Flexible Thermoelectric Thin Film Devices

Flexible thermoelectric devices (F-TEDs) thin film has been converted heat from chest skin energy to electrical energy. We proposed the novel uni-leg TEDs thin film using a polyimide (PIM) flexible substrate as low thermal conductivity and minimize heat losses, n-Bi2Te3 thermoelement very good properties at low temperature and Ag electrode thin films as non-oxidization fabricated by DC magnetron sputtering method and annealed this film at 473 K for 8 min. The F-TEG thin film placed on chest skin has been generated maximum output electrical voltage 8.90 mV and electrical power 1.20 μW cm−2 at different temperature between the chest skin and ambient air about 5 − 7 K.
