Most touchscreen panels have a limited type of haptic feedback or none at all. This is also true for many types of handheld or wearable devices like watches, touchpads, keyboards, a mouse, etc. The ...

The increasing miniaturization and sophistication of electronic products, ranging from consumer media devices to medical diagnostic tools to defense-related sonar applications, presents a bounty of ...

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 ...

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 ...

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 ...

Piezo sensors that can continuously monitor components as hot as 900°C have been realised by researchers at the Fraunhofer Institute for Silicate Research ISC. "We have already implemented our sensors ...

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, ...

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 ...

If you are engaged in an energy harvesting project that involves piezo sensors powered by vibrations, you might want to check out the most recent issue of Applied Physics Letters (Applied Physics ...
