Solution-processed electronic materials have the potential to create a new manufacturing paradigm and applications domains beyond those now dominated by silicon technology. These materials can be deposited and patterned with tools commonly used in the graphics design and printing businesses. Over the past 10 years, solution-processed semiconducting materials have been studied largely for incremental application in information display. However, combining derivatives of these semiconductors with emerging solution-dispersible metal and metal oxide nanoparticles and nanowires enables the fabrication of electronic devices that are fully built from solution. This establishes a new device processing platform which, in turn, allows device form factors and integration of functionality in systems not feasible in any conventional semiconductor technology.

In this talk, I will discuss the development of a flexible integrated blast dosimeter to illustrate and demonstrate the challenges and advantages of using solution-processed electronic materials for flexible and disposable applications.

About the speaker:
Ana Claudia Arias is an Acting Associate Professor at the Electrical Engineering and Computer Science Department at the University of California in Berkeley. Prior to joining the University of California, she was the Manager of the Printed Electronic Devices Area and a Member of Research Staff at PARC, a Xerox Company, Palo Alto, CA. At PARC she used inkjet-printing techniques to fabricate organic active matrix display backplanes for paper-like displays and flexible sensors. She went to PARC from Plastic Logic in Cambridge, UK where she led the semiconductor group. She did her PhD on semiconducting polymer blends for photovoltaic devices at the University of Cambridge, UK. Prior to that, she received her master and bachelor degrees in Physics from the Federal University of Paraná in Curitiba, Brazil. Her research work in Brazil focused on the use of semiconducting polymers for light emitting diodes. Ana Claudia is a member of the board of directors of the Materials Research Society (MRS) and a member of the technical advisory board of ThinFilm Electronics and Linde Nanomaterials.
