Ionic conductivity and excitation frequency effects in iontronic pressure sensing

Caption

Using an ionic-droplet model sensor and electrochemical impedance spectroscopy-guided analysis, we demonstrate that lower ionic conductivity and higher excitation frequency amplify apparent capacitance variation. The resulting sensitivity enhancement highlights measurement parameters and ionic conductivity as powerful yet overlooked dimensions in iontronic sensor design.
