt is scheduled to be shipped.
