Integrating a complex, single-crystal material with "giant" piezoelectric properties onto silicon, engineers and physicists can fabricate low-voltage, near-nanoscale electromechanical devices that ...

Piezoelectric crystals are a class of materials that exhibit a unique property called piezoelectricity. These crystals generate an electrical charge when subjected to mechanical stress or strain, and ...

Use of an AC rather than a DC electric field can improve the piezoelectric response of a crystal. Now, an international team of researchers say that cycles of AC fields also make the internal crystal ...

High-temperature piezoelectric materials enable direct electromechanical transduction under extreme thermal conditions, extending the reach of precision sensing into aerospace engines, automotive ...

“Hey, Cortana.” “Hey, Alexa.” “Hey, Lyra.” “Hey, Robin.” “Hey, Siri.” If you’ve ever owned a quartz watch, received an ultrasound exam in a doctor’s office, or enjoyed a voice-controlled personal ...

Piezoelectricity is the ability of some materials such as crystals and certain ceramics, to generate an electric potential in response to applied mechanical stress or heat. If the piezo crystals are ...

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 ...

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 ...
