Abstract : Summary: Proof-of-concept of Artificial Hair Sensor with CNT mechano-resistive elements demonstrated. CNT arrays examined that initially appear mechanically different by length, but DIC reveal a common failure criteria. Observed carbon hair deflection in-phase with gust-like disturbances without vibration - mapped the flow regime steady/unsteady. Computed frequency response plots for carbon hair structure in quasi-steady regime 2nd order like response. Found that elasticity and drag dominated the force balance in the carbon hair structure. Established criteria based on dimensionless groups to control hair dynamic response through selection of material and geometric properties.
