Flexible Bioelectronic Devices are "Smart Bandages" for Chronic Wound Care

Some bandages are embedded with medicine to treat wounds, but researchers at Harvard University and Brigham and Women's Hospital have something more sophisticated in mind for the future of chronic wound care. With support from the National Science Foundation, engineer Ali Khademhosseini and a multidisciplinary team are bringing together advances in sensors, biomaterials, tissue engineering, microsystems technology, and microelectronics to create 'smart bandages' for wounds that require ongoing care - such as burns, diabetic ulcers, and bed sores. The new devices, known as flexible bioelectronics, will do more than deliver medicine. They will be able to monitor all the vital signs of the healing process, such as oxygen levels and temperature, and make adjustments when needed, as well as communicate the information to off-site health professionals. The team is testing new materials such as a hydrogel that would cover a wound with just the right amount of stretch to be comfortable.
