In situ mapping of mixed ionic–electronic channel swelling

2026-09-18

Operando monitoring of swelling in the channels of organic electrochemical transistors (OECTs) is essential for developing next-generation bioelectronics. Now, the spatial mapping of channel swelling with submicrometre resolution is demonstrated with a customized laser Doppler vibrometry platform. Channel structural defects are revealed, enabling engineering strategies for stable, high-fidelity OECTs and artificial neurons.
