The clever folks over at [Novaetech SRL] have unveiled openQCM, their open-source quartz crystal microbalance. A QCM measures very minute amounts of mass or mass variation using the piezoelectric ...

The crystal in a crystal earpiece is a piezoelectric sound transducer. Back in the 1960s, these were fairly common in cheap transistor radios and hearing aids. Their sound fidelity isn’t very ...

The piezoelectric effect arises from the asymmetric arrangement of atoms in certain crystalline materials. When a piezoelectric crystal is subjected to mechanical stress, the deformation of the ...

High Curie temperature and high piezoelectric constant are challenges that most piezoelectric ceramics difficult to be ...
