SINGAPORE - A paper-thin sensor patch the size of a postage stamp attached to the skin could soon help to determine how well a wound is healing, without the need to remove its dressing.
The innovation was developed by researchers from the National University of Singapore and the Agency for Science, Technology and Research’s Institute of Materials Research and Engineering . Prof Tee, the principal investigator for the research, added that wound dressing such as bandages could lead to infections if done improperly.
It also requires wound dressing to be removed regularly, which can increase the risk of infection as well as cause additional pain for patients. The patch collects fluid from the wound and distributes it to the five sensors, which change colours to show the levels of these indicators.
