Problems solved by technology

As far as the electrochemically driven devices in the liquid environment are concerned, they are currently very simple and complex. The current electrochemical devices place the entire test device in a liquid electrolyte environment. The liquid electrolyte environment contains acids, alkalis, and organic substances, which may cause Corrosion of the load or contact with organic and toxic substances is harmful to the human body; data collection is done by using a high-speed camera. This method not only has a large amount of data, but also takes a long time and has a large error. Changes in real-time output, so electrochemically driven devices need to be improved

The electrochemicalsystem comprises a signal applying device, a working electrode, a counter electrode, a reference electrode and an electrolyte, and the working electrode is an artificial muscle fiber to be tested. Thetest system comprises a load and a data acquisition device, the load is arranged outside the electrolyte, the load is connected with the working electrode and can be driven by the working electrode to move, and the data acquisition device is used for outputting and storing displacement change information of the load in the form of a voltage signal. The driving test device provided by the invention monitors the displacement change information of the load through a non-contact displacement sensor so as to realize the collection of the driving signal of the working electrode, and the load is externally arranged, so that the risk that the load is corroded by the electrolyte is avoided, and the driving test device is safer.

Description

technical field [0001] The invention relates to an electrochemical driving test device, in particular to a driving test device and a driving test method for electrochemical driving, which belong to the technical field of electrochemical performance testing. Background technique [0002] Artificial Muscle Fiber (Artificial Muscle Fiber) is a new type of intelligent driving material developed in recent years. It can produce reversible stretching, rotation, bending and other forms of motion under external stimuli. There are important application prospects. The driving methods of artificial muscles can be divided into three categories: electrothermal driving, solvent / gas adsorption and desorption driving, and electrochemical driving. Electrothermal drive is due to the expansion of the volume of muscle fibers due to the Joule heat generated by the current, thus forming a reversible torsion and stretching drive, but the slow temperature change limits the frequency, and is affecte...
