The adsorption mechanism of formaldehyde molecules on ZnO-SAW sensor at a different relative humidity

In this paper, the ZnO-SAW sensor is exposed to different concentrations of HCHO/H2O mixed gas, and the sensing performance of formaldehyde moisture is evaluated by testing the resonance frequency shift. The experimental results show that the sensitivity of the ZnO-SAW sensor to detect formaldehyde...
