Designing with piezoelectric sensors might seem, at first glance, a bit trivial but make no mistake, there are certain pitfalls of which to be aware as well as diverse configurations and internal ...

National Cheng Kung University in Taiwan is experimenting with piezoelectric gated thin-film transistors. National Cheng Kung University in Taiwan is experimenting with piezoelectric gated thin-film ...

This circuit uses a thin piezoelectric sensor to sense the vibrations generated by knocking on a surface; eg, a door or table. Basically, it amplifies and processes the signal from the sensor and ...

New transistor technology boosts the body's electrochemical signals by 1,000 times, enabling diagnostic and disease-monitoring implants. The molecules in our bodies are in constant communication. Some ...

A designer and a senior engineer analyze a low-cost alternative for solid-state general-purpose impact sensing uses a standard piezoelectric device (PZT) an a 555 timer. When the piezoelectric device ...

For example, a 2-kN force properly applied to a cubic-centimetersized quartz crystal produces over 12.5 kV. Voltage created by an applied stress is called piezoelectricity. Unlike strain gages that ...

Piezo comes from the Greek word “piezein,” which means “squeeze” or “apply some pressure.” Whether they take form as a transducer or sensor, piezo components all operate as the result of some degree ...
