Engineers Create Hydrogel Patch Capable of Converting Overheating Phone Batteries to Electricity

Thin hydrogel film straps to phone batteries to convert waste heat to electricity. The new polymer-based film transfers electrons when heated to generate power. The water inside the hydrogel then evaporates to cool the patch has a cooling effect.
