A novel microscale multilayer PZT MEMS cantilever for resonant photoacoustic gas sensing
This paper reports a novel photoacoustic spectroscopy (PAS) gas sensor based on micro-electro-mechanical systems (MEMS) that achieves resonance matching between a multilayer PZT piezoelectric microcantilever and an H-type acoustic resonator. The device integrates the PZT thin film and exhibits a measured mechanical res...
