Sheba Microsystems is a fab-less semiconductor company that develops high-end MEMS actuators for optical solutions including pixel-shift superresolution (SR), autofocus (AF) and Optical Image Stabilization (OIS) for miniature cameras. With their high speed and high repeatability, low power consumption, and small size, the Sheba MEMS actuators are ideal for such applications.
Such unique features are enabled by a novel electrode configuration in micro-electrostatic actuators invented by Sheba. This novel revolutionary actuator platform was enabled by the Sheba µPistons™ technology, where thousands of micro-size pistons and tubes are fabricated within a small footprint to interact with each other and generate forces able to manipulate large masses within a structure able to resist sudden drops.
