  • Publication number: 20150012230
    Abstract: This invention is a novel methodology for precision metrology, sensing, and actuation at the micro- and nano-scale. It is well-suited for micro- and nano-scale because it leverages off the electromechanical benefits of the scale. The invention makes use of electrical measurands of micro- or nano-scale devices to measure and characterize themselves, other devices, and whatever the devices subsequently interact with. By electronically measuring the change in capacitance, change in voltage, and/or resonance frequency of one or more test structures, a multitude of geometric, dynamic, and material properties may be extracted with a much higher accuracy and precision than conventional methods.

  • Publication number: 20120168233
    Abstract: A robot and method of manufacturing the same are disclosed. Embodiments of the robot include robots with piezoelectric appendages and microrobots of very small sizes, for example, robots with appendage lengths equal to approximately 300 ?m. Further embodiments include a plurality of piezoelectric appendages, each appendage including a plurality of piezoelectric members coupled to one another at two locations, while other embodiments include appendages with piezoelectric members coupled to one another at three locations. Various embodiments are capable of jumping, walking upside down, carrying heavy loads, and/or walking with foreign object contamination in one or more appendages. Still further embodiments include energy storage members that store the energy generated by an appendage when the appendage is subject to external forces.

  • Patent number: 8166796
    Abstract: A self-calibrating apparatus comprises a primary device and a test structure fabricated on an integrated circuit chip. The primary device and the test structure have at least one unknown property due to a fabrication process of the integrated circuit chip. An electrical measurand sensor is configured to measure an electrical measurand of the test structure. A controller coupled to the primary device and electrical measurand sensor. The controller is configured to calculate the at least one unknown property of the test structure based on the measured electrical measurand and use the calculated at least one unknown property to calibrate the primary device.

  • Publication number: 20110025350
    Abstract: This invention is a novel methodology for precision metrology, sensing, and actuation at the micro- and nano-scale. It is well-suited for tiny technology because it leverages off the electromechanical benefits of the scale. The invention makes use of electrical measurands of micro- or nano-scale devices to measure and characterize themselves, other devices, and whatever the devices subsequently interact with. By electronically measuring the change in capacitance, change in voltage, and/or resonant frequency of just a few simple test structures, a multitude of geometric, dynamic, and material properties may be extracted with a much higher precision than conventional methods.

  • Publication number: 20080100175
    Abstract: The present invention relates to MicroElectroMechanical Systems (MEMS), devices and applications thereof in which a proof mass is caused to levitate by electrostatic repulsion. Configurations of electrodes are described that result in self-stabilized floating of the proof mass. The electrical properties of the electrodes causing floating, such as currents and/or voltages, typically change in response to environmental perturbations affecting the proof mass. Measuring such currents and/or voltages allow immediate and accurate measurements to be performed related to those perturbations affecting the location and/or the orientation of the proof mass. Additional sensing electrodes can be included to further enhance sensing capabilities. Drive electrodes can also be included that allow forces to be applied to the charged proof mass resulting in a floating, electrically controllable MEMS device.
