Auto-focusing camera for phones

Atsana Semiconductor and the briefly-named 1 have formed a partnership to deliver auto-focus-capable cameras to mobile phone manufacturers.

The new camera technology, dubbed "Helimorph", is able to function within the confined space of a mobile phone because it differs from traditional focus technology. Most auto-focus cameras use electromagnetic transducers, which are bulky and power-hungry. The Helimorph, by contrast, is an actuator made out of a new piezoelectric ceramic material called PZT that changes shape when voltage is applied. That material is shaped into a helical structure, so that a small change in shape gets magnified into a large movement. That movement realigns the camera lens for optimal focus.
