Tactile coding of object curvature by slowly adapting mechanoreceptors

Through the used of mechanistic models of the primate fingertip, the relationship between the biomechanics of primate fingertip and the responses of slowly adapting mechanoreceptors (SAs) involved in the sensing of object curvature had been investigated two plane strain models of circular cross-section were chosen for analysis. The first model consisted of a linear elastic and isotropic solid enclosing a central rigid bone of 2 mm diameter; the second model consisted of a 1 mm thick layer of the same solid enclosing an incompressible fluid.
