How do piezoelectric accelerometers — vibration sensors — work? The force caused by vibration or a change in motion (acceleration) causes the sensor's mass to “squeeze” contained piezoelectric ...

The ability to measure, monitor, and analyze vibration is essential to many industries and areas of research & development. Unfortunately, the proper methods for creating an accurate and repeatable ...

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 ...

Smart sensor nodes are the “canaries in a coal mine” for the industrial IoT, sensitively monitoring industrial equipment for vibrations, electrical current and voltage changes, temperature, sound, and ...

Part 1 of this series addressed the advantages and disadvantages of various vibration sensors; Part 2 examined signal conditioning and system hardware selection and configuration. I’ll wrap up by ...

Before humans discovered ultrasound for a variety of medical, technical and military applications, nature had perfected it over millions of years for navigation under and above water. Dolphins and ...
