All‐Hydrogel‐Based Organic Electrochemical Transistors for Implantable Physiological Signal Monitoring

open access: yesAdvanced Science, EarlyView.
All‐hydrogel based n‐type depletion‐mode OECTs is developed using a semiconductor hydrogel formed via ionic‐liquid‐mediated phase separation, combining efficient ion‐electron transport, tissue‐like softness, and long‐term biocompatibility. The device can monitor EOG and ECG on human skin and record real‐time ECG subcutaneously in rats, providing a ...

High‐Performance Ambipolar Organic Electrochemical Transistors Based on Diketopyrrolopyrrole‐Dialkoxybithiazole Conjugated Polymers for Single‐component Inverters

open access: yesAdvanced Science, EarlyView.
Two donor‐acceptor conjugated polymers, incorporating diketopyrrolopyrrole (DPP) and dialkoxybithiazole (2Tz) units with ethylene glycol (EG) side chains, exhibit relatively balanced ambipolar organic electrochemical transistor (OECT) performance. This ambipolarity enables the realization of single‐component complementary inverters capable of ternary ...
