There have been many different ideas presented for increasing the acoustic output of a piezo buzzer or ultrasonic transducer. Most of them involve rather complicated circuitry that drives up the total ...

How does a piezoelectric transducer (actuator) work? Modern Piezo actuators are based on thin piezoceramic layers manufactured in a co-fired process to form a monolithic unit. They are also called ...

To increase the accessibility of piezoelectric transducers and actuators for OEM designers, manufacturers may package these devices inside a protective arrangement of flexures. This approach offers a ...

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 ...

Will piezoelectric-based speakers replace traditional speakers over the coming years in space-constrained devices? We have definitely seen the use of piezo transducers in e.g. high-end televisions ...

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 ...

Download this article in PDF format. Jacques and Pierre Curie, French physics, discovered the piezoelectric effect in 1880. When some solid material is mechanically compressed or stressed, the ...

Piezo elements are electromechanical transducers that convert mechanical forces (pressure, tensile stress or acceleration) into voltages. The inverse piezoelectric effect, precisely the opposite, ...
