If you do FDM 3D printing, you know one of the biggest problems is sensing the bed. Nearly all printers have some kind of bed probing now, and it makes printing much easier, but there are many ...

While learning about different types of vibration sensors for condition monitoring, I came across a cheap piezoelectric shock/tap/vibration sensor switch module hiding in a corner of my messy ...

A 1-op-amp circuit for processing the signal from a piezoelectric accelerometer. Accelerometers are used in instrumentation applications to measure a change in velocity with respect to time or an ...

Haptic technologies recreate touch sensations by applying a combination of force, vibration and motion to the user. Haptic technologies are also thought to be a $12.8 billion industry by 2022. In ...

When the piezoelectric device (PZT) detects a mechanical impact, it emits a signal that triggers the monostable (IC1), which in turn controls the output of the dual LED/phototransistor opto-coupler ...
