The micromirror device can drive the mirror in two directions and adjust a rotational angle of the mirror using the electrostatic force due to a potential difference between the electrodes and the mirror for reflecting incident light, and the elastic restoring force of the cantilevers.

    Abstract: Disclosed is an electrostatic actuator. A multi-layered auxiliary electrode is further arranged between main electrode and actuating body, and positive charge or negative charge is applied to main electrode, respective auxiliary electrodes, and actuating body such that electrostatic attractive force is generated between auxiliary electrodes adjacent to the main electrode, between adjacent auxiliary electrodes, and between auxiliary electrodes adjacent to the actuating body. According to the invention, distance between the induced charges is shortened, so that electrostatic attractive force therebetween increases, thereby capable of maintaining an actuating range equal to or larger than the conventional electrostatic actuator. The electrostatic actuator according to the present invention can be applied to various MEMS devices, such as an optical switch in which a mirror is formed in the actuator, a radio frequency (RF) switch, or a variable electrostatic capacitor, or the like.

    Abstract: The present invention relates to a micropump which is driven by movement of a liquid drop based upon continuous electrowetting actuation. The continuous electrowetting means a phenomenon that the liquid drop moves as the surface tension of the liquid drop is electrically varied in succession. When a tube in which electrolyte and a liquid metal drop are inserted is applied with voltage having periodically changing polarity via metal electrodes, the surface tension of the liquid metal is varied so that the liquid metal drop reciprocates in the tube generating pressure or force, which is used as a driving force of the micropump. The micropump is operated in a low voltage and consumes a small amount of electric power.

    Abstract: A method of fabricating a refractive silicon microlens by using micro-machining technology. The method of fabricating a refractive silicon microlens according to the present invention comprises the steps of forming a boron-doped region on a silicon substrate, and selectively removing regions of the substrate except for the boron-doped region to form a lens comprised of only the boron-doped region. With the method of the present invention, it is possible to fabricate a two-dimensional infrared silicon microlens array. By using such a two-dimensional infrared silicon microlens array in an infrared sensor, the detectivity of the infrared sensor can be increased by 3.4 times, which is the refraction index of silicon. In addition, the two-dimensional infrared silicon microlens array of the present invention can be used with commercial infrared telecommunication devices.
