Recently, a research team from the University of Nottingham Ningbo China (UNNC) published groundbreaking results in the internationally prestigious journal ACS Applied Materials & Interfaces, announcing the successful development of a novel multi-modal wearable patch (MMWP) for post-operative skin flap transplantation.
This patch enables real-time monitoring of four key parameters, swelling, temperature, humidity, and percutaneous arterial oxygen saturation(SpO2), providing a comprehensive and dynamic analysis of the recovery process after flap transplantation surgery for clinicians, while eliminating the risk of secondary injuries caused by traditional gauze removal.
The patch measures 20 mm by 20 mm with a thickness of under 1 mm. Its flexible material and microsensor-based "tic-tac-toe" pattern allow full-area monitoring of transplanted skin. When sudden drops in SpO2 or abnormal temperature occur, Bluetooth-enabled alerts notify clinicians of potential vascular blockages or infections. With a 14-day battery life and resistance to bending, the device significantly enhances clinical practicality.
Led by UNNC PhD student Jie Luo and completed under the interdisciplinary guidance of Professor Haonan Li and Assistant Professor Sze Shin Low, both of whom are among the top 2% of scientists globally, the research team addressed clinical needs by integrating laser-induced graphene (LIG) technology and overcame technical challenges in 18 months. Jie Luo said, "UNNC's state-of-the-art research facilities, international academic resources, and robust funding provide critical support for the development. "
Currently, the team is optimising the device's performance, aiming to reduce sensor thickness to the micrometre scale and improve sensitivity through nanomaterial integration. This innovation marks a transformative step in global medical technology, offering new pathways for precision post-operative care.
