This engineering study examined how a DC bias electric field affects the resonance frequency shift of a PMN-PT/tin piezoelectric microcantilever sensor during humidity detection. The authors report that applying a bias field enhanced the relative resonance frequency shift, with a maximum enhancement of more than…
