Nowadays, the traditional face-to-face diagnosis mode between patients and doctors has not been able to meet people's growing demand for health care, and the traditional diagnosis mode needs to be further improved in the utilization efficiency of time and resources, which all give a huge challenge to the health care industry. Compared with traditional electronic devices and systems, flexible electronic devices have the characteristics of ultra-thin, low modulus of elasticity, light weight and good tensile properties. They have wide application prospects in consumer electronics, biomedicine and many other fields. Especially as a flexible electronic device for medical health detection and monitoring, it has become an important academic research frontier to measure various signal changes in human activities. This talk will first introduce the important breakthrough of flexible electronic technology in recent years, then introduce the progress of Prof. Ren’s group in graphene flexible electronic research. Finally, the prospect of wearable flexible electronic technology will be given.
