    Abstract

    We present a model for our cricket-inspired, biomimetic, artificial hair sensors, to analyze the sensitivity dependence on structural and geometrical parameters. Based on this model, feasible design improvements to achieve an increased sensitivity are discussed and a figure of merit to evaluate sensor performance is defined. Also, we discuss the results of a novel approach to implement adaptive sensor arrays through DC-biasing based on the electrostatic spring-softening effect. Experimental results show a clear theoreti¬cal accordance and tunability of system’s resonance frequency, providing opportunities for frequency focusing and selective sensitivity.
