University of Brighton Develops Affordable 3D-Printed Medical Sensors for Better Healthcare

 A Simpler and More Affordable Way to Make Medical Sensors

On 13th July 2026, researchers at the University of Brighton are developing a new generation of low-cost medical sensors that could make healthcare more affordable and accessible around the world. Led by Professor Bhavik Patel, the team has spent the last three years creating a simpler way to design and manufacture diagnostic sensors. Instead of depending on expensive equipment and specialized production facilities, the researchers use commonly available 3D printers and basic electronic parts. This approach significantly reduces manufacturing costs while making it easier for hospitals, laboratories, and research organizations to produce these devices. The team also focuses on using recyclable materials and environmentally friendly manufacturing methods, creating medical sensors that are both affordable and sustainable without reducing their performance.

New Sensors Could Improve Disease Detection

The research team has already developed several 3D-printed sensors for different medical conditions. One project, led by Dr. Chloe Miller, Biomedical Science graduate Athira Prasanth, and Professor Patel, produced a sensor that detects sugars in stool samples. The device costs less than ten pence to manufacture and has shown better accuracy than some traditional laboratory methods. It could help doctors diagnose intestinal malabsorption, a condition that prevents the body from properly absorbing nutrients. This condition can affect children, older adults, and people with bowel diseases. The sensor has already been tested using biological samples, and future studies will focus on confirming its effectiveness in clinical settings before it becomes available for routine medical use.

Professor Patel said: "Around the world, millions of people don't benefit from the latest diagnostic technologies because they're expensive to manufacture, require specialist equipment, or simply aren't practical to produce at scale. "We wanted to start again and ask a different question: what would a medical sensor look like if it were designed to be affordable, sustainable, and simple enough for almost anyone to manufacture? That's the challenge we've been working towards. "Accessibility isn't just about lowering the cost of a test. It's about making the technology itself easier to produce, easier to share, and ultimately easier for healthcare systems around the world to adopt."

Expanding Research Through National and International Collaboration

The University of Brighton has also created another 3D-printed sensor that detects TNFα, a protein linked to inflammation in the digestive system. Successfully tested in stool samples, the sensor may help doctors monitor inflammatory bowel disease and other gut disorders without invasive procedures. This research also supports the development of an implantable device that could continuously monitor bowel health while delivering medicines directly to affected areas. Beyond its own projects, the university is working with research partners across the United Kingdom and overseas. Together with the University of Strathclyde and the National Measurement Laboratory at LGC, the team helped develop a low-cost sensor that detects cardiac troponin, an important marker released during a heart attack. Another collaboration with the University of Naples Federico II produced a fully 3D-printed sensor capable of detecting tiny biological molecules linked to diseases such as lung cancer.

Opening New Possibilities for Global Healthcare

The University of Brighton hopes these innovations will make advanced diagnostic testing available to more people, especially in regions where healthcare resources are limited. Because the sensors are inexpensive, easy to produce, and require only commonly available equipment, healthcare providers could manufacture them locally instead of relying on costly imports. This could improve access to early disease detection while reducing delays in diagnosis. Their environmentally friendly design also helps reduce medical waste compared with many single-use diagnostic devices. As research continues, these technologies may support faster testing, lower healthcare costs, and more sustainable medical practices. The team's long-term goal is to create reliable diagnostic tools that can be produced almost anywhere in the world, helping hospitals, clinics, and laboratories deliver better patient care. If successfully adopted, these affordable sensors could strengthen healthcare systems, improve disease monitoring, encourage earlier treatment, and make quality diagnostics accessible to millions of people worldwide while supporting more sustainable medical innovation for future generations.

Professor Patel added: "Although each of these projects tackles a different health challenge, they're all built on the same idea: creating diagnostic technologies that are better for patients, better for the environment, and easier for the world to use. "Ultimately, we want to remove barriers. Whether someone is developing new diagnostics in Brighton, Birmingham, or a low-resource setting on the other side of the world, our vision is that these sensors should be simple to manufacture, affordable to produce, and straightforward to adapt for new diseases."
