Inspired by the electric eel, researchers from the University of Fribourg in Switzerland have developed 3D-printed hydrogels that could generate up to 110 volts of electricity in an instant. The rows of gels contain positively and negatively charged ions that combine together to mimic the eel”s cellular structure. Unlike typical batteries, these systems are soft,
A hydrogel made from nanoflakes of synthetic clay and sugar chains extracted from seaweed could act as an injectable bandage to stop internal bleeding on a battlefield, in a surgical suite, or at an accident site. Commercially available absorbant gauzes or gels prompt blood clotting and quickly stop bleeding when applied with pressure on external
