Jing Zhao is a member of Beijing Advanced Innovation Center for Intelligent Robots and Systems, Beijing Institute of Technology. He received the Ph. D degree in Condensed Matter Physics in 2016 from Institute of Physics, Chinese Academy of Sciences. After that, she worked as an Assistant Professor in Beijing Institute of Nanoenergy and Nanosystems (Chinese Academy of Sciences). From 2019, she joined School of Mechatronical Engineering, Beijing Institute of Technology. Her primary research interests focus on flexible electronics, especially devices based on two-dimensional materials for sensors, memory and so on. The main research interests of her group include artificial electronic skin, micro-nano robot fabrication, aim to develop advanced systems for human health monitoring and human-machine interface. Jing Zhao has published more than 30 papers on international journals including Nature Electronics, Advanced Materials, Advanced Functional Materials, JACS, ACS Nano and received more than 1200 citation.
Artificial electronic skin (e-skin), a network of mechanically flexible sensors which can wrap irregular surfaces conformally and quantify various stimuli sensitively, is potentially useful in healthcare monitoring and human-machine interaction (HMI). Although various approaches have mimicked the structures and functions of the human skin, challenges remain with high-density integration, super sensitivity, and multi-functionality. A multimodal and comfortable skin-inspired active-matrix circuitry is reported here with high pixel density based on all 2D materials, which can detect both mechanical interactions and humidity variations. The ultra-high sensitivity, long-term stability, and rapid response time for every pixel can fulfill simultaneous multi-stimulus sensing. Accordingly, a respiratory monitor is constructed to realize healthcare monitoring through observing the human breath frequency, intensity, and humidity in real-time. Moreover, the multimodal e-skin breaks through shackles of the contact sensor medium for HMI. 3D strain and humidity spatial mapping can reflect object location information even without contact, avoiding cross-infection of viruses effectively between users during the COVID-19 pandemic.
