The Future Medical Revolution? Development of Bioelectronic Hydrogels to Monitor Internal Activities: Molding Like Wet Sand, Reading Nerves

The University of Washington has developed a conductive granular hydrogel composed of PEDOT:PSS microparticles. These particles can be easily shaped via injection or 3D printing and, once adhered, function as a porous network for acquiring and stimulating biological signals. As a demonstration, they recorded olfactory signals from a grasshopper's antenna. This soft electrode is a promising alternative to rigid metal electrodes, with potential applications in regenerative medicine and implantable devices. The university is also proceeding with patent applications and technology transfer. On social media, researchers and industry professionals have expressed high expectations for the implementation of flexible electrodes.
