The emergence of a global ubiquitous computing environment in which each of us routinely interacts with many thousands of interconnected computers embedded into the everyday world around us will transform the ways in which we work, travel, learn, entertain ourselves and socialise. Ubiquitous computing will be the engine that drives our future digital economy, stimulating new forms of digital business and transforming existing ones.However, ubiquitous computing also carries considerable risks in terms of societal acceptance and a lack of established models of innovation and wealth creation, so that unlocking its potential is far from straightforward. In order to ensure that the UK reaps the benefits of ubiquitous computing while avoiding its risks, we must address three fundamental challenges. First, we need to pursue a new technical research agenda for the widespread adoption of ubiquitous computing. Second, we must understand and design for an increasingly diverse population of users. Third, we need to establish new paths to innovation in digital business. Meeting these challenges requires a new generation of researchers with interdisciplinary skills in the technical and human centred aspects of ubiquitous computing and transferable skills in research, innovation and societal impact.Our doctoral training centre for Ubiquitous Computing in the Digital Economy will develop a cohort of interdisciplinary researchers who have been exposed to new research methods and paradigms within a creative and adventurous culture so as to provide the future leadership in research and knowledge transfer that is necessary to secure the transformative potential of ubiquitous computing for the UK digital economy. To achieve this we will work across traditional research boundaries; encourage students to adopt an end-to-end perspective on innovation; promote creativity and adventure in research; and place engagement with society, industry and key stakeholders at the core of our programme.Our proposal brings together a unique pool of researchers with extensive expertise in the technologies of ubiquitous and location based computing, user-centred design, societal understanding, and research and training in innovation and leadership. It also involves a wide spectrum of industry partners from across the value chain for ubiquitous computing, spanning positioning, communications, devices, middleware, databases, design, and our two driving market sectors of the creative industries and transportation.Our training programme is based on the approach of personalised pathways that develop individual students' interdisciplinary and transferable skills, and that produce a personal portfolio to showcase the skills and experience gained alongside the more traditional PhD thesis. It includes a flexible taught programme that emphasises student-led seminars, short-fat modules, training projects and e-learning as delivery mechanisms that are suited to PhD training; an industrial internship scheme under which students spend three months working at an industrial partner; and a PhD research project that builds on a proposal developed during the first year of training and that is supported by multiple supervisors from different disciplines with industry involvement. Our DTC will foster a community of researchers through a dedicated shared space, a programme of community building events, training for supervisors and well as students, funding for a student society, and an alumni programme.

Graphene (a single atomic layer of graphite) first experimentally isolated and identified only four years ago, is rapidly revealing its great potential as an important material for future electronic devices. In order to progress towards realistic device applications of graphene, it is important to address the issues which will affect the operation of graphene in real circuits, where high currents will lead to overheating and non-equilibrium charge carrier distributions. The proposed joint project will launch an internationally leading programme involving three research groups which are already well established in graphene research and have expertise in complimentary areas. By combining fabrication technology of graphene-based devices, transport and optical studies, and theoretical modelling, we will investigate the kinetic properties of charge carriers and phonons (lattice vibrations) in graphene over a broad range of operating voltages, temperatures and optical intensities, with the aim to establish and improve the operating characteristics of graphene-based electronic and optoelectronic devices.

Graphene has many record properties. It is transparent like (or better than) plastic, but conducts heat and electricity better than any metal, it is an elastic thin film, behaves as an impermeable membrane, and it is chemically inert and stable. Thus it is ideal for the production of next generation transparent conductors. Thin and flexible graphene-based electronic components may be obtained and modularly integrated, and thin portable devices may be assembled and distributed. Graphene can withstand dramatic mechanical deformation, for instance it can be folded without breaking. Foldable devices can be imagined, together with a wealth of new form factors, with innovative concepts of integration and distribution. At present, the realisation of an electronic device (such as, e.g., a mobile phone) requires the assembly of a variety of components obtained by many technologies. Graphene, by including different properties within the same material, can offer the opportunity to build a comprehensive technological platform for the realisation of almost any device component, including transistors, batteries, optoelectronic components, photovoltaic cells, (photo)detectors, ultrafast lasers, bio- and physico-chemical sensors, etc. Such change in the paradigm of device manufacturing would revolutionise the global industry. UK will have the chance to re-acquire a prominent position within the global Information and Communication Technology industry, by exploiting the synergy of excellent researchers and manufacturers. We propose a programme of innovative and adventurous research, with an emphasis on applications, uniquely placed to translate this vision into reality. Our research consortium, led by engineers, brings together a diverse team with world-leading expertise in graphene, carbon electronics, antennas, wearable communications, batteries and supercapacitors. We have strong alignment with industry needs and engage as project partners potential users. We will complement and wish to engage with other components of the graphene global research and technology hub, and other relevant initiatives. The present and future links will allow UK to significantly leverage any investment in our consortium and will benefit UK plc. The programme consists of related activities built around the central challenge of flexible and energy efficient (opto)electronics, for which graphene is a unique enabling platform. This will be achieved through four main themes. T1: growth, transfer and printing; T2: energy; T3: connectivity; T4: detectors. The final aim is to develop "graphene-augmented" smart integrated devices on flexible/transparent substrates, with the necessary energy storage capability to work autonomously and wireless connected. Our vision is to take graphene from a state of raw potential to a point where it can revolutionise flexible, wearable and transparent (opto)electronics, with a manifold return for UK, in innovation and exploitation. Graphene has benefits both in terms of cost-advantage, and uniqueness of attributes and performance. It will enable cheap, energy autonomous and disposable devices and communication systems, integrated in transparent and flexible surfaces, with application to smart homes, industrial processes, environmental monitoring, personal healthcare and more. This will lead to ultimate device wearability, new user interfaces and novel interaction paradigms, with new opportunities in communication, gaming, media, social networking, sport and wellness. By enabling flexible (opto)electronics, graphene will allow the exploitation of the existing knowledge base and infrastructure of companies working on organic electronics (organic LEDs, conductive polymers, printable electronics), and a unique synergistic framework for collecting and underpinning many distributed technical competences.

Analysis and diagnosis, the core elements of sensing, are highlighted by almost every initiative for health, environment, security and quality of life. Sensors have advanced to an extent that they are sought for many applications in manufacturing and detection segments, and their cost advantages have boosted their utility and demand. The pillars of sensor research are in highly diverse fields and traditional single-discipline research is particularly poor at catalysing sensor innovation and application, as these typically fall in the 'discipline gaps'. Furthermore, the underpinning technology is advancing at a phenomenal pace. These developments are creating exciting opportunities, but also enormous challenges to UK academia and industry: Traditional PhD programmes are centred on individuals and focused on narrowly defined problems and do not produce the skills and leadership qualities required to capitalise on future opportunities. Industry complains that skills are waning and sensors are increasingly being treated as 'black boxes' without an understanding of underlying principles. We propose to establish the EPSRC Centre for Doctoral Training in Sensor Technologies and Measurement to address these problems head on. The CDT will provide a co-ordinated programme of training in research-, team-, and leadership-skills to future generations of sensor champions. The CDT will build on the highly successful CamBridgeSens research network which was previously funded by the EPSRC under its discipline-bridging programme and which has transformed the culture in which sensor research is being carried out at our University, breaking down discipline barriers, and bringing together world-leading expertise, infrastructure and people from more than 20 Departments. The CDT will now extend this culture to the training of future sensor researchers to generate a virtual super department in Cambridge with more than 70 PIs. The programme will be underpinned by a consortium of industrial partners which is strongly integrated into the CDT and through its needs and engagement will inform the direction of the programme. In the first year of their 4 year PhD programme, student cohorts will attend specialised lectures, practicals and research mini-projects, to receive training in a range of topics underpinning sensor research, including physical principles of sensor hardware, acquisition and interpretation of sensory information, and user requirements of sensor applications. Team-building aspects will be strongly emphasised, and through an extended sensor project treated as a team challenge in the first year of their programme, the students will together, as a cohort, face a problem of industrial relevance and learn how to address a research problem as a team rather than individually. The cohorts will be supported by a mix of academic and industrial mentors, and will receive business, presentation and project-management skills. During years 2 to 4 of their PhD course, students will pick a PhD topic offered by the more than 70 PIs participating in the programme. Each topic on offer will be supervised by at least two academics from different departments/disciplines and may include industrial partners in the CDT. Throughout, we will create strong identities for the sensor student cohorts through a number of people-based activities that maximise engagement between researchers, research activities and that bridge gaps across disciplines, Departments and research cultures.

Topic of centre: Assembly of Functional NanoMaterials and NanoDevices, the focus of this training centre, aims to make significant progress in developing new functional NanoScience and NanoTechnologies for impact in four major areas: Energy Materials, Sustainable NanoMaterials, Nano-Bio Technologies, and NanoElectronics/Photonics. Each of these connects to strong societal challenges, which can be unlocked by critical advances in nano-assembly. The synergistic overlap of the underlying nano-assembly knots all these areas together so they act to pull early-stage overarching developments in clear application directions. Harnessing a massive existing collaboration of >150 interdisciplinary academics and promoting new interactions across the University of Cambridge, we can translate nascent science into real innovation, through the endeavour and focus of the cohorts within this CDT. National Need: Most breakthrough nanoscience relies on scientists bridging disciplinary boundaries. In the UK approach to science training, most graduates selecting PhDs never leave the comfort of their original discipline. Producing a cadre of interdisciplinary nanoscientists is crucial for the UK to develop both the new academic directions and the industrial capabilities to capitalise on the ideas emerging from the fertile ground of Nanoscience. This CDT opens the way to achieve this so that PhD students move into new departments. Our numerous industrial partners strongly emphasise that such broadly-trained interdisciplinary acolytes are highly valuable across their businesses, acting as transformers and integrators of new knowledge, crucial for the UK. These will be trained people in high demand. Approach: The aim of this CDT in Nano is to attract a world-class team of postgraduates and build a high-calibre cohort of self-supporting young Nano scientists bridging our themed areas. The Nano CDT will operate as a distinct PhD nursery, with the entry co-housed and jointly mentored in the initial year of formal courses and project work. It is crucial to develop a programme that encourages young researchers to move outside their core disciplines, and that goes well beyond the fragmented graduate training normally experienced. The 1st year provides high-quality advanced-level training prior to final selection of preferred research projects. Four components are important: - learning additional skills in disciplines outside their 1st degree, including over 30 hands-on practicals in small groups, directly making and characterising nanomaterials and devices. - understanding the Enterprise landscape relating to Nano-Innovation, gaining confidence and know-how for spin-outs, partnering, and what is critical in building high-tech spin-off companies, - gaining specific knowledge of the nanoscience and application of self-assembly to NanoDevices and NanoMaterials, including nano-forces, nano-wetting, commercial nano processing, etc. - miniprojects spanning different disciplines to broaden students' experience and peer networks, aiding final PhD project selection. Three 2-3 month-long interdisciplinary mini-projects within different departments will be undertaken by each student. This coursework is examined leading to an MRes. Students will develop their own PhD topics during interactions with academics across the University and industrial mentors. Students express interest in a ranked list of top 3 projects, and are allocated approval to start building a case around a topic with the two supervisors involved. They are examined in a written proposal, and then a formal viva on the aims, methodologies and technical issues. To prevent the subsequent pressures of research draining the cohort dynamics, a range of joint activities are programmed in later years. Additional exposure includes industrial research reviews, a series of mandatory internal (student-led) conferences, leadership and team-building weekends, and research seminars.
