Latest Research Proves Wearable T-Shirts and Hand Bands Can Convert Body Heat into Electricity

North Carolina (NC) State University in the US, is conducting research to convert body heat into electricity through T-shirts and ArmBands. Associate Professor Mr. Daryoosh Vashaee is a member of the development team.

He stated that a team of scientists are developing Armbands and T-shirts that convert body heat into electricity. With the help of Thermo-Electric Generators (TEGs), the unused heat will disappear. Thermally conductive material is used in making of the T-shirts and armbands.

The latest research suggests that daily wearable T-shirts can supply up to 20 microwatts per square centimeter. Wearable’s will generate electricity by using the variations of outside temperature and body temperature.

The entire system set up is just 2 millimeters thin and flexible. Generally, Upper arm considered as the heat harvesting area in the human body. Also, temperatures are high around the upper arm areas.  Basing on the body areas and the heat generating capacities, wearable’s are designed.

Armbands and T-Shirts can make the exact contact with the skin. TEG’s in T-shirts are generating 6 microwatts per square centimeter in normal conditions and can generate 16 microwatts per square centimeter when running.

The research will be helpful in the field of medical science for a long term.  Health monitoring devices can be developed that can monitor heartbeat, physical and environmental variations which might prevent Asthma-like diseases.

The heat converted electricity can be used to charge some of the devices like Mobiles, iPods. In the past, the same group has tried to do the same research and development but failed to achieve the success.
