Energy Harvesting: Power generation with Peltier elements

Energy from waste heat

Peltier elements used as thermoelectric generators produce electrical current from waste heat. Essential is the temperature delta between the hot and cold side. The higher the delta the more energy is generated.

With Peltier technology the service intervals for battery replacement in small mobile instrumentation can be extended or even made unnecessary.
