World's Smallest Linear Motor
Though tiny, the newest SQUIGGLE motor ups the ante on force and positioning

Measuring just 1.5 x 1.5 x 6 mm, this piezoelectric linear motor is in fact the smallest of its kind. "It's about two times smaller than the next smallest ultrasonic motor," says Dave Henderson, New Scale's president and chief engineer.
Though small, the motor doesn't skimp on capabilities. It has a push force of 20 gm, which Henderson claims is about 10 times better than previous ultrasonic motors. And this SQUIGGLE motor also ups the ante on accuracy and precision with a positioning resolution of 0.5 µm. "That's about 10 times better than other piezoelectric motors and 20 times better than small electromechanical motors," Henderson says.
