| Summary: | This paper presents finiteelement method (FEM) simulation using P(VDF-TrFE) as piezoelectric material for Internet of things application. The simulation was conducted using COMSOL Multiphyisc 5.1 to study the resonance frequency, stress, displacement and load dependence for the P(VDF-TrFE) piezoelectric as a batteryless sensor whenever there is mechanical vibration present on the piezoelectric material. The simulation results obtained with maximum displacement and stress are 0.3 mm and 1.01×107 N/m2 at resonant frequency of 131 Hz.Electrical properties with maximum voltage of 24.2 mV power output of 3.2 nW was obtained at 18 6 kΩ under the acceleration of 1 g at resonant frequency. The optimized design of P(VDF-TrFE) piezoelectric sensor was applied in the step monitoring application via internet of things (IoT)system. |
