FREIBURG, Germany--(BUSINESS WIRE)--Micropelt GmbH, manufacturer of thin-film thermoelectric chip-like devices, announces the TE-Power-Bolt, a voltage adjustable thermal battery that uses excess heat to generate electrical energy for devices that consume only a few milliwatts (mW) of power, such as wireless sensor nodes. With its micro-thermogenerator that is built into an M24 steel screw, the Power-Bolt can harvest energy from surfaces and structures from 10-20 degrees Celsius over ambient temperature or directly from hot liquids. Output power can range from 0.2 to over 15mW and is voltage-stabilized by an integrated DC-DC converter which can be set to fixed voltages between 1.2 and 5 Volts.
