Piezoelectricity is a property of certain materials to become electrically polarized under strain and stress. This phenomenon has been studied extensively since it was first discovered in the mid-18 ...

Heat and pressure can deteriorate the properties of piezoelectric materials that make state-of-the-art ultrasound and sonar technologies possible -- and fixing that damage has historically required ...

Piezoelectricity is used everywhere: Watches, cars, alarms, headphones, pickups for instruments, electric lighters and gas burners. One of the most common examples is probably the quartz watch, where ...

A close-up image of a dark crystal held between two metal rods on a yellow background Researchers created a lead-free piezoelectric material (shown under a microscope), which could provide a ...

A pair of chemists at Michigan State University has observed the piezoelectric effect in liquids for the first time. In their paper published in The Journal of Physical Chemistry Letters, Md. Iqbal ...

A novel piezoelectric film made from polyethylene (PE) reportedly combines mechanical flexibility with a very high piezoelectric response. In fact, it reportedly doubles the properties of commercially ...

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 ...

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 ...

Researchers have found a new method to induce the piezoelectric effect in materials that are otherwise not piezoelectric. It can pave the way for new uses and more environmentally friendly materials.
