Here, we propose fully soft OECTs with all soft components, including PEDOT:PSS-based soft channel, which shows substantial mechanical/electrical properties. In addition, further demonstrated skin-mountable amplifier implies the strong potential of...

Wearable electronics, particularly soft strain sensors with direct skin adhesion, play a crucial role in applications such as smart healthcare systems and human-machine interfaces. However, existing approaches for developing dry-adhesive...

With growing interest and effort in developing organic electronics for future technologies such as wearable electronics, organic e-wastes generated during synthesis and disposal are becoming an inevitable environmental issue. Organic e-wastes possess unforeseeable potential genotoxicity and cytotoxicity in nature and humans, but efforts to reduce e-wastes have primarily focused on recapturing metallic materials. Here, we report a recyclable organic flexible (ROF) electronic device enabled by closed-loop recycling of entire materials recapturing and reusing through selective dissolution and spin-coating-free fabrication. The ROF electrode and electronics show reliable electrical properties under mechanical bending and after five times recycling. Moreover, ROF transistors and logic gates based on organic semiconductors and dielectrics were fabricated, and recycled devices show no considerable degradation. Finally, we achieved the sustainable devices cycle by reconstructing various ROF electronics using only recycled materials from different functional devices. The ROF electronics in this work provide a promising strategy for a sustainable future wearable electronic system.
