Harvesting Heat Differentials
PELTIER / SEEBECK effect
A thermoelectric device creates a voltage when there is a different temperature on 2 junctions of 2 metals, a property discovered by Seebeck in 1821. Conversely when a voltage is applied, it creates a
temperature difference (known as the Peltier effect).
There are a number of low cost Peltier elements available and these can be used ‘in reverse’ as generators
Heat
Cold ( heat sink)
N P- +
A heat source will drive electrons in the n-type element toward the cooler region, creating a current through the circuit. Holes in the p-type element will then flow in the direction of the current. The current can then be used to power a load.

Actuator Application
~100 μW energy available at 7 Kelvin temperature difference
Enough energy is available topower a TRV
