The PiezoWave™ was originally developed for applications within handheld consumer electronic devices such as mobile phones, but the product is now being integrated into many other applications, including other handheld devices, consumer electronics, medical technology applications, electromechanical door locks, advanced toys, cameras etc.
The PiezoWave™ motor consists just a few parts. Very small piezo ceramic elements surface mounted to a flexible printed circuit board connect to the drive rod through two drive pads. The design enables large-volume manufacturing to produce units at a very low cost.
When activated electrically, the piezo ceramic elements will vibrate at an ultrasonic frequency. The drive pads, which are used for transferring the movement from the elements to the drive rail, will move in an elliptical fashion due to flexural (bending) waves in the piezo element.
