Description

Expected Outcome:

Photonic sensor technologies enable precision and versatility in sensing across multiple domains. The integration into multimodal systems enhances data accuracy, speed and reliability. Advancements in photonic sensors and their multimodal integration aim to elevate diagnostics, monitoring, and sensing by improving efficiency, performance, and reliability while reducing size and manufacturing costs and power consumption.

The development of sensor technologies and multimodal integration is closely aligned with several key EU policies. These include achieving open strategic autonomy in digital and emerging enabling technologies, enhancing Europe's technological sovereignty, and supporting the twin transition to a digital and green economy by promoting energy-efficient, competitive, and resilient digital infrastructures.

The initiative also aims to advance the digital transformation by providing access to high-quality environmental data, supporting the development of technologies for privacy, compliance, and data integrity to empower decision-making and foster a fair data economy.

Lastly, it contributes to the green transition by leveraging photonic sensor technologies for environmental monitoring and sustainable practices. It aligns with the EU's objectives for a green and digital economy, enhancing system operations and promoting innovation in eco-friendly practices, thus strengthening Europe's technological leadership for societal and economic progress.

Projects are expected to contribute to at least three of the following outcomes to fully exploit the potential of photonics for a digital, green and healthy future in Europe:

  • Increase the efficiency of developed photonic sensors, surpassing existing technologies in aspects such as energy consumption, data acquisition and processing speed, as well as measurement accuracy.
  • Significantly reduce the size, weight, or footprint of the sensors and quantify advancements over current technologies.
  • Improve both intrinsic and extrinsic performance metrics to boost measurement accuracy for at least three use-case scenarios.
  • Extend the sensing and testing capabilities of photonic sensors by linking optical with non-optical measurement parameters (e.g. for acoustic sensing or electromagnetic sensing).
  • Contribute to reducing manufacturing costs and increasing resource-efficiency, while also enhancing reliability and durability of the targeted sensor systems.

They are additionally expected to:

  • Help secure the open strategic autonomy for Europe by ensuring intellectual property and production means of key technologies are maintained within the EU, reducing dependencies and enhancing negotiation power in technological cooperation.
  • Help maximise international competitiveness by increasing the uptake and translation of photonic technologies into new products and services, guided by key technology requirements.
Scope:

The scope of this topic focuses on the advancement and application of photonic sensor technologies and their integration into multimodal systems. Proposals are expected to address the development of sensor technologies and their validation through trials in realistic use cases. This includes exploring multi-modal sensor capabilities, as well as employing sensor fusion and machine learning approaches for the analysis of sensor data. Techniques should address at least two different technology approaches, i.e. sensor modalities, of which at least one must be photonic from the following areas:

  • 3D sensing and imaging such as LIDAR, optical coherence tomography (OCT), optical tomography, interferometry, photoacoustics, etc.
  • Communication fiber sensing
  • Chemical and gas sensing   
  • Bio- and medical sensing and/or imaging  
  • Particle sensing   
  • Integrated photonic solutions

In addition, the proposals could focus on developing and integrating algorithms designed to enhance the processing capabilities and decision-making accuracy of photonic sensors. These algorithms may help to optimize the interpretation of complex sensor data, enable real-time analytics, ambient intelligence and adaptive responses in dynamic environments.

Furthermore, projects should aim to provide significant improvements in one or more of the application domains listed below and to demonstrate these in at least three use case scenarios. Demonstrators would be expected to reach TRL 4-5 while the photonic techniques would be developed up to TRL 7.

This expectation underlines the call's objective to foster innovations that have a substantial and beneficial impact on society and various industry sectors:

  • Healthcare (medical diagnostics, disinfection, treatment through improved imaging techniques and diagnostic accuracy).
  • Transportation Safety (enhanced safety features in automotive and aerospace industries through better sensing capabilities).
  • Industrial efficiency and sustainability (industrial processes such as manufacturing, quality control, increasing precision and automation through improved sensing technologies).
  • Agricultural/Food Sector (precision agriculture, food safety, food waste reduction and supply chain management through improved sensing techniques for monitoring crop health, detecting contaminants, and optimizing production processes and raw material utilisation).
  • Environmental Monitoring and sustainable energy (pollution monitoring, climate research, renewable energy infrastructure and natural disaster mitigation).
  • Security, safety and resilience of people and critical infrastructure (face identification, long distance observation by day and night, (infra-)structural health monitoring, chemical and gas sensing, explosive detection)
  • Protection and efficient operation of optical communications, risk management of data transport and processing including increased resilience to cyber security.

Proposals submitted under this topic should include a business scenario and exploitation strategy.

Research must build on existing standards or contribute to standardisation. Where relevant, interoperability for data sharing should be addressed.

All projects should build on or seek collaboration with existing projects and develop synergies with other relevant European, national or regional initiatives, funding programmes and platforms, in particular the Digital Europe Programme (DEP).

Destination & Scope

Destination 4 ensures Europe’s strategic autonomy while preserving an open economy in those technologies that will be key for a deep digital transformation of industry, public services and society, while fully playing its enabling role in the twin transition. As set out in the European Chips Act, the top-priorities are to i) strengthen processes undertaken at critical stages in the semiconductor and quantum chips value chain, including chip design and manufacturing technologies, and ii) address the use of new materials and green technologies, energy efficiency and the integration of circularity and life-cycle assessment.

Destination 4 will address high value-added hardware needs for core, cloud and edge, fast-sensing, low-latency and high-bandwidth data transmission, and help secure the supply of critical components for key markets, such as automotive, health, automation and mobility systems. For this purpose, significant human capacity will be required in chip manufacturing to ensure: (i) the strengthening of processes undertaken at critical stages in the value chain; and (ii) that workers can take up quality jobs created as part of these priorities, including through the activities undertaken by the joint undertaking initiative.

In addition, future needs in microelectronics (such as performance, size, cost, energy efficiency, environmental impact, new materials, concepts, architectures, integration) may also be addressed to make sure Europe’s microelectronics industry remains competitive. Opportunities may come from non-volatile memories, spintronics, in-memory computing, neuromorphic and other emerging technologies. Photonics research will lead to fast and versatile sensing and imaging, and energy-efficient building blocks for networks and data centres. The cluster will also push for chip-level integration of photonics and optoelectronics.

The cloud/edge/internet of things will be transformed into an agile and situation-aware infrastructure that brings data to where and when it is needed. Within these smart digital infrastructures, end-to-end artificial intelligence, from the core to the edge and across all technology layers, will be key for on-demand supply of optimal data-, communication-, and computing resource orchestration, with optimal use of energy while preserving privacy and ensuring resilience. European sovereignty in the cloud-edge server market will be strengthened through the power of open-source software, complementing the RISC-V based European Processor Initiative that aims to increase Europe’s independence in high performance computing hardware.

Cluster 4 will transform the user experience. It will push the frontiers of virtual and extended realities (VR/XR) and of open, human-centric virtual worlds for industry, entertainment and arts, public services and people alike, e.g. by leveraging social innovation. It envisages a vibrant R&I ecosystem that strategically joins-up research and development on sophisticated VR/XR optics and displays, multimodal human-computer interaction, authoring tools, real-time spatial computing, rendering, integration and application research. Improved sensing, fast processing and low-latency will be challenging for the underlying cloud/edge/Internet of things. Along similar lines, the way in which the virtual world meets the physical world will continue to evolve, thanks to all kinds of robots and other smart devices that involve self- and context awareness, spatial intelligence, exploiting the best in bias-free AI, engineering and design for game-changing physical characteristics, functional or cognitive capabilities, acute perception, autonomy and safe interaction.

Artificial intelligence underpins many of these changes and Cluster 4 will strengthen and consolidate R&I in this area. For example, today’s generative models are a preview of how virtual worlds and multimodal user-experiences could be produced on-demand. Research on core learning and analysis techniques (incremental, frugal and collaborative), as well as next generation smart robotic systems, will keep Europe at the cutting edge of AI. Artificial Intelligence is also key to keep the competitiveness and strategic autonomy of the EU scientific sector. The EU's comprehensive approach to achieving leadership in AI is reflected in its Apply AI Strategy, which aims at establishing Europe as a global leader in the development and adoption of AI. By fostering a vibrant AI ecosystem, the EU seeks to make Europe a hub for AI innovation and growth, where world-class AI models are developed and integrated into strategic sectors. This initiative is designed to drive innovation, economic growth, and competitiveness, while ensuring that the benefits of AI are shared by all. The topics related to Generative AI included in this destination will support the implementation of the GenAI4EU initiative included in the AI Innovation Package of 24 January 2024. They constitute, moreover, an integral part of the broader Apply AI strategy. By aligning these efforts with the GenAI4EU initiative and the Apply AI strategy, the EU aims to create a cohesive and coordinated approach to AI development and adoption, one that promotes European excellence and leadership in this critical field.

Europe’s long-term competitiveness in the digital area requires continuous scouting and early, low-TRL cross-disciplinary work on new and emerging technologies, dissociated from the main roadmaps. This would encourage collaboration in research and cross-fertilisation between disciplines and sectors on new approaches in: (i) microelectronics; (ii) power electronics; (iii) photonics and photon/phonon/spin/electron integration; (iv) unconventional, hybrid, neuromorphic, nature-inspired or bio-intelligent paradigms; and (v) novel systems and infrastructure architectures.

Europe’s strength in quantum technologies (including in quantum communications and optical satellite communications, etc.) is a strategic asset for its future security and independence. Cluster 4 supports early and mature quantum technologies and stimulates their industrial uptake, e.g. through experimentation and testing environments for integrating them into standard industrial design and manufacturing. Equally transformative, two-dimensional materials (2DM) could positively affect many industries, including ICT. While further exploring the vast range of 2DMs, Cluster 4 will also work towards completing a fully European supply chain and scaling up the development and piloting of 2DM technologies and devices for more industrial fields.
