Artificial hair sensors consisting of a piezoresistive carbon‐nanotube‐coated glass fiber embedded in a microcapillary are assembled and characterized. Individual sensors resemble a hair plug that may be integrated in a wide range of host materials. The sensors demonstrate an air‐flow detection threshold of less than 1 m/s with a piezoresistive sensitivity of 1.3% per m/s air‐flow change.
