MIT News  June 15, 2023 Conducting polymer hydrogels have emerged as a promising candidate for bioelectronic interfacing with biological systems. Despite the recent advances, the development of hydrogels with both excellent electrical and mechanical properties in physiological environments is still challenging. An international team of researchers led by MIT has developed a bi-continuous conducting polymer hydrogel that simultaneously achieves high electrical conductivity, stretchability, and fracture toughness in physiological environments. It is readily applicable to advanced fabrication methods including 3D printing. Enabled by these properties, they demonstrated multi-material 3D printing of monolithic all-hydrogel bioelectronic interfaces for long-term electrophysiological recording and stimulation […]
