Abstract

The invention discloses a device for testing comprehensive mechanical and electrical properties of an ionic polymer-metal composite (IPMC). The device comprises a base frame and is characterized in that a lifting platform, a Y-directional movable platform and an X-directional movable platform are arranged on the base frame, wherein a demountable sample fixture is arranged on the X-directional movable platform, a resonance displacement input device, a displacement sensor and a micro-force sensor are arranged on the lifting platform, and a CCD (charge-coupled device) camera is arranged above the sample fixture; and a power amplifier (PA), a current / voltage test board and a computer system are also arranged on the base frame, wherein the PA, the current / voltage test board and a sample are electrically connected together to form an electrical property test circuit, the computer system acquires the measured data output by the displacement sensor, the micro-force sensor, the CCD camera and the current / voltage test board so as to generate an excitation signal, and then the PA performs measurement control on the sample.

Description

technical field [0001] The invention relates to an analysis and measurement control technology, in particular to a comprehensive electromechanical performance test device and test method for the output force, deformation displacement and corresponding response current of an ion polymer-metal composite (IPMC) material. Background technique [0002] The ionic polymer-metal composite (IPMC) material is an ionic electro-actuated polymer with light weight, good flexibility, rapid response and bidirectional reversible functions of sensing-actuation, which can be used to make electromechanical transducers such as drives Devices to replace traditional piezoelectric ceramics are new smart materials that have emerged in the past two decades and have great application potential. In recent years, a large number of experimental studies on the material properties of IPMC materials have focused on improving their electromechanical properties. In experiments, IPMC materials are usually made...
