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 ...

Piezo Trigger Switch circuit described here is a microcontroller-compatible shock/impact sensor switch module works on 5VDC supply. The whole circuit can be assembled on a 5×7 cm common circuit board.

Flexible piezoelectric sensors are essential to monitor the motions of both humans and humanoid robots. However, existing designs are either are costly or have limited sensitivity. In a recent study, ...

Advances in materials science stemming from research in South Korea are leading to higher-performance piezoelectric and triboelectric, and self-powering, sensors. How researchers are modifying basic ...

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 ...

Scientists have developed a new algorithm and circuit technology allowing high-frequency piezoelectric resonators to be used for phase locked loops (PLL). It was confirmed that these operate with low ...

Piezoelectric power, or electricity produced in response to applied mechanical stress, keeps popping up on our radar. Recently, we looked at a French city’s plan to implant piezoelectric microsensors ...
