One of the most eagerly anticipated elements of the upcoming BlackBerry Storm 2 is its new touchscreen, which is promised to address the disappointing display of its predecessor. Details of the new ...

Today’s step-down DC/DC converters – often converting 48 V down to single-digit voltages — are highly refined topologies, ...

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 ...

A new, inexpensive method to 'print' large-scale sheets of two dimensional (2D) piezoelectric material offers tremendous opportunity for new piezo-sensors and energy harvesting. Researchers have ...

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

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 ...

Ceramic speaker manufacturers specify a maximum voltage of 14 to 15 V p-p to produce the highest levels of sound pressure. The question quickly becomes how to generate these voltages from a single ...
