Tiny Piezo Motors for Mobile Phone Camera Auto Focus and Optical Zoom
The world market for mobile phones cameras is forecast to be nearly
one billion by 2009. Handset makers are moving to incorporate
high-end 3MP and 5MP image sensors in phone cameras, in order to
produce image quality that rivals stand-alone digital cameras.
However, achieving that image quality also requires high-end
precision optics and both auto focus and optical zoom capabilities,
to project a sharp and clear image onto the sensors.
SQUIGGLE motors meet this need by enabling auto focus and optical
zoom in smaller phone handsets, with little drain on the batteries.
The robust miniature motors combine the precision needed for auto
focus, with the long travel needed for zoom, so that both functions
can be performed by the same motor.
Ideal Motor for Mobile Phone Cameras
Conventional motors are too large and use too much power to be
practical for mobile phone cameras. SQUIGGLE motors, on the other
hand, are a simple device that is easily miniaturized to phone
camera dimensions. Compared to conventional electromagnetic motors,
SQUIGGLE motors:
- maintain position when the power is off
- use 90 percent fewer parts - no gears! - for high ruggedness
- are 5x times more efficient for low heating and long battery life
- are 10x more precise for great picture quality
- operate reliably over a wide temperature range - from the slopes, to a hot auto interior
- offer quiet, ultrasonic operation
SQUIGGLE motor evaluation kits are available for
purchase today. High-volume production can begin six months after
order placement.
