High-resolution hair shaft deflection measurements for a hair shortened to 114.5 μm. (a) High-resolution load–deflection curve; example of the load curves used to determine the two- and three-parameter model constants. Average of five measurements (±s.d.) obtained at an angular velocity of 0.029±0.004 rad s−1. The dashed line represents the minimum angle of deflection necessary to elicit a nervous response as measured electrophysiologically (Barth & Höller 1999). (b) Enlarged initial region of the load–deflection curve displayed in (a).
