Polymer-based materials made of hazardous solvents and nonrecyclable resources used to create strain-sensing devices are unsuitable to meet sustainability standards for easy disposability. Scientists at the University of Sussex have now developed fully biodegradable and highly effective health sensors using seaweed, that can be applied like a second skin . Researchers added a critical amount of graphene to the seaweed, a known insulator, to create an electrically conductive film.
This film, when soaked in a salt bath, quickly absorbs water. This results in the formation of soft, spongy, and electrically conductive hydrogel that could measure an object just 2 mg in mass, impacting its surface. The formulation of sustainable graphene algae hydrogel has the potential to revolutionize health monitoring technology, significantly improving the patient experience without using invasive…
