Latest Patents

Among his latest patents is the "Anodically Bonded Strain Isolator." This invention allows a sensor to be attached to materials with the same coefficient of thermal expansion while providing the necessary elastic isolation between the sensor and the system it is mounted on. The isolator is constructed from borosilicate glass and silicon, with the glass matching the mounting surface of MEMS sensors. The silicon serves as an excellent isolator due to its elasticity and ability to be formed into complex shapes. The anodic bonding technique used in this construction can be tailored to different types of MEMS sensors, optimizing their geometry to minimize overall volume.

Another notable patent is the "Bidirectional, Out-of-Plane, Comb Drive Accelerometer." This bi-directional electrostatic comb drive apparatus features two electrically independent sets of stator comb tines. The design includes a method for fabricating an out-of-plane comb drive with stacked sets of stator comb tines. The first set of stator comb tines is offset from the second, allowing for independent operation. By applying different voltages to each set, the rotor tines can be pulled toward either set, enabling bi-directional functionality.
