ADDITIVELY MANUFACTURABLE AND STRETCHABLE THERMOELECTRIC DEVICES

Abstract: a method of fabricating a wearable and elastically stretchable thermoelectric generator or other thermoelectric device can involve arranging thermoelectric pellets and printing a thermal insulation material alongside and/or around the thermoelectric pellets to form a core layer. the core layer can be cured, and a liquid metal can be selectively deposited on the thermoelectric pellets to form contact points. printing conductive ink can form stretchable electrical interconnects that define connections among the thermoelectric pellets via the contact points to form an initial middle layer that includes the stretchable electrical interconnects. printing a thermal interface material may form an initial outer layer positioned between the initial outer layer and an initial side of the core layer to form a layered assembly. the layered assembly may be inverted and receive additional printed layers building away from the core layer, such as an additional interconnect layer and an additional thermal interface layer.
