Resonant mems sensors for detecting contact forces and conditions
The patent application (Publication Number: US20240011854A1) describes a device comprising one or more microelectromechanical systems (MEMS) resonators mounted near a surface to detect forces applied to the surface. These resonators produce electronic signals representing different orientations of a resonance mode axis 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 MEMS resonators can be calibrated to correct for frequency drift over time, ensuring accurate readings.
Furthermore, the device can include multiple resonators with varying mass differences, allowing for structural differences to enhance performance. The circuitry in the device stores baseline frequencies for each signal, identifies frequency deviations, and calculates the force direction based on these deviations. Additionally, a timing signal generator can be used to detect frequency deviations and determine the force direction accurately. Overall, the device offers a sophisticated system for detecting and analyzing forces applied to a surface, with the ability to calibrate and normalize readings for improved accuracy and reliability.
