A new approach for the 3D printing of hydrogel-based electronics

 https://techxplore.com/news/2023-01-approach-3d-hydrogel-based-electronics.html

"printing conductive hydrogel ink into hydrogel supporting matrix, curing the two parts to form soft and stretchable device... orthogonal curing mechanism of alginate and polyacrylamide, main components of the hydrogel... combining conductive filler of silver flakes with granular gel particles to form segregated structure in conductive 3D printing ink... electrical conductivity of 1,400 S/cmcreated... hydrogel-based strain sensors, inductors and biological electrodes that performed exceptionally well"
