Note on a piezo-electric generator for audio-frequencies

Piezo-electric Thick Films for Sensing

Monolithic piezoelectric sensors commonly used for acoustic emission and ultrasonic inspection are non-conforming, bulky, costly and heavy. This means they do not fit well to complex geometries, they can be susceptible to damage, and on larger structures their cost and weight can be prohibitive. An alternative to this is the use of piezo-electric thick films, which comprise of piezo-electric pa...

A Three - Channel Piezo - Electric Pressure Recorder

High Output Piezo/Triboelectric Hybrid Generator

Recently, piezoelectric and triboelectric energy harvesting devices have been developed to convert mechanical energy into electrical energy. Especially, it is well known that triboelectric nanogenerators have a simple structure and a high output voltage. However, whereas nanostructures improve the output of triboelectric generators, its fabrication process is still complicated and unfavorable i...

Eco-Friendly Electricity Generator Using Scintillating Piezo

The concept is to capture the normally lost energy surrounding a system and converting it into electrical energy that can be used to extend the lifetime of that system’s power supply or possibly provide an endless supply of energy to an electronic device which has led to power harvesting. One of the most interesting methods of obtaining the energy surrounding a system is to use piezoelectric ma...

Control Design for a Piezo-Electric Dual-Stage Instrumented Suspension

The servo control design for a piezo-electric dual-stage instrumented suspension to achieve windage vibration reduction for high track density recording is presented in this paper. The servo design exploits the information available from both the sampled position error signal (PES) and a continuous time instrumented suspension signal (ISS) available from an instrumented suspension. The ISS from...
