    Abstract: A device, such as a switch structure, is provided, the device including a contact and a conductive element. The conductive element can be configured to be selectively moveable between a non-contacting position, in which the conductive element is separated from the contact (in some cases by a distance less than or equal to about 4 μm, and in others by less than or equal to about 1 μm), and a contacting position, in which the conductive element contacts and establishes electrical communication with the contact. When the conductive element is disposed in the non-contacting position, the contact and the conductive element can be configured to support an electric field therebetween with a magnitude of greater than 320 V μm−1 and/or a potential difference of about 330 V or more.

    Abstract: A system that includes micro-electromechanical system switching circuitry, such as may be made up of a plurality of micro-electromechanical switches, is provided. The plurality of micro-electromechanical switches may generally operate in a closed switching condition during system operation. A controller is coupled to the electromechanical switching circuitry. The controller may be configured to actuate at least one of the micro-electromechanical switches to a temporary open switching condition while a remainder of micro-electromechanical switches remains in the closed switching condition to conduct a load current and avoid interrupting system operation. The temporary open switching condition of the switch is useful to avoid a tendency of switch contacts to stick to one another.

    Abstract: A gating voltage control system and method are provided for electrostatically actuating a micro-electromechanical systems (MEMS) device, e.g., a MEMS switch. The device may comprise an electrostatically responsive actuator movable through a gap for actuating the device to a respective actuating condition corresponding to one of a first actuating condition (e.g., a closed switching condition) and a second actuating condition (e.g., an open switching condition). The gating voltage control system may comprise a drive circuit electrically coupled to a gate terminal of the device to apply a gating voltage. The gating voltage control system may further comprise a controller electrically coupled to the drive circuit to control the gating voltage applied to the gating terminal in accordance with a gating voltage control sequence. The gating voltage control sequence may comprise a first interval for ramping up the gating voltage to a voltage level for producing an electrostatic force sufficient to accelerate the actuator through a portion of the gap to be traversed by the actuator to reach a respective actuating condition. The gating voltage control sequence may further comprise a second interval for ramping down the gating voltage to a level sufficient to reduce the electrostatic force acting on the movable actuator. This allows reducing the amount of force at which the actuator engages a contact for establishing the first actuating condition, or avoiding an overshoot position of the actuator while reaching the second actuating condition.
