Abstract: 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.

Abstract: Frequency addressable micro-actuators having one or more movable resonating elements actuators, such as cantilevers, can be forced into oscillation by, e.g., electromagnetic actuation. The movable structure is designed to latch at a certain amplitude using one of several latching techniques, such as a near-field magnetic field. In operation, the movable element is driven into resonance, producing a large amplitude, which results in the structure latching. Through resonance, a small force applied in a repeating manner can result in the latching of the actuator, an operation which would normally require a large force. If two or more units, each with different harmonic frequencies, are placed under the same influence, only the one with a harmonic response to the driving force will latch. A single influencing signal may be used to latch more than one device on demand by tuning the frequency to match the natural frequency of the device of interest.

Abstract: Micro capacitive switches and methods of manufacturing micro capacitive switches at variable nominal capacitance value using micro-structures on the contact plates of the same dimension. In a preferred embodiment, a separately manufactured contact plate can be mounted to a movable magnet in order to be actuated to “on” and “off” state of the capacitive switch. Depending on the contact plate's surface condition, variable contact capacitance at “on” state can be precisely specified by geometrical properties of the micro-structures on the surface, such as the density, size and depth.
