Title (EN) DEFORMABLE ACTUATING DEVICE WITH COAXIAL CONFIGURATION
(FR) DISPOSITIF D'ACTIONNEMENT DÉFORMABLE PRÉSENTANT UNE CONFIGURATION COAXIALE
Abstract:
(EN) 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.
(FR) L'invention a trait à un dispositif d'actionnement déformable (1) présentant une configuration coaxiale, et comprenant : au moins une structure (3) qui comporte des couches concentriques ayant au moins le même axe longitudinal (A-A) et composées d'un chevauchement qui alterne au moins partiellement possédant au moins deux couches concentriques électro-actives (3a) qui ont le même axe longitudinal (A-A) ainsi que d'au moins trois couches concentriques conductrices (3b) ayant le même axe longitudinal (A-A) ; au moins un système de commande et de gestion (5) conçu pour fournir à chacune de ces couches concentriques électro-actives (3a) au moins une valeur de courant/tension différente (V1, V2, V3, V4, ..., Vn), lesdites valeurs de courant/tension (V1, V2, V3, V4, ..., Vn) étant indépendantes les unes des autres.
