Research Progress in Functional Stretchable Organic Electronic Devices

Stretchable organic electronic devices are characterized with high mechanical stability, superior electronic stability, low cost, satisfactory biocompatibility, etc., thus having been regarded as an inevitable trend in the development of future electronics. Furthermore, the functional stretchable organic electronic devices provide pathways toward the emerging high-tech fields such as wearable and implantable devices, intelligent medical diagnosis system, software robots, etc. This review focuses on the research advances in functional stretchable organic electronic devices, including stretchable organic transistors (field-effect transistors, phototransistors, memory transistors and sensors), stretchable organic optoelectronic devices (light-emitting diodes, alternating current electroluminescent devices and light-emitting electrochemical cells), stretchable organic energy storage and conversion devices (solar cells, supercapacitors and nanogenerators), stretchable organic sensors (pressure sensors, strain sensors, tactile sensors, temperature sensors, gas sensors and other sensors), stretchable organic memory (resistive memory, magnetic memory and bionic synaptic memory) and other functional stretchable organic electronic devices. Finally, through the analyses of the existing scientific problems and future development of the functional stretchable organic electronic devices, we put forward some suggestions.
