Claims
- 1. A sensing device comprising:
an ion exchange, lithium-treated membrane; and a metallic coating on said membrane forming at least one electrode wherein bending of said membrane generates electrical potential between said at least one electrode and another point.
- 2. A sensing device comprising:
an ion exchange membrane having a length defining a relative path wherein said membrane comprises at least two parts fixed to positions along said path; and a metallic coating on said membrane forming at least one electrode wherein bending of said membrane displaces at least one part of said membrane, at a position between said at least two fixed positions, thereby generating an electrical potential between said at least one electrode and another point.
- 3. A sensing device comprising:
an ion exchange membrane having a length defining a relative path wherein said membrane comprises at least one part fixed to a position along said path; and a metallic coating on said membrane forming at least one electrode wherein bending of said membrane to displace at least one part of said membrane from said path by at least 1% of said length generates an electrical potential between said at least one electrode and another point.
- 4. A sensing device comprising:
an ion exchange membrane having a length defining a relative path wherein said membrane comprises at least one part fixed to a position along said path; and a metallic coating on said membrane forming at least one electrode wherein bending of said membrane to displace at least one part of said membrane from said path by at least 0.1 mm generates an electrical potential between said at least one electrode and another point.
- 5. A sensing device comprising:
an ion exchange membrane having a material property selected from the group consisting of mechanical, rheological, chemical, thermal, magnetic, and electrical; and a metallic coating on said membrane wherein said metallic coating forms at least one electrode wherein application of an electrical potential between said at least one electrode and another point alters said material property.
- 6. A sensing device comprising:
an ion exchange membrane; and a metallic coating on said membrane wherein said metallic coating forms at least one electrode wherein displacement of said membrane generates a measurable signal useable in a feedback control system.
- 7. The device according to claim 6, wherein said feedback control signal feeds back to said sensor device.
- 8. The device according to claim 6, wherein said control signal feeds back to said sensor device to maintain said sensor in a predetermined position.
- 9. A sensing and actuating device comprising:
an ion exchange membrane; and a metallic coating on said membrane forming at least one electrode.
- 10. The sensing and actuating device according to claim 9, wherein said device comprises a feedback control system.
- 11. A sensing device comprising:
an ion exchange membrane; a metallic coating on said membrane forming at least one electrode; and a surrounding coating forming an outer surface of said sensor device.
- 12. The device according to claim 11, wherein said surrounding coating encapsulates said membrane device.
- 13. The device according to claim 11, wherein said surrounding coating provides biocompatibility with biological material in which said sensing device is placed.
- 14. The device according to claim 11, wherein said surrounding coating protects a pharmacological material.
- 15. The device according to claim 11, wherein said surrounding coating permits transport of at least one member selected from the group consisting of mass transport and energy transport.
- 16. The device according to claim 11, wherein said surrounding coating comprises a non-porous material.
- 17. A actuating device comprising:
an ion exchange membrane; a metallic coating on said membrane forming at least one electrode; and a surrounding coating forming an outer surface of said actuator device.
- 18. The device according to claim 17, wherein said surrounding coating encapsulates said membrane device.
- 19. The device according to claim 17, wherein said surrounding coating permits transport of at least one member selected from the group consisting of mass transport and energy transport.
- 20. The device according to claim 17, wherein said surrounding coating comprises a non-porous material.
