This flexible "glass fabric" armband converts body heat into ELECTRICITY
Byung Jin Cho, a professor of electrical engineering at KAIST is in charge of the team to develop the flexible, thermoelectric (TE) generator . The device is made by screen printing liquid-like pastes of n-type (Bi2Te3) and p-type (Sb2Te3) TE materials onto glass fabric. As a result, hundreds of TE dots are printed on the glass fabric with a thickness of hundreds of microns thick. When placed on the body, the band utilizes waste heat to generate power, similar in concept to how a photovoltaic panel takes the sun’s energy to make power.
