Latest Patents

Among his latest patents is the "Integrated Electrostatically-Actuated Micromachined All-Metal Relay." This invention describes structures and fabrication methods for micromachined all-metal relays on silicon chips. The relay features a copper blade electroformed into lithographically patterned areas, with dimensions of 1 mm × 2 mm × 0.01 mm (width × length × thickness) and includes longitudinal slots to facilitate the fabrication process. Notably, the relay is actuated by electrostatic force, eliminating the need for conduction current to maintain either the 'on' or 'off' state. It is ideally used in conjunction with a suitable arc suppression circuit.

Another significant patent is the "Active Microaccelerometer," designed for on-board automotive safety control and navigational systems. This microaccelerometer consists of a central support body supported on a backing chip, with a peripheral proof mass surrounding it. The design includes at least one pair of microbridges that connect the central support body to the peripheral proof mass, allowing for precise measurement of acceleration. Piezoelectric drivers and sensors are integrated to excite the microbridges at their resonant frequencies and detect changes in these frequencies, ensuring accurate performance.
