Latest Patents

Dunfield holds a patent for a resonant micromachined biochemical sensor. This sensor system is formed from a micro machined resonant structure with multiple resonant elements, tracking resonator control electronics, and signal processing algorithms. The moving elements of the resonator are coated with chemically active materials that change mass when exposed to the target chemical, resulting in a change in frequency or period of oscillation. The changes in frequency or period are processed by multi-sensor chemical detection algorithms to identify chemical types and concentrations. Essentially, the resonator and drive electronics form a closed loop oscillator operating at the resonator's natural frequency. The resonators are formed from silicon using photolithographic processes, and the design includes in-plane resonant motion combined with dynamic balance to operate with a high Q even in the presence of atmospheric pressure. He has 1 patent to his name.
