The Thermobility WPG-1 from Nextreme Thermal Solutions Inc., Durham, NC, uses heat as a source of electricity for low-power wireless applications. The solid-state, thin-film device converts heat into electricity for a variety of self-contained autonomous systems, providing a constant 3.3 VDC, 4.1 VDC, or 5.0 VDC output to electrical loads of 15 kilohm or higher. The WPG-1 consists of a pin-fin heat sink, a custom circuit board, the eTEG HV56 thermoelectric power generator module, and a metal attachment plate that is applied to the desired heat source. It incorporates a Linear Technologies LTC3108 ultra-low-voltage step-up converter and power manager chip to provide up to 1 mW at temperature differentials as low as 15–20 K relative to ambient.
