Title:
ELECTROCHEMICAL ARTIFICIAL MUSCLE SYSTEM AND ELECTROCHEMICAL ARTIFICIAL MUSCLE TESTING DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/173839
Kind Code:
A1
Abstract:
An electrochemical artificial muscle system and an electrochemical artificial muscle testing device. The electrochemical artificial muscle system comprises a working electrode including conductive fibers having a spiral structure; a counter electrode containing selected metal elements; and an electrolyte comprising an ionic liquid containing selected ions, the selected ions comprising the selected metal elements. The working electrode and the counter electrode are both in contact with the electrolyte. An artificial muscle system based on an aluminum ion battery system exhibits a contraction retention characteristic, that is, artificial muscle fibers contract when a voltage is applied, and after the voltage is removed, the contraction state of the artificial muscle fibers can still be maintained almost without attenuation within 450 s. At the same time, the artificial muscle fiber has good energy storage performance, and the capacity is 20-100 mAh g-1, so that the energy injected into the artificial muscle in a driving process is stored, and large energy loss is avoided.
