  • Patent number: 11229125
    Abstract: A system for controlled motion of circuit components to create reconfigurable circuits comprising: a support; a substrate operatively associated with the support; actuators operatively associated with the support configured to physically move circuit components and to move the circuit components into physical and electrical contact with the substrate; the substrate comprising at least one conductive segment arranged to electrically connect circuit components when electrical contacts of circuit components are placed in contact with at least one conductive segment; and control circuitry configured to control the first and second actuators to thereby position the circuit components relative to the substrate; whereby circuit function is determined by the selection of circuit components and the location and orientation of circuit components relative to the substrate and conductive segments to create a reconfigurable circuit.
    Type: Grant

  • Patent number: 7944121
    Abstract: Co-fabricating of vertical piezoelectric MEMS actuators that achieve large positive and negative displacements through operating electric fields in excess of the coercive field includes forming a large negative displacement vertical piezoelectric MEMS actuator, forming a bottom structural dielectric layer above a substrate layer; forming a bottom electrode layer above the structural dielectric layer; forming an active piezoelectric layer above the bottom electrode layer; forming a top electrode layer above the active piezoelectric layer; forming a top structural layer above the top electrode layer, wherein the x-y neutral plane of the negative displacement vertical piezoelectric MEMS actuator is above the mid-plane of the active piezoelectric layer, wherein the negative displacement vertical piezoelectric MEMS actuator is partially released from the substrate to allow free motion of the actuator; and combining the large negative displacement vertical piezoelectric MEMS actuator and a large positive displaceme
