Abstract
A device is provided through which a set of information concerning tactile interaction between a manipulator and an object to be recognized is provided to the user. Several configurations are described, based on the piezo- and pyro-electric (ferroelectric) properties of polymeric materials, such as the polymer polyvinylidene fluoride (PVF.sub.2 or PVDF), different polypeptides and copolymers of PVF.sub.2 and TrFE. By arraying in a proper way various sensing layers, each featured by different sensory capabilities, a laminated sensor structure is obtained, able to provide a set of tactile information. The multilayered structure of the proposed device is inspired to that of the human skin, which includes superficial (epidermal) and deep (dermal) sensors.
