Abstract

Semiconducting gas sensors that operated at room-temperature (around 25 °C) have been studied to monitor target gases. Furthermore, a self-powered gas sensor with no reliance on a battery or external power source was highly demanded to effectively reduce the power consumption and apply for practical environments. In this study, we designed the self-powered gas sensors by connecting ionic-activated semiconducting sensors, a promising candidate for room-temperature operation, with an oval-shaped piezoelectric generator, and light-emitting diode alarm. The effect of the divided voltage from the energy generator to the sensor on the sensing performance was analyzed. The self-powered sensor has an extremely low detection limit (4.32 ppb NO₂) with rapid and constant recovery (6 s) regardless of the NO₂ concentration. Additionally, the practical applicability was confirmed by the light-emitting diode alarms according to the NO₂ concentration in the atmosphere.
