| Research Abstract |
In order to develop optical actuators for driving micromachines, following studies have been carried out.
1)The photothermal vibration for shape-memory alloys was investigated. The amplitude was very large compared with the other conventional materials. The temperature characteristic of alloy was measured.
2)The optical vibrator using shape-memory alloy and bias spring was developed. The displacement of 3 mm and the generation force 2N were obtained with irradiation of laser power of 300mW.A miniature water flow pump was driven with this actuator.
3)The photothermal rotation of a cantilver around z-axis was investigated. The cantilever was irraditaed with two laserrs of which phases were differentiall by 90 dgree.
4)The micro-pincette was constructed from two flat optical fiber cables. A clad layr was eliminated from the fiber-tip, and a microcantilever was fabricated. Using these two cantilver, a sphere of 0.1 mm was gripped in liquid.
5)The micro-grippeer was developed. Several shape-memory wires were set up around the optical fiver. A sphere with a weight of 50g-w was gripped with irradiation laser power of 100mW.
6)Several optical sensors were developed using the mechanical vibration of the laser-driven microcantilever fabricated from the optical fiber-tip.
