Abstract

We report improvements in detection limit and responsivity of biomimetic hair flow sensors by electrostatic spring-softening (ESS). Applying a DC voltage to our capacitive flow sensors results in a reduced sensory threshold, which gives an improvement for the flow detection limit of more than 30%. In addition, the mechanical transfer shows large (80% and more) voltage-controlled electro-mechanical amplification of the flow signal for frequencies below the sensor's resonance.
