Power Generator Harnesses Body Heat to Energize Medical Devices
As body-worn and implanted medical devices are continuing to proliferate, the need to utilize power from something other than batteries increases. Researchers from Huazhong University of Science and Technology developed a wearable flexible device that can produce electricity from body heat. The device relies on two gel electrolytes, allowing the final device to be flexible and produce as much as 0.7 volts and 0.3 µW. Since the system works using the thermogalvanic effect, the higher the difference between the body temperature and the environment, the greater the voltage. While…
