Cryogenic SQUIGGLE™ Motor Operates at 100 Kelvins
Linear Actuator Enables New Imaging Systems and Scientific Instruments

September 14, 2004 - Victor, NY -
New Scale Technologies, Inc. has demonstrated a cryogenic version of
their patent-pending SQUIGGLE motor that operates from room
temperature to 100 kelvins. The tiny SQUIGGLE motor is an ultrasonic
piezoelectric actuator that uses vibrations in a threaded bushing to
directly rotate a mating screw. Resolution better than 50 nm is
achieved over several millimeters of travel. See
How They Work
for more information on the SQUIGGLE motor operating principle.
“This is a truly unique positioning technology,” stated David Henderson, President of New Scale. “No
other actuator has such a small size and wide operating temperature
range combined with outstanding stroke and resolution.”
A special version of the SQUIGGLE motor was constructed with cryogenically compatible materials and higher
voltage drive electronics. These changes compensate for the effects of cold temperatures and allow the motor
to continuously operate from room temperature to the temperature of liquid nitrogen. The company is planning
future research to develop motors for temperatures as low as 4 kelvins.

Targeted Applications for Cryogenic SQUIGGLE motors include:
- Cryogenic imaging systems for remote sensing and security surveillance.
- Basic materials research in cryostats.
- Microelectronic inspection and testing using cooled ultra-sensitive photon detectors.
- Nanometer optical alignment in NASA’s new cryogenic space telescopes.
- Opening and closing heat switches in NASA’s cryogenic cooling systems.
