The fabric can harvest body heat to power small wearable electronic devices
Many wearable biosensors, data transmitters and similar tech advances for personalised health monitoring have been "creatively miniaturised," said Trisha Andrew from the University of Massachusetts Amherst in the US.
However, they require a lot of energy, and power sources can be bulky and heavy, said Andrew.
The research, published in the journal Advanced Materials Technologies, describes that in theory, body heat can produce power by taking advantage of the difference between body temperature and ambient cooler air, a "thermoelectric" effect. Read More
