A Smart Bandage to Detect and Monitor a Pressure Ulcers

News- Researchers at Missouri S&T are developing an oxygen-sensing patch printed on a flexible, disposable bandage that could enable remote monitoring for the early detection of pressure ulcers

“Our current work focuses on designing and optimizing a tissue oxygen sensor by using inexpensive inkjet printing techniques,” says Dr. Chang-Soo Kim, professor of electrical and computer engineering at Missouri S&T. “Concurrently, we are developing a smartphone app that can interpret sensor images

Generally, ulcer injuries must be assessed manually and evaluated by medical personnel. But a smart dressing could sense the impaired blood circulation and poor oxygenation around the at-risk skin region. “Our optical sensor bandage functions by detecting a low skin oxygen level caused by compromised circulation,” says Kim. “This low oxygen produces a color change called luminescence intensity. The smartphone can then take a photograph of the dressing and transmit it for patient’s care provider to enable remote monitoring or encourage timely intervention before major skin decomposition occurs.”
