A sensing device and a system using the same for detecting and analyzing grasping forces in a dynamic manner includes a number of finger pads for measuring fingertip forces and motions. Each finger pad is mounted at one end of a corresponding one of a plurality of arms. The arms are articulated to one another by being joined at their opposite ends through one or more joints that allow motion of the arms relative to each other in one or more directions. The device generates time varying signals which can be used to investigate the temporal relationships and coordination among finger actions. In addition, a mechanism is preferably provided for imposing mechanical actions and/or perturbations to the device or fingers which generate a measurable response by the fingers. The device can alternatively be employed as a computer input device in which manipulation of the various finger pads can generate signals that represent particular inputs or commands.
