Flexible electronics are an exciting frontier for the next generation of wearable and portable devices. Flexible pressure sensor arrays, as part of artificial electronic skins (E-skins), have attracted increasing massive attention due to their unique advantages in potential applications of health monitoring. Monitoring body physiological signals including blood pressure, heart rate, and wrist pulse, presents one of the most convenient methods for non-intrusive diagnosis of diseases.
Here we present our recent works on the formation of free standing Single-walled Carbon Nanotubes (SWNTs) and Functionalized Graphene Oxide (FGO) ultrathin films, and the construction of transparent and flexible E-skins. With the high conductivity of SWNTs/FGO network and micro-patterned PDMS structures, we developed a facile and low-cost method for fabricating highly flexible pressure sensor arrays
Electronic skins are ultra-sensitive (detection limit <0.6 Pa) for detection of super-slight forces with short response time (<10 ms) and excellent stability (>50000 cycles). Furthermore we demonstrated their applications as the wearable devices in monitoring human physiological signals, which proves that the flexible E-skins are suitable for wearable real-time diagnosis of diseases and health assessment.
Speaker Biography (Ting Zhang)
Professor Ting Zhang is leading a research group at Suzhou Institute of Nanotech, Chinese Academy of Sciences. He received his Ph.D. degree in chemical engineering at University of California, Riverside in 2007. After that he worked as a research scientist at Nanomix Inc. to commercialize nanoelectronic sensor devices. Prof. Zhang's research focuses on combining high-throughput and manufacturable printing and MEMS techniques for the fabrication of electronic nanosensors and individually addressable nanosensor arrays. The nanosensors are mainly used for medical diagnostics and environmental monitoring applications.

The Printable Electronics Research Center (PERC) at the Suzhou Institute of Nano-tech and Nano-bionics (SINANO), Chinese Academy of Sciences, was established in 2010, which was at the time the first research center in China dedicated to printed electronics R&D. PERC now has more than 70 researchers and more than 2000 m2 lab spaces. PERC's mission is to develop technologies that would eventually become industrialized. In the past 9 years, PERC researchers have set up 4 spin-off companies. The hybrid printed metal mesh technology developed by PERC researchers has been transferred to touch panel industry and went into mass production.
