With a total of 3 patents to his name, Siekkinen has made strides in developing innovative solutions that enhance the functionality and reliability of pressure sensors.

Latest Patents

One of Siekkinen's latest patents is the all-silicon capacitive pressure sensor. This invention features a monolithic capacitive absolute pressure-sensing device that utilizes a single-crystal silicon diaphragm as a flexible capacitor plate. The diaphragm is bonded to a silicon wafer, which has a cavity etched into it. The design includes a fixed capacitor plate formed by a heavily-doped region at the bottom of the cavity, with a thin dielectric layer completing the capacitor. This innovative design allows for overpressure protection and produces a capacitive output signal based on changes in contact area in response to applied pressure.

Another significant patent by Siekkinen is a method of detecting low tire pressure by comparing wheel speeds. This method involves measuring the relative speeds of wheels in various speed ranges when tires are properly inflated. By learning offsets due to parameters unrelated to pressure, the system can monitor for abnormal wheel speed patterns indicative of pressure drops. The method allows for high sensitivity monitoring after learning periods, ensuring timely warnings for significant pressure drops.
