摘要： A microelectromechanical device, in particular a non-volatile memory module or a relay, comprising: a mobile body including a top region and a bottom region; top electrodes facing the top region; and bottom electrodes, facing the bottom region. The mobile body is, in a resting condition, at a distance from the electrodes. The latter can be biased for generating a movement of the mobile body for causing a direct contact of the top region with the top electrodes and, in a different operating condition, a direct contact of the bottom region with the bottom electrodes. In the absence of biasing, molecular-attraction forces maintain in stable mutual contact the top region and the top electrodes or, alternatively, the bottom region and the bottom electrodes.

摘要： Micro-electromagnetically actuated latched miniature relay switches formed from laminate layers comprising a spring and magnet, electromagnetic coils, magnetic latching material, and transmission line with contacts. Preferably the miniature relay switches transmit up to about 50 W of DC or AC line power, and carry up to about 10 A of load current, with an overall volume of less than about 100 mm3. In addition to switching large power, the device preferably requires less than 3 V to actuate, and has a latching feature that retains the switch state after actuation without the need for external applied voltage or current.

摘要： A micro electromechanical (MEMS) switch suitable for use in medical devices is provided, along with methods of producing and using MEMS switches. In one aspect, a micro electromechanical switch including a moveable member configured to electrically cooperate with a receiving terminal is formed on a substrate. The moveable member and the receiving terminal each include an insulating layer proximate to the substrate and a conducting layer proximate to the insulating layer opposite the substrate. In various embodiments, the conducting layers of the moveable member and/or receiving terminal include a protruding region that extends outward from the substrate to switchably couple the conducting layers of the moveable member and the receiving terminal to thereby form a switch. The switch may be actuated using, for example, electrostatic energy.

摘要： A latching relay employing a movable cantilever with a first permanent magnet and a nearby second magnet is disclosed. The permanent magnet affixed to the cantilever is permanently magnetized along its long (horizontal) axis. The cantilever has a first end associated to the first pole (e.g., north pole) of the first magnet, and a second end associated to the second pole (e.g., south pole) of the first magnet. When the first end of the cantilever approaches the second magnet, the first pole of the first magnet induces a local opposite pole (e.g., south pole) in the second magnet and causes the first end of the cantilever to be attracted to the local opposite pole of the second magnet, closing an electrical conduction path (closed state). An open state on the first end of cantilever 10 can be maintained either by the second pole of first magnet being attracted to a local opposite pole in the second magnet or by a mechanical restoring force of flexure spring which supports the cantilever. A third electromagnet (e.g., a coil or solenoid), when energized, provides a third perpendicular magnetic field about the first magnet and produces a torque on the associated cantilever to force the cantilever to switch between closed and open states. A few alternate embodiments of the relay are also disclosed which include a case where the latching feature is disabled, and another case where an external magnet is used to switch the cantilever.

摘要： A substantially straight beam in an unbuckled state is compressed to cause the beam to buckle using an adjustable compressor. The adjustable compressor applies force to one or both ends of the beam and limits compression on the beam to allow the beam to move between a first buckled state and a second buckled state. The first buckled state and the second buckled state comprise substantially equal magnitude and opposite direction buckling movements from the unbuckled state.

The method can include providing a stationary electrode and a stationary contact formed on a substrate. Further, a movable microcomponent suspended above the substrate can be provided. A voltage can be applied between the between a movable electrode of the microcomponent and the stationary electrode to electrostatically couple the movable electrode with the stationary electrode, whereby the movable component is deflected toward the substrate and a movable contact moves into contact with the stationary contact to permit an electrical signal to pass through the movable and stationary contacts. A current can be applied through the first electrothermal component to produce heating for generating force for moving the microcomponent.
