摘要： A linear actuator capable of inducing a linear motion as well as a rotational motion using only two rotors is provided. The linear actuator includes: first and second rotors connected to respective driving force sources; a linear motion unit formed on the first rotor to be linearly movable; and a driving power transmission unit which is fixed to the second rotor and engages the linear motion unit. A linear motion on a rotor can be easily induced using a relative angular velocity difference between two rotors without an additional driving power source for the linear motion.

摘要： A vertical comb actuator radio frequency (RF) micro-electro-mechanical system (MEMS) switch. The RF MEMS switch includes a substrate; first and second signal lines spaced at a predetermined interval from each other and deposited on an upper surface of the substrate; an actuator positioned over the first and second signal lines when viewed from the upper surface of the substrate and spaced at a predetermined interval from the first and second signal lines; and a fixing portion positioned over the actuator when viewed from the upper surface of the substrate, wherein the fixing portion permits the actuator to come in contact with the first and second signal lines when a predetermined driving voltage is applied. Thus, it is possible to prevent the actuator from sticking to the substrate. In addition, the RF MEMS switch can be operated with a low voltage and insertion loss and power loss can be reduced.

摘要： A MEMS (Micro Electro Mechanical Systems) switch actuated by electrostatic and piezoelectric forces, includes a substrate; a first contact point positioned in a predetermined first area on an upper surface of the substrate; a support layer suspended at a predetermined distance from the upper surface of the substrate; a second contact point formed on a lower surface of the support layer; a first actuator operative to move the support layer in a predetermined direction using an electrostatic force; and a second actuator operative to move the support layer in a predetermined direction using a piezoelectric force. The first actuator is used to turn on the MEMS switch. The second actuator can be used together with the first actuator to turn on the MEMS switch or can be separately used to turn off the MEMS switch. As a result, a stiction can be prevented from occurring between contact points.

摘要： A rotation-type decoupled MEMS gyroscope including a drive body movable about the X-axis, a sensing body movable about the Z-axis, a medium body moving together with the drive body about the X-axis and the sensing body about the Z-axis. The drive body is fixed on a substrate by a first torsion spring torsion-deformed about the X-axis, and the medium body is connected to the drive body by a first bending spring bending-deformed about the Z-axis. The sensing body is connected to the medium body by a second torsion spring torsion-deformed about the X-axis and fixed to the substrate by a second bending spring bending-deformed about the Z-axis. If angular velocity is applied relative to the Y-axis while the drive body vibrates in a certain range about the X-axis by a driving electrode, the sensing body rotates about the Z-axis by the Coriolis force and a sensing electrode senses the rotation.
