Overview
- A peer-reviewed study in Angewandte Chemie describes water‑soluble monomers that polymerize in water under visible light without toxic additives or UV.
- Electrodes are formed in place by spreading the monomer solution, illuminating selected areas, then rinsing away unreacted material.
- The team patterned electrodes on glass, textiles, and the skin of anesthetized mice, achieving clearer low‑frequency brain recordings than conventional metal EEGs.
- The resulting organic mixed conductors carry ions and electrons and were produced using simple light sources, including basic LED lamps.
- Researchers foresee uses in wearable sensors and large‑scale organic electronics made without dangerous solvents, with longer‑term validation still required.
