MEMS Reservoir Computing using Frequency Modulated Accelerometer

 For miniaturization and Intelligence of MEMS sensors, we are developing resonant accelerometers that can learn and classify acceleration signal patterns using reservoir computing, which can use the micro-vibration of beams as a computational resource. In this research, we propose a device that changes the stiffness of a vibrating beam as a state change of the reservoir, and evaluate its learning performance.
