New Scale Awarded Fundamental US Patent for Piezo SQUIGGLE Motor Technology
17 September 2005
The U.S. Patent and Trademark Office has granted New Scale Technologies, Inc. a fundamental patent for its revolutionary SQUIGGLE motor design. Made of piezoelectric ceramics and other non-magnetic materials, the tiny SQUIGGLE motor has applications in nanotechnology research, microelectronics, optics, lasers, biotechnology, medical devices, aerospace and defense, fluid control, and office/consumer products including mobile phone cameras.
Patent Number 6,940,209 issued on September 6, 2005.
"This fundamental patent on our SQUIGGLE motor technology validates its unique design," said New Scale president David Henderson. "It gives us key intellectual property protection as we continue to develop new, smaller SQUIGGLE motors and pursue additional commercial applications."
The SQUIGGLE motor design uses a threaded nut and screw to create precise linear movement in a very small space. Piezoelectric ceramics create ultrasonic vibrations in the nut, causing the screw to rotate and translate with high precision. Since introducing the first SQUIGGLE motor in 2004, New Scale has continuously improved the performance and reduced the size of its miniature motors. The latest models are less than 3 mm in diameter.
SQUIGGLE motors are smaller, more precise, less expensive and more efficient than conventional electromagnetic motors. With its unique materials and construction, the SQUIGGLE motor operates reliably in extreme environments such as vacuum, very cold (sub-kelvin) temperatures, and very high magnetic fields.
A key application is control of auto focus and optical zoom lenses in mobile phone cameras, where the motor’s compact size and low power consumption offer advantages over current technology. Because it is non-magnetic, it also offers unique benefits in medical device development; for example, creation of tiny drug delivery pumps that are MRI-safe and image compatible.
