摘要： A thermal microactuator is provided that can be deflected in multiple positions. The actuator has a hot arm and a cold arm coupled together at their distal ends suspended above a reference plane of a substrate. A potential difference is applied across the hot arm so that a current circulates through the hot arm but not the cold arm.

摘要： A microelectromechanical relay and a method of fabricating the same that combines electrostatic actuation with electromagnetic actuation. The relay has very low contact resistance when the relay is in its ON state and enhanced contact-to-contact isolation when the relay is in its OFF state. The relay includes a substrate having a trench formed therein, a first pair of contacts located in the trench and an actuator for controllably establishing electrical contact between the first pair of contacts. The actuator includes spaced apart supports on the substrate and a movable beam extending between the supports. A contact cross bar is located on the movable beam facing the first pair of contacts. A first electrode is located on the movable beam and a second electrode is located on the substrate. Electromagnetic force is used to deflect the movable beam towards the substrate and then electrostatic force is used to bring the contact cross bar in physical contact with the first pair of contacts.

摘要： A wireless resonant micro-actuator for untethered micro-robots. The wireless resonant micro-actuator includes at least two magnetic bodies that are resiliently connected to one another by a resilient member to form a spring-mass system. A magnetic field generator generates a pulsating or oscillating external magnetic field that creates a magnetic force between the at least two magnetic bodies. The at least two magnetic bodies are capable of being mechanically oscillated to resonance with respect to one another. A converter converts the oscillatory motion of the at least two magnetic bodies to create useful motion.

摘要： The invention concerns a novel magnetic actuator mechanism suitable for use on untethered microrobots. It relies on the interaction of magnetic bodies in an external magnetic field. By an oscillating field, the bodies are driven to oscillatory motion, and the energy stored in the oscillation is harnessed. The untethered wireless microactuator according to the invention comprises a mechanical system with at least two magnetic bodies resiliently connected to one another, wherein the mechanical system is capable of being oscillated, in particular driven to resonance, by an oscillating external magnetic field. The actuation system according to the invention comprises such a microrobot as well as a magnetic field generator with adjustable field direction and oscillation frequency. The actuation method comprises exciting two or more magnetic bodies with an oscillating magnetic field such that they perform mechanical oscillations, and harnessing this energy for propulsion of the device or to fulfill other tasks.
