Title (EN) SOFT ACTUATORS AND ARTIFICIAL MUSCLES
(FR) ACTIONNNEURS MOUS ET MUSCLES ARTICIFIELS
Abstract:
(EN) A chemical (coating and reduction)/mechanical/electrical treatment of ion-exchange materials (preferably ion-exchange membranes) to convert them to artificial muscles. The figure is a perspective view of an actuator of the invention showing the treated membrane actuator (A) with electrodes (25 and 26) placed at one end of the membrane, the electrodes being further attached to a power source (35). Artificial muscles created by the inventive method are capable of undergoing electrically-controllable large deformations resembling the behavior of biological muscles. A typical flap muscle of 0.2 - 0.4 mm thickness, 2 - 5 mm width and 20 mm length manufactured by the inventive process can achieve a completely reversible maximum deflection of 12 - 15 mm under a maximum voltage of 2.0 - 2.5 volts.
(FR) Traitement chimique (enduction/réduction)/mécanique/électrique de matériaux échangeurs d'ions (de préférence de membranes échangeuses d'ions) permettant de transformer ces derniers en muscles artificiels. La figure 1 représente une vue en perspective d'un actionneur, soit un actionneur à membrane traitée (A) doté d'électrodes (25, 26) placées à une extrémité de la membrane, les électrodes étant ensuite fixées à une alimentation (35). Les muscles artificiels créés selon le procédé de l'invention sont capables de résister à des déformations importantes induites électriquement, qui ressemblent au comportement de muscles biologiques. Un muscle à volet classique d'une épaisseur de 0,2 à 0,4 mm, d'une largeur de 2 à 5 mm et d'une longueur de 20 mm, fabriqué selon le procédé de l'invention peut être défléchi d'au maximum 12 à 15 mm sous une tension maximum de 2,0 à 2,5 volts.
