Softening of thermoelectric generators (TEGs) allows conformal contact with arbitrary-shaped heat sources, which offers an opportunity to realize self-powered flexible applications. However, existing flexible thermoelectric devices inevitably exhibit reduced thermoelectric conversion efficiency due to the parasitic heat loss in high-thermal-impedance polymer substrates and poor thermal contact arising from rigid interconnects. In this talk, I would like to introduce various state of the art flexible thermoelectrics for self-powered applications. In particular, our recent efforts to improve the thermoelectric performance of compliant organic/inorganic TEGs will be highlighted which facilitate to achieve high energy conversion efficiency in TEGs capable of conforming to 3D surfaces of heat sources simultaneously. |
