Heat-to-Power technology or thermoelectrics (TEs), pyroelectrics (PEs) to power future wearables, homes, vehicles, consumer and Military equipment

Many electrical and mechanical devices, such as car engines, produce heat as a byproduct of their normal operation. It’s called “waste heat,” and its existence is required by the fundamental laws of thermodynamics. Heat-to-power technology is also other major opportunity to make use of any waste heat exiting through engine …
