Newly-developed acoustic technologies used to move particles and create haptic feedback in mid-air have stirred the imagination of many researchers. Unfortunately, the complexity of the equipment ...

How piezoelectric materials are used to create a defined acoustic field. How this field, in turn, is used to develop modulate an electric field. How the combined acoustic and electric fields can ...

Researchers from Tokyo Metropolitan University have devised a new technology that allows the manipulation of small objects without having to touch them. The small objects are manipulated using sound ...

University Park, Pa. -- Manipulating tiny objects like single cells or nanosized beads often requires relatively large, unwieldy equipment, but now a system that uses sound as a tiny tweezers can be ...

Although their technique employs a method similar to laser trapping in biology, adaptable to a wider range of particle sizes and materials. The ability to move objects without touching them might ...

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 ...

Danisense's current transducers have been used by teams at CERN as part of a significant upgrade program. The Danisense zero-flux DC current transducers (DCCT) are used in the design of QTRIM power ...
