摘要： A micro-machined magnetic latching relay has a moveable cantilever comprising a soft magnetic material and having a first end and a second end. The cantilever has a rotational axis which is a flexure supported by a substrate. A first permanent and a second permanent magnet are disposed near the first end and the second end of the cantilever respectively. Each of the two magnets produces a magnetic force and a torque on the cantilever. The first permanent magnet, second permanent magnet and the substrate are arranged to provide two stable positions for the cantilever. An electromagnet provides a temporary switching magnetic field to adjust the local magnetizations across the magnetic cantilever, causing changes of magnetic forces and torques on the cantilever. As a result, the direction of a sum of torque on the cantilever is reversed. Therefore, the cantilever is switched from one stable position to the other.

摘要： A micro-machined magnetic relay has a moveable cantilever comprising a soft magnetic material and having a first end and a second end. The cantilever has a rotational axis which is a flexure supported by a substrate. The cantilever has a first state and a second state. A first permanent magnet is disposed near the first end of the cantilever to force the cantilever in the first state. A second movable magnet causes changes of magnetic forces and torques on the cantilever. Therefore, the direction of a sum of torque on the cantilever is reversed. As a result, the cantilever flips from the first state to the second state. The relay can be used as a proximity sensor to detect the motion of an object associated with the second movable magnet.

摘要： A micro magnetic latching device. The device comprises a substrate having a moveable element supported thereon. The moveable element (cantilever) has a long axis and a magnetic material. The device also has first and second magnets that produce a first magnetic field, which induces a magnetization in the magnetic material. The magnetization is characterized by a magnetization vector pointing in a direction along the long axis of the moveable element, wherein the first magnetic field is approximately perpendicular to a major central portion of the long axis. The device also has a coil that produces a second magnetic field to switch the movable element between two stable states, wherein only temporary application of the second magnetic field is required to change direction of the magnetization vector thereby causing the movable element to switch between the two stable states.

摘要： A micro-machined radio frequency (RF) switch is described. The micro-machined RF switch includes a substrate, a moveable micro-machined cantilever supported by the substrate, and an actuation mechanism that causes the cantilever to switch between two or more states. In a first state, a conducting layer of the cantilever couples a RF transmission line to a reference signal. In a second state, the conducting layer does not couple the RF transmission line to the reference signal. In further states, the conducting layer can couple one or more additional RF transmission lines to respective reference signals. A portion of the cantilever can flex or be angled to enhance coupling of an RF transmission line to a reference signal.

摘要： A micro-machined magnetic latching switch is described. A moveable micro-machined cantilever has a magnetic material and a longitudinal axis. The cantilever has a conducting layer. A permanent magnet produces a first magnetic field, which induces a magnetization in the magnetic material. The magnetization is characterized by a magnetization vector pointing in a direction along the longitudinal axis of the cantilever. The first magnetic field is approximately perpendicular to longitudinal axis. A three-dimensional solenoid coil produces a second magnetic field to switch the cantilever between a first stable state and a second stable state. The temporary current is input to the three-dimensional solenoid coil, producing the second magnetic field such that a component of the second magnetic field parallel to the longitudinal axis changes direction of the magnetization vector. The cantilever is thereby caused to switch between the first stable state and the second stable state.
