As electronic chips get smaller and more powerful, they can overheat, reducing their reliability and lifespan. Overheating arises when phonons — quasiparticles that carry heat — become blocked at ...

Scientists in Japan have developed a new organic device that can harvest energy from heat. Unlike other thermoelectric generators, this one works at room temperature without a heat gradient. Usually, ...

Thermoelectric generators built entirely from food-grade hydrogels and vanillin harvest heat from hot meals to power edible displays that change color when food reaches safe eating temperature.
