Piezomotors “Ultrasonic Motors”
Piezoelectric Notions
“Piezoelectricity is the ability of certain crystals to generate a voltage in response to applied mechanical stress. The word is derived from the Greek piezein, which means to squeeze or press. The piezoelectric effect is reversible in that piezoelectric crystals, when subjected to an externally applied voltage, can change shape by a small amount. The deformation, about 0.1% of the original dimension in PZT, is ....etc

Nonintrusive manipulation by standing-wave acoustics has been widely used for levitation and trapping of macroscopic objects.1 The standing-wave field creates an acoustic radiation force on the object that depends on its size and acoustic parameters.2 In the present article we demonstrate size-selective separation and retention of latex spheres inside a small-diameter flow-through capillary by use of an ultrasonic radiation trap. The work aims at rapid in-flow detection and separation of specific molecules via antibody-coated latex spheres. Ac ....etc
