The absolute displacement measurement of vibrating platforms/objects is always needed in vibration control and signal processing. In this work, inspired by recent practical requirement of engineering applications, we propose a novel bio-inspired dynamics vibration sensor system for absolute vibration displacement measurement. Without using any sophisticated and complex structure, the proposed sensor system can be accomplished by simple beams and springs. The theoretic analysis of the bio-inspired sensor system indicates a possible way in achieving nonlinear quasi-zero stiffness and consequently creating a broadband vibration-free point for absolute displacement measurement, and thus realizing an outstanding measurement performance. Importantly, the square-root unscented Kalman filter (SR-UKF) technique for dynamic state estimation of the bio-inspired dynamic sensor is developed to avoid the drawback of measurement noises from the sensor data, which improves the accuracy of the resulting vibration measurement. Experiments verified the effectiveness of this novel sensor system.
