- Victor, NY - New Scale Technologies, Inc. announces successful
operation of its SQ-115C piezoelectric SQUIGGLE® motor
from room temperature to a new low temperature of less than 4
Kelvins. The cryogenic motor had previously been proven for
operation down to 100 Kelvins.
In addition to the lower operating temperature, the cryogenic motor
is now available with a metal housing for faster integration into
systems. New Scale continues to offer the motor without housing for
more space-sensitive applications.
"The cryogenic SQUIGGLE motor is easy to control and performs well
inside our cryostat at 0.03 Kelvins," said Dr. Ben Varcoe of the
physics department at the University of Sussex, UK. "We use it to
tune a superconducting microwave cavity into resonance with an
atomic transition."
Other applications include basic materials research at cryogenic
temperatures, cooled optical alignment, and research sample
manipulation and positioning.
Because the SQUIGGLE motor can operate continuously from room
temperature to 4 Kelvins, it is also ideal for infrared imaging,
where the optics move out of alignment as the camera temperature
changes. The SQUIGGLE motor can adjust optical alignment
continuously, allowing the camera to be focused at room temperature
and maintain focus as it is cooled. Current techniques require the
user to manually adjust the optics to be out of focus at room
temperature, calculating the expected change in position with
temperature so that the optics move into a final focused position as
the camera reaches its operating temperature. SQUIGGLE motors
eliminate this exacting and time-consuming task.
"Through aggressive R&D and our partnerships with SQUIGGLE motor
users in industry and research, New Scale continues to expand the
number of applications for this innovative motor technology," said
New Scale President David Henderson. "Precise, high-efficiency
positioning at liquid helium temperatures has been on the wish list
of space and cryogenic researchers for years and these motors
deliver it."

About New Scale Technologies
New Scale Technologies, Inc. (www.newscaletech.com)
makes miniature ceramic motors that enable our customers to create smaller products.
Our patented SQUIGGLE motors are bigger than MEMS devices but
smaller than conventional motors. We generate precise movement using
ultrasonic vibrations, which makes our piezoelectric motors
powerful, precise, simple, and compatible with extreme environments.
