Development of mechanical reliability testing techniques with application to thin films and piezo MEMS components

This work focuses on the development of a method for probing the mechani- cal response of thin film materials based on miniature tensile testing. A number of mechanisms that may compromise the performance and potentially limit the operational lifetime of MEMS devices which incorporate functional ferroelectric ceramics were also identified and investigated. Reliability of piezo MEMS com- ponents was studied at a wafer and at a device level through the development of appropriate techniques based on miniature tensile testing, time- resolved mi- cro RAMAN spectroscopy and laser Doppler vibrometry. Micro tensile testing was further used for the extraction of the elastic properties of various thin film materials. A miniature tensile stage was developed in common with DEBEN UK for the mechanical characterization of functional thin film materials like PZT and ZnO ceramics, which are commonly used in MEMS fabrication. The stage is of- fered with a piezo electric motor which can be fitted with interchangeable heads. These can be combined with di.erent types of mounting jaws, enabling both con- ventional tensile testing and compression testing to be performed. Strains and displacements were measured in- situ using an optical, non destructive method based on CCD imaging. The elastic constants of polymer (LCP), LCP-Au bi- layers and electroplated Ni were defined in good agreement with the literature. However yield of successfully released ceramic samples was rather poor so a col- laboration with IMTEK at Germany was established. Using their facilities batch processing of a large number of wafers was possible. Cont/d

The 2015 EU Survey on Industrial R&D Investment Trends

This tenth survey on industrial R&D investment trends is based on 162 responses of mainly large firms from a subsample of the 1000 EU-based companies in the 2014 EU Industrial R&D Investment Scoreboard. These 162 companies are responsible for €60 billion R&D investment, constituting around 36% of the total R&D investment by the 1000 EU Scoreboard companies. The responding companies expect to increase their nominal R&D investment by 3.0 % per year during 2015–17. This is a third less than the expected increases of last year’s survey (4.2 %) and slightly higher than the results of the one the year before (2.6 %). The responding companies carry out one-fourth of their R&D outside the EU. The responding companies’ expectations for R&D investment for the next three years show the ongoing participation of European companies in the global economy. While maintaining the focus of their R&D investment in the EU, they reap opportunities for growth in emerging economies. Three out of four of the responding EU-based companies consider their home country among the three most attractive locations for R&D. Regarding non-EU countries, the United States, China and India are seen as the most attractive locations outside the home country.JRC.J.2-Knowledge for Growt

EU regions and the upgrading for the digital age

In this work we use patent data from the European patent office (EPO) to assess the capabilities of EU regions in developing digital technologies especially focusing on those that are more closely related to the digital transformation. More specifically, we measure ICT patents by considering those containing digital codes, as defined by the OECD. The penetration of digital technologies in the development of innovative products is instead captured by the co-occurrence of digital and non-digital codes within patent documents; we call these patents ICT-combining patents.JRC.B.3-Territorial Developmen

Smart Specialisation, seizing new industrial opportunities

This study offers a novel analytical approach to inform the regional search for new industrial opportunities, as promoted by smart specialisation in the EU Cohesion policy context. The analysis departs from the challenges of practicing smart specialisation and its entrepreneurial discovery process in a dynamic perspective. It argues that the adoption of a dynamic approach to identify new opportunities implies mapping regional business and innovation assets as well as, assessing their position within the global technological and industrial landscape. The study brings a case study of Lombardy region, spurring the S3 Lab initiative (in collaboration with Baden-Württemberg, Catalonia and Lapland), together with a comparative analysis of its technological profile. The empirical study combines patent data from OECD REGPAT and territorial proprietary micro-data from Lombardy region on firm creation in emerging industries (EI) – new industrial sectors or existing sectors evolving into new industries (European Cluster Observatory). These industries represent a priority area for Lombardy's innovation-led development strategy. The initial observations confirm the importance of such industries in the region; they represent more than one-third of employment, almost a half of the regional value-added and feature together the majority of start-ups, suggesting the relevance of the regional strategic development choices. Also, in terms of productive advantages, Lombardy ranks high in some key EI. The mapping of technological competences through patent indicators, e.g. specialisation, diversification and ability to specialise in fast-growing and niche fields gives relevant insights on the technological potential of the region, providing further guidance for better targeted interventions.JRC.B.3-Territorial Developmen

World Top R&D Investors: Industrial Property Strategies in the Digital Economy

The speed, scale and scope of the digital transformation and the widespread use of digital technologies in most aspects of our daily lives are changing the way we work, innovate, produce, interact and live. Knowledge flows almost instantaneously and digitalised information can be infinitely replicated, making the exploitation of knowledge a key factor for competitiveness. At the same time, changes at the local level may have global implications and innovation ecosystems become more and more global. These dynamics challenge policy making, and call for understanding the drivers of change, detecting trends in a timely fashion, and acting in a coordinated manner. The internet of things, digital manufacturing and 3D printing, industry 4.0 and big data are all components and drivers of the digital transformation, but the ways in which this new technological revolution will transform industries, countries and societies remain difficult to fully anticipate. As we become increasingly aware of the opportunities and the challenges of the digital economy, we also need to better understand how these technologies are forged and to identify the key players in such changes. The original data and statistics on the innovation output of the world's top corporate R&D investors presented in this report and its focus on digital technologies represent an important step towards this direction. It results from a long-term collaboration between the European Commission's Joint Research Centre and the Organisation for Economic Co-operation and Development, and their joint efforts to provide up-to-date comparable data and state-of-the-art indicators and analysis. This report is directed at a number of stakeholders, including policy makers, industry representatives, practitioners and the scientific community. By exploiting information on patents, trademarks and designs, this work sheds light on the top R&D investors worldwide in the digital economy, their innovative and creative activities and their branding strategies. It is accompanied by a publicly available database that can be used for further analysis in support of evidence-based policy making.JRC.B.3-Territorial Developmen

Endoscopic removal of a toothpick perforating the sigmoid colon and causing chronic abdominal pain: a case report

Toothpick ingestion is implicated in gut injuries which may cause severe complications, mimicking diseases causing acute abdomen. However, toothpick ingestion-related perforation may also cause mild, non-specific gastrointestinal symptoms without significant findings or major complications. We describe a young male with chronic postprandial lower abdominal pain caused by a toothpick impaction at the rectosigmoid junction after inadvertent ingestion. The foreign body was detected and successfully removed during flexible sigmoidoscopy. Perforation due to foreign body ingestion must be considered in the differential diagnosis in patients presenting with unexplained symptoms and findings, even when they do not recall any foreign body ingestion
