All-soft organic electrochemical diodes based on asymmetric active layers for signal isolation in deformable electronics.

All-soft organic electrochemical diodes with a rectification ratio of up to 2.23 × 10^4 operate stably under 30% tensile strain in deformable electronics.

• Why it matters: Developing mechanically compliant diodes is crucial for advancing deformable and human-centric electronic systems, but current materials and architectures face significant limitations in stability and compatibility.
• What they did: Researchers created the first all-soft organic electrochemical diode using an asymmetric active-layer geometry and an ultrathin ion-gel interface, achieving high rectification and mechanical stability.
• The result: This diode platform enables deformable rectifiers and logic gates, functions as a signal-isolation element in pressure sensors, and supports the development of fully integrated, human-centric electronic systems.
