Latest Patents
W Thomas Pike holds a patent for a silicon micromachined accelerometer/seismometer. This invention features a silicon-based microaccelerometer designed for seismic applications. It utilizes a low-resonant frequency of 10 Hz, a large proof mass of 1 gram, and a high Q suspension to achieve high sensitivity of less than 1 ng with a bandwidth of 0.05 to 50 Hz. The proof mass is intricately cut from a planar substrate in the form of a disk, which closely fits but does not touch a surrounding angular frame. The spring mechanism of the microaccelerometer is created from two continuous, 3-micron thick membranes. The design includes fixed capacitive electrodes on separate, subsequently bonded substrates, while movable capacitive plates are located on the membranes. This configuration allows for precise control of the gap between the fixed and movable capacitive plates in the differential capacitive sensor. The use of continuous membranes for the spring results in a shock-resistant and robust sensor.
