Abstract

In the field of autonomous sensors powered by energy harvesters, this work proposes and experimentally characterizes a power management circuit (PMC) for low-power thermoelectric generators (TEG). The proposed circuit combines and interconnects, in a multiplexed approach, two off-the-shelf PMCs so as to achieve the benefits of both. Thanks to this interconnection, the resulting circuit is able to start operating from a low input voltage (40 mV) with a satisfactory efficiency (up to 78 %), features that are difficult to achieve exclusively using one of these PMC alternatives.
