According to reports, scientists have developed a non-invasive wearable device that can extract electricity from body heat. The base of the device is non-toxic and non-allergenic, made of ordinary old cotton fabric.


On this cotton fabric wristband, a special coating is applied to collect the body temperature "power generation". Theoretically, one end of the fabric contacts the human skin, and the other end is exposed to the air, and the temperature difference between the two ends is greater. The electric output is larger.


Researcher Trisha Andrew, associate professor of chemistry at the University of Massachusetts at Amherst, said: "Coating is an important part of the technology." The research team used to use other ingredients to make energy harvesting devices of the same principle, but unfortunately toxic.


At the same time, human sweat can improve conductivity. This technology is suitable as a stable trickle charger for batteries, which in turn powers a wearable device, such as fitness trackers and medical monitors, especially for the current popular sports. Exercise to create a wearable device, this technology may solve its charging problem.


The research was published in the journal Advanced Materials Technologies, and the research team said it has patented the technology and is currently considering using it for future charging of wearable products.
