    We fabricated stretchable molybdenum disulfide thin-film transistors (MoS2 TFTs) on poly(dimethylsiloxane) substrates using ion gels as elastic gate dielectrics. The TFTs exhibited an electron mobility of 1.40 cm2/(V·s) and an on/off current ratio of 104 with a notably low threshold voltage (∼1 V). Furthermore, our MoS2 TFTs operated at a mechanical strain of 5% without significant degradation of their electrical properties. These results demonstrate the potential for using MoS2 films for stretchable electronics.
