Adding electrical conductivity to a self-healing organogel opens up avenues for soft robotics and tissue engineering. NBThighlight
Self-healing hydrogels use spontaneous intermolecular forces to recover from physical damage caused by extreme strain, pressure or tearing. Such materials are of potential use in soft robotics and tissue engineering, but they have relatively low electrical conductivity, which limits their application in stretchable and mechanically robust circuits.
Here we report an organogel composite that is based on poly–sodium borate and has high electrical conductivity , low stiffness , high stretchability and spontaneous mechanical and electrical self-healing. The organogel matrix is embedded with silver microflakes and gallium-based liquid metal microdroplets, which form a percolating network, leading to high electrical conductivity in the material.
