Recent progress in stretchable organic field-effect transistors

Stretchable organic field-effect transistors (STOFETs) employing organic semiconductors as active layers are highly attractive ongoing from health monitoring to biological research owing to some favorable advantages over their inorganic counterpart, including light weight, low cost, solution processing, high flexibility and simple adjustment of functionalities through molecular design. Although the development of STOFETs with original electrical performances under large mechanical deformation remain rudimentary, major efforts have recently been devoted to the investigation on STOFETs, and remarkable advances in stretchable components and novel fabrication methods have been achieved. A detailed overview of the advantages, challenges and current achievements in STOFETs was given including stretchable electrodes, semiconductors, dielectrics and substrates. Furthermore, conclusions and prospects for the future development of STOFETs with both high stretchability and superb electrical performances fabricated using intrinsically stretchable components are proposed.
