    摘要: The present invention provides a bi-directional microelectromechanical element, a microelectromechanical switch including the bi-directional element, and a method to reduce mechanical creep in the bi-directional element. In one embodiment, the bi-directional microelectromechanical element includes a cold beam having a free end and a first end connected to a cold beam anchor. The cold beam anchor is attached to a substrate. A first beam pair is coupled to the cold beam by a free end tether and is configured to elongate when heated thereby to a greater temperature than a temperature of the cold beam. A second beam pair is located on an opposing side of the cold beam from the first beam pair and is coupled to the first beam pair and the cold beam by the free end tether. The second beam pair is configured to elongate when heated thereby to the greater temperature.

    摘要: A micromechanical actuator includes a movable first spring element having metal and/or silicon. The first spring element is fitted at a first point and can move freely at a second point. A second spring element connected to the first spring element has silicon and is partially arranged on an electrically insulating material which is applied to a substrate. The second spring element is arranged at a distance from the substrate above the substrate on a first plane, and the first spring element is arranged above the second spring element on a second plane which is at a distance from the first plane such that the first and second spring elements can move with respect to the substrate. The actuator has a third spring element which is mechanically coupled to the first spring element. The elastic deformation of the second spring element can be induced by a length change of the third spring element.

    摘要: The present invention provides an electromechanical switch enabled to achieve a high-speed switching response at a low driving voltage. An electromechanical switch body 10, which is an MEMS switch, has a first movable electrode 14 and a second movable electrode 16, both ends of each of which are respectively fixed to and laid on a first anchor 12 and a second anchor 13 formed on a silicon substrate 2, and also has a fixed electrode 18 that faces these movable electrodes. A first electromechanical switch 22 enabled to be driven at a low voltage is constituted by the first movable electrode 14, which has a relatively weak spring force, and the fixed electrode 18. A second electromechanical switch 24 enabled to be latched at a low voltage is constituted by the second movable electrode 16, which has a relatively strong spring force, and the fixed electrode 18. Consequently, the first movable electrode 14 is displaced at high speed at a low driving voltage, so that the first electromechanical switch is turned on at high speed. A restoring force causes the second movable electrode 16 to perform natural vibrations at high speed, so that the second electromechanical switch is turned off at high speed. The restored second movable electrode 16 is latched at a low driving voltage, so that the second electromechanical switch is turned on.

    摘要: A MEMS switch includes a lower substrate having a signal line on an upper surface of the lower substrate; an upper substrate, having a cavity therein, disposed apart from the upper surface of the lower substrate by a distance, and having a membrane layer on a lower surface of the upper substrate; a bimetal layer formed in the cavity of the upper substrate on the membrane layer; a heating layer formed on a lower surface of the membrane layer; and a contact member formed on a lower surface of the heating layer. The contact member can come into contact with or separate from the signal line. A method for manufacturing the MEMS switch includes preparing the upper and lower substrates and combining them so that a surface having the signal line faces a surface having the contact member and the upper and lower substrates are disposed apart by a distance.

    摘要: A MEMS hysteretic thermal actuator may have a plurality of beams disposed over a heating element formed on the surface of the substrate. The plurality of beams may be coupled to a passive beam which is not disposed over the heating element. One of the plurality of beams may be formed in a first plane parallel to the substrate, whereas another of the plurality of beams may be formed in a second plane closer to the surface of the substrate. When the heating element is activated, it heats the plurality of beams such that they move the passive beam in a trajectory that is neither parallel to nor perpendicular to the surface of the substrate. When the beams are cooled, they may move in a different trajectory, approaching the substrate before moving laterally across it to their initial positions. By providing one electrical contact on the distal end of the passive beam and another stationary electrical contact on the substrate surface, the MEMS hysteretic actuator may form a reliable electrical switch that is relatively simple to manufacture and operate.
