Long hospital stays can be difficult, and for many patients, they come with a hidden danger: pressure injuries.
These painful sores form when someone stays in the same position for too long, especially if there is moisture from sweating.
They can develop in just a few hours and are often hard to treat once they appear. In serious cases, they can even lead to infections or death.
Pressure injuries affect about 2.5 million people each year and are linked to around 60,000 deaths.
They can happen to a wide range of people, from elderly patients and wheelchair users to premature babies in intensive care. Even small issues, like a wrinkled bedsheet or misplaced medical tubing, can increase the risk.
Right now, prevention relies heavily on nurses and caregivers manually turning patients every few hours.
But this process is not always perfect, especially with ongoing staff shortages in hospitals. Missing even one repositioning can increase the risk of injury. The cost of treating these injuries is also very high, reaching nearly $27 billion each year in the United States alone.
To tackle this problem, researchers at the Georgia Institute of Technology have developed an innovative solution: a soft, flexible fabric filled with sensors that works like a smart bedsheet. This special fabric is placed under the patient and continuously monitors pressure and moisture on the skin.
The system quietly collects data without disturbing the patient. It can detect how long pressure has been applied to certain areas and whether moisture is building up—two key factors that lead to pressure injuries. By analyzing this information, the system can predict when a patient is at risk and alert healthcare staff to reposition them in time.
This technology is already being tested in a pediatric intensive care unit, where patients are especially vulnerable. Many children in these units are very sick, sedated, and unable to move on their own, which increases their risk. The new system aims to provide an extra layer of protection by giving timely, personalized alerts.
One of the biggest challenges in developing this system was making sure it was comfortable and safe, especially for fragile patients like premature babies. Earlier versions had many cables, but the latest design uses just one, making it easier to use and less intrusive.
Another exciting feature is the use of machine learning. The system can learn from each patient’s data, adapting to their weight, condition, and movement patterns. Over time, it becomes better at predicting risk and recommending the right care. In the future, it may even connect directly to hospital records and mobile apps, helping staff respond more quickly and efficiently.
Researchers hope this smart fabric could transform how hospitals prevent pressure injuries. Instead of relying only on manual care, healthcare workers could use real-time data to make better decisions.
If widely adopted, this simple but powerful technology could make pressure injuries far less common—and help ensure that patients leave the hospital healthier than when they arrived.
