In this proposal we aim to contribute to the development of novel biological and chemical cantilever sensors, using a nonpiezoelectric layer made of a stiff and very light material such as non-oxide engineering ceramics, and a piezoelectric layer constructed of lead zirconate titanate. The effect of layer thickness and sample size on the sensitivity of the sensors will be characterized both theoretically and experimentally. A general understanding of the sensing capabilities of these ceramic sensors is not currently available, research is essential to gain an understanding of the enhancement of the resonance frequency shift per molecule mass change.
