High current hydrogels: Biocompatible electromechanical energy sources

Innovations in soft materials bridge electronic conduction in conventional electronics and ionic conduction in biology. In a recent issue of Science, Dobashi et al. describe a hydrogel that generates large ionic currents in response to applied force. The technology could enable sensors and energy generators for wearable and implantable devices.
