Abstract:The relationship between the output voltage from a poly-lactic acid piezoelectric film sensor and the bending angle of it can be derived by analyzing the resonance frequency of the sensor changes with the bending angle using the finite element method. The proposed sensor was excited and its oscillation was observed using the piezoelectricity of poly-lactic acid. The output voltage was amplified by resonating a brass plate with a slit. The frequency changes significantly with bending because the change in frequ… Show more
