New Scale Technologies (NST)

Embedded Motion Modules Make Great Products Smaller

Founded in 2002, NST develops, licenses and manufactures standard and customized embedded motion modules that fit on your fingertips. These include rotary and linear smart stages that incorporate our patented and proprietary technologies: SQUIGGLE® and UTAF piezoelectric ultrasonic motors, position sensors, precision bearings, drive and control circuits, and microprocessors with closed-loop firmware that connect to New Scale Pathway® PC software. 

Our M3 micro mechatronic modules require only battery power and high-level digital commands to produce sub-micrometer precision movements. M3 smart stages are easy for customers to integrate into wearable, handheld, portable and battery-powered products to move very small optics, produce haptic feedback, and miniaturize complex instruments. For example, we use our M3 stages to create our multi-probe manipulator (MPM) system for electrophysiology. 

New Scale Technologies uses ISO 9001:2015 and ISO 13485:2016 certified quality management systems.
