Recent progress in stretchable organic field-effect transistors: key materials, fabrication and applications

“…The common method is to mix a semiconductor polymer with the elastic solution, and then coat the uniformly blended solution on the substrate and evaporate the solvent to form a stretchable semiconducting composite film. 73,74 Using this method, Shin et al 75 mixed P3HT solution (0.25 wt%) with SEBS solution of different concentrations (0-25 wt%) to prepare a P3HT/SEBS mixed solution, then cooled the mixed solution at À15 1C for 30 min, and spin coated onto the PDMS substrate at room temperature (25 1C). During spin coating, the P3HT nanofibers separated from SEBS solution and aggregated to form a network structure (Fig.…”

“…Electronic skin can not only mimic the characteristics of human skin (flexibility and extensibility), but also have similar perceptual functions. 73 Electronic skins have been used to conveniently monitor the body's small physiological changes in daily life, making it possible to continuously track the health status of the human body. Guan et al 114 made a smart electronic skin based on a sensing array and fully stretchable field-effect transistor tubes, which fits well with the back of a human hand and exhibits excellent mechanical deformation capabilities.…”

Healthcare Monitoring Sensors Based on Organic Transistors: Surface/Interface Strategy and Performance

“…Guo's research group used SEBS/CQD hybrid material as the flexible polymer dielectric layer for OFETs. [ 263 ] The stretching strain of the dielectric material reaches over 620%, and the dielectric constant is significantly improved. The high dielectric constant and excellent flexibility provide low voltage, high signal amplification capability, and potential for stretchable wearable devices.…”

Aligned Conjugated Polymer Nanofiber Networks in an Elastomer Matrix for High-Performance Printed Stretchable Electronics

“…Nevertheless, a high mobility of 2.08 cm 2 V –1 s –1 under 100% strain for the DCB:CF-processed film is comparable to the state-of-the-art stretchable polymer films (Table S4). ,,− ,,− The evolution of charge mobilities for different films under stretch-release cycles is further compared (Figure c, Figures S18 and S19, and Table S10). The DCB-, DCB:CF-, and CF-processed films achieved mobilities of 0.21, 1.66, and 0.55 cm 2 V –1 s –1 under 500 stretch–release cycles at 50% strain, retaining ∼16%, 47%, and 56% of their initial mobilities.…”
