Title (EN) ELECTROCHEMICAL ACTUATOR
(FR) ACTIVATEUR ÉLECTROCHIMIQUE
Abstract: front page image
(EN)The present invention provides systems, devices, and related methods, involving electrochemical actuation. In some cases, application of a voltage or current to a system or device of the invention may generate a volumetric or dimensional change, which may produce mechanical work. For example, at least a portion of the system may be constructed and arranged to be displaced from a first orientation to a second orientation. Systems such as these may be useful in various applications, including pumps (e.g., infusion pumps) and drug delivery devices, for example.
(FR)La présente invention concerne des systèmes, dispositifs et procédés associés impliquant une activation électrochimique. Dans certains cas, l'application d'une tension ou d'un courant à un système ou dispositif selon l'invention peut générer une modification volumétrique ou dimensionnelle qui peut produire un travail mécanique. Par exemple, au moins une portion du système peut être construite et disposée pour se décaler d'une première orientation vers une seconde orientation. De tels systèmes peuvent être utiles dans diverses applications, comme les pompes (par ex. pompes à perfusion) et les dispositifs de distribution de médicaments, par exemple.
