Like all ceramics, piezo ceramics are brittle materials that are well suited to handling compressive loads but are highly sensitive to bending, shear and tensile loads. A number of mechanical ...

The P-878 DuraAct Power piezo patch transducer from PI Ceramic uses an operating voltage of only -20 to 120V compared to the high driving voltages of 250 to 1000V typically used with alternative ...

New perovskite-related material could find applications in sensors, wearables, and printed electronics ...

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 ...

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 ...

A research team led by Dr. Lim Sang-kyu in DGIST's Department of Energy and Environmental Technology has developed a smart fiber sensor that can detect natural disasters such as landslides in real ...

A research team has developed a machine learning-based acoustic sensor for speaker recognition. The team fabricated a flexible piezoelectric membrane by mimicking the basilar membrane in the human ...

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 ...

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 ...

Sensors used to monitor extreme environments need to provide reliable measurements despite high temperatures and harsh conditions. Now, researchers have developed a piezoelectric sensor that works at ...
