Constructing a conductive composite that enables stretchable strain sensors to achieve high sensitivity while maintaining a wide sensing range is highly desired . In this report, we have successfully formulated a simple, biocompatible, and printable ink by mixing PDMS, PEDOT:PSS (referred to as PEDOT), and CB. Due to the immiscibility between PDMS and the solvent of PEDOT, the PEDOT-CB exhibits spontaneous phase segregation from the PDMS. Compared to the binary blends of PDMS/CB and PDMS/PEDOT, our PDMS/PEDOT-CB ternary blend offers significant advantages, including high sensitivity, a wide sensing range, and low hysteresis.
