1.AF and Zoom device for lens |
| We developed a microminiature AF camera module with an ion conduction actuator. | ||||||||||||||||||||||||
Good points
| * Low consumption electricity(0.03W)
| * Microminiature super light weight(0.015g)
| * Structure is simple, and with a few part marks, it is low cost
| * The low drive voltage(3 or 4V)
| * The positioning that is highly precise by a brief control circuit is possible
|
| The lens device of an existing cellular phone camera synchronizes a micro motor, a small cogwheel, and a small cam, etc. and moves the lens. It was necessary space that put the transportation parts, and had the limit in the miniaturization of the lens unit. |
| Our device need not use parts such as cogwheels and cams because it is moves the lens directly with the polymer actuator. Moreover, because the actuator can be set up in the space, the lens unit can be greatly reduced to the size.

The polarity of the actuator was reversed, and piled them up. The vertical movement stroke can be efficiently taken out by an appropriate piling. It is possible to apply it also to vertical movements other than the zoom mechanism. | ||

3.Medical device (catheter, guide wire, others) |
A tube actuator is applied to the catheter tip of 1mm diameter,and the actuator tip can be bent in all directions under outside control of the body by the electric lead wire. In interventional radiology, reaching the diseased part after the blood vessel is selected, doing packing of the artery, and doing concentrated administering etc. of anti-cancer drug easily and safely become possible.

4.Hobby |
It is the artificial fish which sails in the tail fillet made with the actuator element.
Electric power is supplied to the coil in an artificial fish by the electromagnetic induction
from a tank. It can swim a long term without a maintenance.
