This paper presents, for the first time, a coupled piezoelectric-circuit finite element model (CPC-FEM) to analyze the power output of a vibration-based piezoelectric energy-harvesting device (EHD) ...

Piezoelectric shunt damping is a well known structural vibration control technique that consists in connecting an electrical circuit to a piezoelectric transducer attached to the structure. In the ...

Piezoelectric sensing is a popular sensing method that utilizes the piezoelectric effect to efficiently measure changes in dynamic forces like force, acceleration, or pressure by converting them to an ...

At the time of acquisition, Fairchild was highly active in the field of piezoelectric power converters. For instance, its FAN8831 single-chip piezoelectric actuator was a product that consisted of a ...

The piezoelectric sensor (piezo disc) drives a load resistor of 1MΩ in parallel with a 5.1v zener diode (there is a 10KΩ resistor in between) just to protect the LM393 comparator against any large ...

Keep the side length of the piezoelectric material as d 1 = 400, the thickness of the piezoelectric material h 1 = 350μm, change the thickness h 2 of the semiconductor membrane, start from h 2 = 5μm, ...

This article presents a Class-D audio amplifier for capacitive piezoelectric speaker loads. Employing a dual voltage feedback (VFB)/current feedback (CFB) topology, the amplifier is capable of damping ...
