Mems vibration sensor suspension with integrally extending springs
The patent US12072350B2 presents a novel suspension system for microelectromechanical systems (MEMS) vibration sensors. The core of the invention comprises multiple anchor assemblies, each featuring an anchor body and integrally extending springs. These springs are designed with a complex structure that includes multiple sections, lateral portions, and legs, allowing for enhanced mechanical performance. The design ensures that the second ends of the springs extend further from the anchor body than the first lateral portions, facilitating the connection of a proof mass. This proof mass is integral to the sensor's functionality, as it is connected to the second legs of the anchor assemblies, which are aligned along a connection axis.
Further claims detail the configuration of the proof mass, which can be a plate of material, and its relationship with the anchor assemblies. The design allows for lateral offsets from the edges of the proof mass, optimizing the sensor's resonance frequencies for various modes of vibration. The patent also describes arrangements involving multiple proof masses and support plates, enhancing the sensor's capabilities. The integration of fixed electrodes to adjust resonance frequencies through applied bias voltage is also highlighted, indicating a sophisticated approach to tuning the sensor's performance. Overall, the claims outline a comprehensive and intricate suspension system aimed at improving the sensitivity and accuracy of MEMS vibration sensors.
