Piezoelectric effect is when certain solid material is compressed under mechanical stress, and it develops a voltage potential by accumulating electrical charges. French physicists Jacques and Pierre ...

One of the reasons gold is so valuable is because it is highly unreactive—if you make something out of gold, it keeps its lustrous radiance. Even when you can react it with another material, it’s also ...

Low-dimensional piezoelectric semiconductor nanomaterials, such as ZnO and GaN, have superior mechanical properties and can be integrated into flexible devices that can be subjected to large strain.

UD engineers are the lead inventors on a new patent for making piezoelectric devices, such as sensors and actuators, using Nodax®, a biodegradable, bio-based polymer. Every year, more than 400 million ...

Piezoelectric materials hold great promise as sensors and as energy harvesters but are normally much less effective at high temperatures, limiting their use in environments such as engines or space ...

Piezoelectric motors are increasingly popular for linear motion, but the design of the accompanying drivers is very different from those used by traditional electromagnetic motors. Employing the ...

Drums! You hit them, and they vibrate. It’s kind of fun. Piezoelectric elements can create electric current when they vibrate. [Will Dana] put two and two together to try and charge his phone on his ...
