Valves activated by electrically active polymers or by shape-memory materials, device containing same and method for using same

摘要

This invention concerns a valve (2), with at least one channel (3) running through it, allowing a fluid (F3) to be directed by transfer means within a device (1), the device (1) featuring at least one face (4), possibly flat, the valve (2) consisting of a film (7 or 16), flexible and/or which can be deformed, fixed on all or part of the face (4) of said device (1), and a film actuator (7), which enables said valve (2) to be activated or deactivated, this actuator consisting of an electrical power source. ;It also consists of a test sample card (1) equipped with at least one valve (2), and a process for actuating the valve (2), as described above. ;The invention is particularly applicable in the field of diagnosis.
