Eamex Image Stabilizer Actuator

Tech-On: Eamex Corp. has developed an actuator for use in optical image stabilizers targeting phonecam modules. Compared to the previous electromagnetic actuators, it boasts a thinner profile as well as simpler structure, lower cost and reduced power consumption.
The prototype is as thin as 1.5 mm and measures 14 mm in diameter. The ion exchange resin that supports the lens holder expands and contracts to tilt the lens.
The maximum tilt angle and speed are ±2.9° and 14.13° per second, respectively. The power consumption is 15-35 mW. The drive voltage is ±4 V.
