Fingernail sensors unobtrusively measure the state of the human fingertip. The sensors optically measure the pattern of blood volume in the capillaries beneath the fingernail, which depends predictably on the posture of the finger as well as the forces of the fingertip pressing against a surface (including two dimensions of shear force).

Digital Clay combines the intuitive sculpting of natural clay with intelligent, programmable haptic feedback to the sculptor. The photograph shows two implementation concepts: the "formable crust" and the "bed of nails." The formable crust uses a new implementation of the ball joint (foreground) that, when combined as illustrated (on the middle left), enables the shell to conform to arbitrary shapes. As implemented in stereolithography (upper left), it can be scaled to fine resolution. The bed of nails concept and its control is studied using an expandible 5x1 array of cells (upper right). With MEMS technology under development for valves and actuators, this concept will be scalable to higher resolution, similar to the surrogate bed of nails model of a camera (middle right). This stereolithography model was created for user studies of the needed resolution and optimal surface.
