DEFORMABLE ACTUATING DEVICE WITH COAXIAL CONFIGURATION

A deformable actuating device (1) with coaxial configuration is described, comprising: at least one structure (3) with concentric layers coaxial with respect to at least one longitudinal axis (A- A) composed of an at least partial alternated overlapping with at least two electro-active concentric layers (3a) coaxial with said longitudinal axis (A-A), and of at least three conductive concentric layers (3b) coaxial with said longitudinal axis (A-A); at least one controlling and managing system (5) adapted to supply each of such electro-active concentric layers (3a) with at least one different current/voltage value (V1, V2, V3, V4,..., Vn), said current/voltage values (V1, V2, V3, V4,..., Vn being mutually independent.
