Directional force sensor using coordinated mems resonators
A recently granted patent (Publication Number: US12000748B2) discloses a device comprising one or more microelectromechanical systems (MEMS) resonators mounted near a surface to detect forces. These resonators produce electronic signals representing different orientations of resonance mode axes relative to the force direction. The device includes circuitry to receive these signals and generate a signal indicating the force direction relative to the surface. The device can have multiple resonators, each providing unique resonance mode orientations, allowing for accurate force detection.
Furthermore, the device includes calibration circuitry to identify and correct frequency drift over time, ensuring accurate readings. The circuitry can store calibration information in the form of polynomials to normalize resonator outputs. Additionally, the device can have resonators with post-formation mass differences, enabling structural variations for enhanced functionality. The circuitry utilizes baseline frequencies and timing signals to calculate force direction based on frequency deviations. Overall, this patented device offers a sophisticated system for detecting forces accurately and efficiently, with applications in various fields requiring precise force measurements.
