A New Study Developed a Fabric to Powering Wearable with Body Heat

Wearable biosensors and transmitters have features of the health monitoring. These devices are now ‘creatively miniaturized’, said Trisha Andrew from the University of Massachusetts Amherst. Trish Andrew and one of her fellow Linden Allison reported that they have developed a fabric. This fabric can power these wearables such as activity tracker.

Earlier, in an online version of the Advanced Materials Technologies, the Allison and Andrew explained the theory. They said body heat is able to produce power due to the difference between body temperature and atmospheric cooler air. Material that has high electrical conductivity coupled with low thermal conductivity was the key material for conduction of electrical charge. She summarized that they capitalized insulating properties of fabrics for finding solution on the problems faces by the electronics community.

Researches showed that fabric could collect a small amount of electricity from the human body over the duration of 8-hours. However, the material is very expensive, inefficient, and toxic; thus, development of this can be hampered.

Andrew said, their study can develop the fabric in an inexpensive way and the material is biocompatible and flexible. This material is lightweight and can be used cotton as it has the thermoelectric properties.

The researchers are taking benefit from the properties of fabric such as thermoelectric nature and maintaining the temperature gradient. This can develop electrical energy from heat from longer periods and continuous wear. This can ensure conductive material from mechanically, electrically, and thermally stable. The researchers measured surface electrical conductivity and coating with a custom-built probe, which conducts the weaves than tighter material.
