3D-printed soft electronics

Hydrogel-based electronic devices can be fabricated using a stretchable silver–hydrogel ink and an embedded 3D-printing technology. The photograph on the cover shows a 3D-printed conductive structure embedded in a soft hydrogel matrix.

  • Using common solid-state electrolyte films, multimode transistors can be created that exhibit different characteristics—tunable synaptic weights, high apparent mobilities, sharp subthreshold swings and memristive conductances—on demand and could be used create neural networks that function in different modes as needed.
