High Sensitivity Nanotube and Graphene-Enabled Sensor Technologies (IDTechEx Sensors USA 2015)

Carbon nanotube and graphene-based transistors and electrodes have demonstrated record sensitivity in vapor sensor applications due to their high specific surface area and confined electron transport properties. The use of nanotube or graphene ink offers the possibility to manufacture such sensors at low-cost and large scale. I will discuss the coating and surface treatment of the nano-carbon which is critical to impart specificity to the sensors. I will cover of state of the art examples of nanotube and graphene-enabled sensors, processing methods as well as relevant companies that work in this cutting-edge field.

Dr. Jens Kroeger is the CTO of Raymor and NanoIntegris. After his PhD in physics at McGill, he joined Raymor as an NSERC postdoctoral fellow in 2010. Under his leadership, Raymor implemented a large scale nanotube production technology. He developed the purification methods that led to electronic grade plasma nanotubes currently sold by NanoIntegris. He currently manages the nanotube production on Raymor's industrial unit and directs the R&D team in their efforts on new materials and applications.

Jens Kroeger is a member of the CSA Technical Committees developing the ISO standards for nanomaterials safety datasheets and safe nanomaterials production. Dr. Kroeger has published over 20 peer-reviewed scientific articles and technical reports.

NanoIntegris Technologies, a Raymor subsidiary, is a world leading provider of premium nano-carbon materials such as single-wall carbon nanotubes, graphene, and high mobility semiconductor inks. Our inks are formulated for inkjet and aerosol printers and used in the development of the next generation of high mobility transistors for sensing, logic and display driver applications. Using a patented plasma technology, Raymor Industries synthesizes single-wall carbon nanotubes at industrial scale and with superior quality for transparent conductive and ESD applications. Standing behind over 450 academic publications our materials were recognized with the Best Technical Development Materials Award at PE USA 2014.
