Grips for testing of electrical characteristics of a specimen under a mechanical load
| DWPI Title: Device for electromechanically testing e.g. resistance of flexible conductive material for thin conductive films, has electrical measuring device for measuring electrical characteristic based upon electrodes being in contact with specimen |
| Abstract: Various technologies to facilitate coupled electrical and mechanical measurement of conductive materials are disclosed herein. A gripping device simultaneously holds a specimen in place and causes contact to be made between the specimen and a plurality of electrodes connected to an electrical measuring device. An electrical characteristic of the specimen is then measured while a mechanical load is applied to the specimen, and a relationship between the mechanical load and changes in the electrical characteristic can be identified. |
| Use: Device for electromechanically testing electrical properties e.g. resistance, capacitance, inductance and electrical impedance, of a specimen i.e. flexible conductive material (all claimed), used in exterior of an aircraft component. |
| Advantage: The device uses a protrusion to mate with a T-shaped slot on a grip mounting bracket so as to allow the gripping mechanism to be held securely in a place at the grip mounting bracket without requiring use of fasteners. The device provides the T-shaped slots and the protrusions to allow the gripping mechanisms to be removed from the grip mounting brackets, while maintaining a fixed relative position of the gripping mechanisms. |
| Novelty: The device has first and second gripping mechanisms (102, 104) being movable with respect to one another. A mechanical loading mechanism is coupled to the first gripping mechanism, and applies a mechanical load to a specimen (105). An electrical measuring device is coupled to first and second electrodes (206-212), and measures electrical characteristic of the specimen, while the mechanical load is applied to the gripping mechanism. The electrical measuring device measures the electrical characteristic based upon the first and second electrodes being in contact with the specimen. |
