Hydrogen Detection Using Sensor

Abstract

To satisfy the needs of future hydrogen economy, there are different kinds of hydrogen (H2) sensors, which utilize various systems (e.g., opposition based, optical based, impetus based, electrochemical based, flimsy and thick film based, chemo chromic based, Schottky based, MEMS-based, and surface acoustic wave (SAW) based) to distinguish H2 gas. Among these sensors, the SAW sensor has benefits that take into consideration distant remote activity and a high potential in aloof sensors.
