Abstract

The invention discloses a conductive hydrogel electrode material and application thereof. The conductive hydrogel electrode material is prepared from raw materials including acrylamide, sodium carboxymethyl cellulose, soluble metal inorganic salt, a diene-containing flexible long-chain compound, an initiator and water through full mixing, vacuum degassing and curing. The semi-interpenetrating or interpenetrating double-network hydrogel is formed by combining two specific polymers, and the inorganic salt or the conductive polymer is added for compounding, so that the prepared conductive hydrogel material has good mechanical property and a higher strain window, and still has good sensitivity under micro-deformation, and the signal reliability is enhanced.

Description

Technical field [0001] The present invention pertains to organisms or soft wearable robot technical field sensing apparatus, particularly relates to an electrically conductive electrode material and hydrogel applications. Background technique [0002] With the continuous development of productive forces and social progress of science and technology, businesses began to demand for virtual reality (VR technology) is increasing, VR technology has immersive, interactive features, and in order to achieve human-machine interactive effect, We need to make wearable electronics spend more sensitive and more wearable sensor attached to the skin. But not satisfactory is now widely used in various circuits in a conductor (e.g., metal, carbon-based materials, conductive composites, conductive polymer) poor stretchability, portable wearable not ideal. Thus, as the development of human skin can be as large tensile and compression deformation of the flexible and have the ability to perceive biom...
