The performance of new biosensor design -- Micro-ElectroMechanical Diaphragm (MEMD) -- made from PVDF piezoelectric polymer is reported. The resonant frequencies changing with featured size of MEMD are characterized. The resonant behavior in liquid media shows that the damping effect of MEMD is lower than that of MC. Yeast cell detection demonstrated the feasibility of using this platform as biosensor in real time detection. Finally, the preliminary study on microelectronic fabrication of MEMD is presented.
