Despite the likely first impressions created by the title, this paper does not hold the cure to balding. It does, however, describe a remarkable kind of sensor that measures fluid flow. Since "insects and fish use clusters of hair cells to monitor air or water flow," researchers at the University of Illinois at Urbana-Champaign developed an artificial haircell that behaves in a similar way. The paper introduces the manufacturing processes used to create the sensor and shows experimental results for a few configurations. The authors indicate that the flexibility of fabrication materials allows the artificial haircell sensor to be made on a layer of polymer skin.
