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, ...
New work could help design electronic devices in which heat can be guided in certain directions, minimizing heat loss ...
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.
