Stretchable conductors (SCs) have received increasing attentions due to their potential in flexible and stretchable electronics. High-performance SCs are capable of affording large tensile strains while maintaining high electrical conductivity. Herein, we report a stretchable film with a sandwiched structure of polydimethylsiloxane (PDMS)/highly conductive poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS)/PDMS. The sandwiched strain sensors based on PEDOT:PSS maintained high conductivity of 650 S cm–1 with 87% transparency at λ = 550 nm and showed a large strain-sensing region up to 30% strain and high sensitivity of 25–40. The work provides a new route to fabricating a highly stretchable, transparent and sensitive gum strain sensor.
