Pioneering project aims to revolutionise medical devices through adaptive 4D engineering

Researchers at the University of Birmingham and Imperial College London have launched a groundbreaking three-year initiative to advance the design and performance of medical devices by addressing the dynamic nature of the human body over time.

The project, titled 4D Engineering of Healthcare Technologies (4D Health Tech), seeks to fundamentally rethink how medical devices are developed by integrating the concept of time as a critical design factor. The goal is to improve the adaptability, longevity, and functionality of medical technologies as individuals grow, move, heal, and age.

Dr Sophie Cox, project lead from the University of Birmingham, explained:

“Our bodies change over time as we grow, move and regenerate, but products designed to replace or repair our bodies typically neglect the dimension of time, compromising their function and lifespan. Our vision is to transform the way we engineer medical devices.”

Traditional medical devices are often static in design, unable to respond effectively to gradual physiological changes. For example, implants for children must be replaced as they grow, while adult bone implants may not degrade in harmony with tissue regeneration. These limitations can lead to reduced effectiveness, increased risk of complications, and the need for repeated surgical interventions.

The 4D Health Tech project will explore innovative approaches to these challenges by promoting the development and use of materials that degrade in a controlled and predictable manner. Such materials could enable devices to better support healing processes, reduce the need for replacement surgeries, and align more closely with individual recovery patterns.

In addition to novel materials, the project will investigate advanced design methodologies, state-of-the-art manufacturing techniques, and patient-specific testing protocols. The aim is to create adaptable medical technologies that reflect the diversity of the population and provide improved outcomes across the lifespan.

Crucially, the inclusion of time as a “fourth dimension” in medical engineering represents a significant shift in how devices are conceptualised and built. By accounting for time-dependent biological changes, researchers hope to unlock new functionalities in medical technologies and significantly extend their usable life. This could not only benefit individuals receiving care but also contribute to more efficient use of resources within the NHS.

The project is backed by £1.2 million in funding from the Engineering and Physical Sciences Research Council (EPSRC), part of UK Research and Innovation (UKRI). It is one of several projects supported under a broader £10 million investment in response to the Tomorrow’s Engineering Research Challenges (TERC) report. This report identifies key areas in which engineering research can support the UK’s long-term economic, environmental, and societal priorities.

Jane Nicholson, Executive Director for Research at EPSRC, commented:

“Engineering is the cornerstone to a more sustainable, successful and thriving future for the UK. From developing renewable energy solutions to creating smart cities, engineering innovations are driving progress in every sector. These new networks will address the strategic challenges outlined by the TERC report. Together, these researchers present a hugely ambitious, thoughtful response to the economic, environmental and social challenges we all face.”

The launch of the 4D Health Tech initiative aligns with recent national developments in medical technology regulation and evaluation. In February 2025, the National Institute for Health and Care Excellence (NICE) announced a public consultation on proposed changes to its HealthTech programme, which aims to streamline the evaluation of innovative medical technologies for adoption within the NHS.

This follows updated guidance issued in January 2025 by the Medicines and Healthcare Products Regulatory Agency (MHRA), intended to assist medical device manufacturers in preparing for new post-market surveillance (PMS) regulations. These regulations, which come into effect on 16 June 2025, are designed to ensure ongoing safety and performance monitoring of medical technologies in clinical use.

Together, these policy shifts and research initiatives signal a growing national commitment to fostering innovation in medical technology, ensuring that future devices are not only cutting-edge, but also responsive to the complex and evolving needs of people receiving care.
