Gel electrolyte-gated organic electrochemical transistors (OECTs) are promising bioelectronic devices known for their high transconductance, low operating voltage, and integration with biological systems. Despite extensive research on the performance of OECTs, a precise model defining dependence OECT gel electrolytes is still lacking. In this work, we refine device to comprehensively account electrical double layer (EDL)’s capacitance electrolyte. Both experimental data theoretical calculations indicate that maximum transconductance contingent upon ion concentration, drain scan rate, highlighting strong correlation between hydrogel Overall, serves as tool improving enabling further development devices.

Abstract Electronic skin (E-skin), a conformal human-machine interface, holds promise for healthcare monitoring and personal electronics. However, traditional fabrication methods face challenges of reliance on non-sustainable materials, intricate time-consuming processes, material softness-induced fragile transfer to target substrates. Inspired by "milk skin" phenomenon, we developed rapid "dipping-dipping" molecular assembly method in-situ fabricate cellulose-based bio-skin within seconds, exhibiting ultra-thin, high conformal, shape-customizable, degradable, low impedance performances. This technique immerses substrates sequentially into carboxymethyl cellulose (CMC) Cu(II) solutions, leveraging strong metal-coordination interactions. Membrane formation efficiency, influenced the oxidation metal ions, follows order: > Fe(II) Ca(II). CMC-Ag(I)/CMC-Cu(II) form stable membranes, whereas CMC-Fe(II) is fragmented structures, CMC-Mg(II)/CMC-Ca(II) remain in solution. adaptable extends other biomacromolecules like methylcellulose chitosan, broadening applications. The enables real-time electrocardiograms (ECG), electrooculograms (EOG), electroencephalograms (EEG), electromyograms (EMG), showcasing its potential wearable, biocompatible electronics healthcare.
