A Bioinspired Tilt Sensor Model with Adaptive Gain and Enhanced Sensitivity

摘要: Although various types of tilt sensors have been proposed in the past decade, it is still essential to develop rugged, cheap, simple-structured with wide measuring range and high sensitivities for efficient monitoring infrastructures early warning natural disasters. It has investigated that stereocilia some fishes’ inner ear organs are basic sensory units nature’s inertial highly sensitive over broad dynamic because a combination adaptation negative stiffness mechanisms. In this paper, bioinspired sensor model mimics mechanism adaptive signal amplification mechanical stimuli, leading sensitivity weak input low input, thus expanding through amplification. The implemented by magnet forces. motion measured strain gauge at end flexible cantilever beam element model. Measurements both static dynamics investigated. Numerical simulation results used demonstrate capability measurements motions enhanced sensitivity.
