They created a futuristic shoe that prevents the elderly from falling.
Falls are the world's second leading cause of unintentional injury death, as well as one of the leading causes of hospital admissions in people over 65.
The problem is not limited to the medical aspect only, as the fall may end the independent life of a person who was self-reliant until that point.
A researcher at the University of Bristol, Dr. Jiayang Li, a professor of electrical engineering, has developed a prototype aimed at solving this problem.
His project began after he noticed his mentor, 89-year-old Peter Langlois, losing his balance one day.
This situation was enough to make Jiayang Li wonder whether the semiconductor technology he had been working on for years could have a direct application in the lives of people like him.
The device designed by Dr. Jiayang Li looks like a traditional shoe, but its sole contains 253 tiny sensors connected to a chip that was developed specifically for this project.
It is worth noting that the processor is capable of reading all sensor data simultaneously and processing the data in real time, producing detailed images of the foot that identify pressure points and assess whether the gait shows signs of instability.
The information is transmitted wirelessly to a mobile device, where it can be accessed without the need for medical equipment. Furthermore, the microchip consumes only 100 microwatts of power, allowing for continuous use for up to three months without recharging.
The scientist had previously worked on similar sensors used to study lung function, in collaboration with University College London. The logic was applicable in other areas: if it was possible to accurately map how a person breathes, it was also possible to map how they walk.
It is important to note that advanced gait analysis for fall risk detection is not a new technique, but until now it has required medical equipment.
In fact, the real achievement of this prototype lies in integrating this technology into a shoe sole that can be worn anytime, anywhere.
A device that can save lives
The prototype was unveiled on February 18 during the International Solid-State Circuits Conference (ISSCC 2026), organized by the Institute of Electrical and Electronics Engineers (IEEE) in San Francisco, USA.
This conference is one of the world's leading forums for technological innovation in circuits and was attended by representatives from leading companies such as Nvidia, Samsung, and Intel. Dr. Lee's research paper was the only one presented at the conference led entirely by a British scientist.
The next step is to conduct a formal clinical evaluation with a larger and more diverse user group to verify the system's ability to accurately predict falls. This will be followed by collaboration with partners in the clinical and industrial sectors to scale up production.
It should be noted that the prototype exists and has strong support, but there is still a long way to go. Clinical validation, the manufacturing chain, and the final cost to the consumer are all variables that have yet to be determined.
If these problems are solved, this shoe could represent a major change in approach, moving from dealing with the consequences of a fall to anticipating them with a device on the foot and three months of autonomy on a single charge.
