Piezoelectric motors move miniaturization forward
Article in Electronic Products magazine – This article compares piezo motors to other motor technologies for micro cameras, including miniature electromagnetic motors, voice coil actuators, liquid lenses, and piezo bimorph actuators. It then compares two types of piezo motors that have been commercialized for micro camera applications.
Simple ceramic motors … inspiring smaller products
Technical paper presented at Actuator 2006 By David Henderson – introducing the SQUIGGLE motor.
Micro moves
Article from Machine Design Magazine – by David Henderson. Motors that can precisely position loads with micrometer-scale accuracy are now inexpensive enough for consumer electronics.
