This paper presents a new boost converter for thermoelectric energy harvesting. The output voltage is regulated at 3.6 V for use with embedded systems. The booster reaches high efficiency at low input voltages of few 10 mV. A first prototype operates at about 15 mV input voltage with an efficiency of 45%. At 120 mV input voltage the efficiency increases to 74%. Using a 30x30mm sized low cost thermoelectric generator (TEG) in combination with the new developed booster, enough energy can be harvested to power an embedded wireless sensor.
