Abstract |
we present a microstructured hydrogel sensing platform based on electrochemical reactions sensitive to specific external stimuli. The platform is composed of a hydrogel pyramidal array on a single electrode. Each pyramid serves as a spatially separated pixel for sensing stimuli without individual electrodes. Depending on the electrolyte for specific stimuli, our platform possesses a sensing ability with the high sensitivity of an electrochemical reaction for environmental change in addition to pressure via deformation of the viscoelastic hydrogel. This work represents a step toward the application of sensitive electrochemical reaction on electronic sensing platform for various external stimuli based on address-free and biocompatible hydrogels. |
