The proposed EPSRC Centre for Doctoral Training in Sensor Technologies in an Uncertain World (Sensor CDT) will educate leaders who can effectively address the challenges of an increasingly uncertain, complex, and interconnected world. In recent years, society has faced a global pandemic, an energy crisis, and the consequences of war and the climate crisis. Sensor technologies play a vital role in addressing these challenges. They are essential tools for detecting changes in the world, protecting livelihoods, and improving well-being. Accurate sensory data are crucial for informing the public and enabling governments and policymakers to make evidence-based decisions. The new Sensor CDT is designed to train and inspire future sensor leaders with interdisciplinary and agile thinking skills to meet these challenges. Our students will learn to collaborate within and across cohorts, and co-create solutions with key stakeholders, including other scientists, industry partners, the third sector, and the public. The fully integrated 4-year Master + PhD program will be co-delivered by over 80 leading academics, over 25 industrial partners, and national research and policy agencies, and will cover the entire sensor value chain, from development over deployment and maintenance to end-of-life including middleware, and big data. Within the broader theme of uncertainty, we have identified three Focus Areas: I) Uncertainty in Sensory Data. According to the environmental sensor report published by UKRI in 2022, "data quality remains a major concern that hinders the widespread adoption of low-cost sensor technology". Through bespoke training in measurement science, statistical methods and AI, our students will learn to determine data quality and interpret imperfect, uncertain and constantly changing data. By acquiring hands-on design and prototyping skills and familiarising themselves with ubiquitous open technology platforms, they will learn how to construct more accurate and reliable sensors. II) Sensors in an Uncertain World. Environmental, economic and social uncertainties disproportionately impact low- and mid-income countries. Through collaboration with academic partners and policy agencies, the students will explore the impact of these interconnected uncertainties and pathways through which they can be mitigated by deploying low-cost sensor technologies. III) Uncertainty in Industry. UK industries deal with uncertainties in supply chains, variable process conditions and feedstocks, and they are subject to changing regulatory guidelines. Sensor data are critical to minimise the effect of such uncertainties on the quality of products and services. Through the provision of training in technical skills, systems thinking, leadership, and project management, our students will learn to innovate on rapidly changing timelines, and to work increasingly in collaboration and synergy with stakeholders in commerce and the public. Whilst prevention of future disasters is important, we recognise an increasing need to create resilience in a world facing rapid, often irreversible, change. Solutions must be co-created with society. The CDT will equip students with the confidence to collaborate across a range of fields, including arts and social sciences, skills that cannot be acquired in traditional, single student / single discipline PhD programmes. Finally, our programme will address a skills gap identified by UK industry and academia, who report a growing problem in recruiting suitably qualified candidates with the skills, disciplinary breadth and leadership qualities needed to drive innovation in the sensor field. In the UK alone, the sensor market contributes to ~£6bn in exports, underpins ~70,000 jobs, and connects to a global market estimated to reach £500bn in 2032 (Sensors KTN). Providing the skilled talent for the UK to succeed in this rapidly growing and competitive sector is a crucial goal of our programme.

We propose to build the EPSRC Centre for Doctoral Training in Sensor Technologies for a Healthy and Sustainable Future (Sensor CDT) on the foundations we have established with our current CDT (EPSRC CDT for Sensor Technologies and Applications, see http://cdt.sensors.cam.ac.uk). The bid falls squarely into EPSRC's strategic priority theme of New Science and Technology for Sensing, Imaging and Analysis. The sensor market already contributes an annual £6bn in exports to the UK economy, underpinning 73000 jobs and markets estimated at £120bn (source: KTN UK). Major growth is expected in this sector but at the same time there is a growing problem in recruiting suitably qualified candidates with the necessary breadth of skills and leadership qualities to address identified needs from UK industry and to drive sustainable innovation. We have created an integrated programme for high quality research students that treats sensing as an academic discipline in its own right and provides comprehensive training in sensor technologies all the way from the fundamental science of sensing, the networking and interpretation of sensory data, to end user application. In the new, evolved CDT, we will provide training for our CDT students on themes that are of direct relevance to a sustainable and healthy future society, whilst retaining a focus that delivers value to the UK economy and academia. The 4-year programme is strongly cross disciplinary and focuses on sustainable development goals and emphasises training in Responsible Innovation. One example of the latter is our objective to 'democratise sensor technologies': Our students will learn how to engage with the public during research, how to play a valuable part in public debate, and how to innovate technology that benefits society. Technical aspects will be taught in a bespoke training programme for the course, that includes lectures, practicals, lab rotations, industry secondments, and skills training on key underpinning technologies. To support this effort, we have created dedicated, state-of-the-art infrastructure for the CDT that includes laboratory, office, teaching, and social spaces, and we connect to the world leading infrastructure available in the participating departments and partner industries. The programme is designed to create strong identities both within and across CDT cohorts (horizontal and vertical integration) to maximise opportunities for peer-to-peer learning and leadership training through activities such as our unique sensor team challenges and the monthly Sensor Cafés, attended by representatives from academia, industry, government agencies, and the public. We will create a diverse and inclusive atmosphere where students feel confident and empowered to offer different opinions and experiences and which maximises creativity and innovation. We have attracted substantial interest and support (>£2.5M) from established industrial partners, but our new programme emphasises engagement also with UK start-ups and SMEs, who are particularly vulnerable in the current economic climate and who have expressed a need for researchers with the breadth and depth of skills the CDT provides (see letters of support). We recruit outstanding, prizewinning students from a diverse range of disciplines and the training programme connects more than 90 PIs across 15 departments and 40 industrial partners working together to address future societal needs with novel sensor technologies. Technology developers will benefit through connection with experts in middleware (e.g. sensor distribution and networking, data processing) and applications experts (e.g. life scientists, atmospheric scientists, etc.) and vice versa. This integrative character of the CDT will inspire innovations that transform capability in many disciplines of science and industries.
