. The proposed flexible OFET fabricated using microelectronic inkjet printing exhibits stable output performance under certain bending and temperature conditions. In addition, it is the first time to combine the flexible OFET with an origami-inspired electricity generator to realize the circuit on and off, which provides a new idea for the application of self-powered transistors and the development of flexible electronics.
