About Smart Bandage:

  • A smart bandage is a type of bandage made from a soft and stretchable polymer that adheres to the skin.
  • It incorporates a bioelectronics system with biosensors to monitor biomarkers present in wound exudate.
  • The bandage collects data from the wound and transmits it wirelessly to a smartphone or tablet for review by a healthcare professional.
  • It includes a hydrogel layer with drug-release capabilities and the ability to stimulate tissue regrowth using a pair of electrodes.

How does it work?

  • Biosensors within the smart bandage analyze the chemical composition of the wound exudate, which changes as the wound heals, providing information about the wound status.
  • Additional sensors monitor parameters like pH and temperature in real-time to detect signs of infection and inflammation.
  • The bandage’s pair of electrodes not only stimulate tissue regrowth but also control the release of drugs from the hydrogel layer.
  • The wireless functionality of the smart bandage eliminates the need for bulky equipment and wired connections, addressing limitations of existing electrical stimulation devices and increasing its clinical usability.
