Structure and recycling

PEDOT and PSS are interwoven with a cellulose network, and used films can be dissolved and re-cast into new films.

Characterization data

Hysteresis, cycling stability and body-motion sensing results.

Six AH-CEPT data panels. Top: R/R₀ hysteresis under strain, degree of hysteresis compared with reported stretchable conductors, and 1,000-cycle test. Bottom: real-time sensing signals for finger bending, wrist bending and breathing
