Flexible electronics technology breaks the rigid physical form of conventional solid devices and systems, making it the most important route for the integration of human, machine and cyber. In order to moving flexible electronics technology forward, we have consecutively organized International Conference on Flexible Electronics three times. Last year ICFE 2021 was watched by more than 200,000 audiences via on-line platforms. Distinguished scholars including Prof. John A. Rogers, Prof. Yonggang Huang, Prof. Oliver G. Schmidt and Prof. Paul Burn have delivered splendid lectures in ICFE for at least once.

The fourth ICFE will be held this year from December 10 to 11, online. There will be one plenary session and several parallel sessions, in a way to forge interactions in all aspects and at various levels. We are honored to have three distinguished scholars, Prof. John A. Rogers from Northwestern University, Prof. Zhenan Bao from Stanford University and Prof. Takao Someya from Tokyo University, to give us plenary lectures on the frontier of flexible electronics. We will invite more lectures from scholars both in China and around the world soon.
