Abstract

In this work, we present a compact self-powered wireless gas sensor node based on photovoltaic (PV) energy harvesting (EH). Instead of a bulky and power-hungry gas sensor with separate gas signal processing (GSP) circuits, a mm3-sized colorimetric sensor film is integrated with a PV cell, and the GSP function is seamlessly embedded within EH circuits. Also, a dual-input shared-inductor boost converter is used to improve the EH efficiency under gas exposure. Offset cancellation is performed in GSP circuits to provide accurate gas-sensing readout without any external trimming.
