E-MRS Spring 2012 - Symposium Q
Novel materials and fabrication methods for new emerging devices
This symposium aims at bringing together scientists to discuss the different issues related to the application of new nano and bio materials into opto/electronic, sensing and microsystems devices. The objective is to cover the major aspects from the materials synthesis, their functionalization, the fabrication techniques for their integration, to the devices themselves.
The next generation of opto/electronics devices, sensors, micro and nanosystems is going towards a higher level of miniaturization and lower power consumption for their integration in new emerging systems such as wireless systems. New strategies are required in the developments of these components for their deployment, in autonomous systems, building automation, consumables goods, wireless sensor networks (WSN), ambient assisted living (AAL), body sensor network (BSN), smart labels (e.g. RFID), the internet of things (IoT)...
Nanotechology combined with printed electronics in its large definition have been identified as key enabling technologies for the deployment of such systems. The developments of these technologies hold the potential to revolutionize the smart systems of tomorrow. Successful developments could lead to a wide range of novel devices and technologies useful and essential for the next generation of ultra-low power sensors and microsystems, highly sensitive sensors, wearable/flexible/transparent/stretchable/ devices, smart textile, etc.
A significant increase in the activities on these topics has occurred recently and new communities of researchers are emerging and have started to interact more closely. This symposium aims at discussing the most recent and relevant developments and results pertaining to the synthesis, processing, characterization and modelling of materials and their functionalization and integration as active elements in opto/electronics, sensors and micro and nanosystems based devices. Leading experts from the fields of nanomaterials, printed electronics, sensors, micro and nanosystems will get together to discuss the state of the art and to define future research directions.
Since the reporting of the first organic transistor and integrated circuits, an astonishing number of university groups and non-corporate research centers have engaged in organic and printed electronics research and have made critical contributions in many important areas such as device physics, materials chemistry, process optimization, and novel applications. The growing number of industries involved stands as a testament both to the progress made in developping the technology in corporate environments as well as to the continued commercial interest. The main driving applications for organic/printed flexible electronics are currently the display, lightning, solar cell and electronics (RFID) industry, and a significant expansion of the domain to the fields of sensors, transparent/stretchable electronics and smart textiles is expected. The complete technology chain is being established with actors in the field of materials, processing and characterization equipment, and production. Benefits of printing devices on foil include their potentiallity to be light weight, foldable/rollable, transparent, thin and conformal, wearable, and produced at large scale and low-cost based on additives processes with a reduced infrastructure, leading the way towards greener manufacturing processes. However, a lot of materials, for instance on the ink formulation, and processing issues remained to be sorted out for emergence of new types of devices and their large scale manufacturing in a reproducible way.
In order to reach these goals a lot of effort has been put in the materials preparation and integration techniques. In particular, progress has been made on the synthesis as well as on the structural, physical and chemical characterization of nano-materials with sizes in the range of 1-100nm that exhibit size dependent properties. Specifically, the field of nanostructured morphologies (in particular nanowires and nanorods) has become one of the most active research areas within the nano-science community. A huge number of papers has been published on nanowires over the past decades, which has increased exponentially, with most of the activity and development happening in the last ten years. The emergence of nanowires as building blocks of multi-functional devices has already brought fundamental changes to the future of the IC industry and will possibly allow for a continuing compliance with Moore’s Law. Nanowires can have very promising applications, primarily in logic circuits, but also as sensing and active elements for the development of highly sensitive bio/chemical/photon sensors. Nano-materials and nanostructures are also of high interest for the development of printed devices. It is a critical step to afford reliable and economic scaled-up processes that integrate nanowires into electronic and printed devices.
