Stretchable Redox-Active Semiconducting Polymers for High-Performance Organic Electrochemical Transistors

Yahao Dai et al.

Summary: Organic electrochemical transistors (OECTs) have high amplification and sensitivity to biological signals, making them a promising platform for next-generation bioelectronics. However, achieving seamless tissue-electronics interfaces with softness and stretchability has been a challenge due to the lack of stretchable redox-active semiconducting polymers. This study reports a stretchable semiconductor for OECT devices, which exhibits exceptional stretchability and high OECT performance. The polymer's design features, including a nonlinear backbone architecture, moderate side-chain density, and high molecular weight, enable the combination of stretchability and OECT performance. The highly stretchable polymer semiconductor allows for fabricating intrinsically stretchable OECTs with high transconductance and biaxial stretchability, and demonstrates on-skin electrocardiogram recording with built-in amplification and unprecedented skin conformability.

High-Gain Chemically Gated Organic Electrochemical Transistor

Siew Ting Melissa Tan et al.

Summary: Organic electrochemical transistors (OECTs) have shown promising performance as transducers and amplifiers of low potentials due to their exceptional transconductance enabled by the volumetric charging of organic mixed ionic/electronic conductors (OMIECs). However, current approaches that directly conduct chemical reactions within the OECT electrolyte do not fully leverage the OECT's large transconductance, resulting in sub-unity transduction of gate to drain current. This study presents an alternative device architecture that separates chemical transduction and amplification processes to achieve high-gain chemical OECT transducers.
