Abstract:
PURPOSE: An actuator used in a micro electro mechanical system, and tweezers and a switch utilizing the same are provided to reduce power consumption, to improve an operational speed and to easily fabricate the actuator by fabricating each beam of the actuator with the same material. CONSTITUTION: An actuator used in a micro electro mechanical system(100) includes a pair of beams(110,120), which are made of the same material. Lengths of the beams(110,120) are different from each other. The beams(110,120) are parallel aligned to each other. The beams(110,120) are made of metal having a predetermined thermal coefficient, such as copper. Upper ends of the beams(110,120) are fixed to each other by means of a fixing section(130). The fixing section(130) is integrally formed with the beams(110,120). A pair of power supplying terminals(111,121) is formed at a lower end of the beams(110,120).
Abstract:
An actuator in serial multi-interconnection is provided to control the increase degree of a total driving distance by differently setting the driving distance of each micro actuator. In an actuator in serial multi-interconnection, micro actuators(110,120) include elastic bodies(111,121), displacement generators(113,123), and mass bodies(112,122). The elastic bodies are connected to the micro actuators at a fixed end or a front end. The displacement generators deform the elastic bodies as much as individual driving distances. The mass bodies are moved by the distance generator as much as the individual driving distances, and return to origin positions by the elastic bodies.

CONSTITUTION: A micro driver(100) includes two drive amplifying bars(111,112), two driven bars(121,122) and five rotating articulated units(151,152,161,162,17). The driven bars(121,122) are connected to each other by means of a rotating articulated unit(17). The drive amplifying bars(111,112) are rotatably connected to the other end of the driven bars(121,122) through the rotating articulated units(161,162). The drive amplifying bars(111,112) are arranged parallel to each other while forming a predetermined interval. Free ends of the drive amplifying bars(111,112) are rotatably fixed to a substrate by means of rotating articulated units(151,152).
Abstract:
PURPOSE: A method for encapsulating microelectromechanical(MEMS) structures is provided which the MEMS structures are formed on a substrate and encapsulated prior to packaging thereof. CONSTITUTION: A MEMS microrelay(200) is typically formed on a substrate(210) and comprises, for example, an active actuator(220), a relay structure(230), and a passive actuator(240). In some cases, the structures forming the microrelay further include associated bond pads(250) at which the necessary electrical connections to the structures are established.The bonding pads forms electrical contact points providing the necessary electrical power for the active actuator or the connections to the relay structure. Typically, the operation of a MEMS device, such as the MEMS microrelay described, requires mechanical motion of components of the microrelay for the device to operate as intended.
