Influence of Parasitic Capacitance on Output Voltage for Series-Connected Thin-Film Piezoelectric Devices

Abstract: Series-connected thin film piezoelectric elements can generate large output voltages. The output voltage ideally is proportional to the number of connections. However, parasitic capacitances formed by the insulation layers and derived from peripheral circuitry degrade the output voltage. Conventional circuit models are not suitable for predicting the influence of the parasitic capacitance. Therefore we proposed the simplest model of piezoelectric elements to perform simulation program with integrated circuit e… Show more

“…The range of voltage outputs is 1.8–3.1 V. The output voltages increased with increasing electrospun web thickness. Persano et al also have the same results for aligned arrays of nanofibers of poly (vinylidenefluoride-co-trifluoroethylene), but generating for a maximum voltage of 1.2 V for a thickness of 225 μm [ 46 ].…”

“…When the torque changed from 6.0 N·m to 10.0 N·m, the magnitude of the impedance at resonance reduced from 36 Ω to 18 Ω, while it increased from 19 kΩ to 40 kΩ at anti-resonance. Such distinct impedance characteristics can be explained by the presence of parasitic capacitances [24], which are considered to be connected to the piezoelement in parallel at resonance and in series at anti-resonance. These capacitive terms may have nonlinear dependence on the torque, as resulting from multiple capacitors formed by pairs of PZT-4 and electroplate.…”

“…As the Young's modulus decreases, the first five resonance frequencies also decrease. In addition to the Young's modulus, parasitic capacitance will also have an important impact on the output performance of the PEH [37,38]. The PEH can be regarded as an equivalent circuit network composed of infinite parallel branches composed of inductance, capacitance, resistance, ideal voltage source and ideal transformer, where each parallel branch represents a certain order of vibration mode.…”
