Sensors for 'Smart' Wound Bandage Track Healing,
Immune Response
Wearable sensors monitor
certain biomarkers during
healing.
Skoltech, Moscow, Russia
Researchers from Skoltech and the
University of Texas at Austin have presented a proof-of-concept for a wearable
sensor that can track healing in sores,
ulcers, and other kinds of chronic skin
wounds, even without the need to
remove the bandages. The paper was
published in the journal ACS Sensors.
Chronic wounds that fail to heal quickly, such as diabetic foot ulcers or pressure

ulcers, can be very tricky to manage for
healthcare professionals and a nightmare for patients. To monitor the healing process and assess the need for treatment, doctors and nurses normally need
to remove the bandages from a wound,
which damages the recovering tissue,
often hurts the patient, and requires hospital visits, particularly to avoid further
infections. Furthermore, if a wound requires more than just visual inspection,
other available methods include tissue
biopsies, surface swabs, or testing for
pathogens - invasive and costly procedures that can take days and yet fail to
produce useful treatment directions.

That is why smart bandages, essentially wearable sensors that can monitor certain biomarkers during the healing
process, have captured the attention of
medical engineers. In the new study, the
Russia-U.S. team, led by Skoltech
provost Prof. Keith Stevenson, explored
electroanalytical methods that, thanks to
their relative simplicity, sensitivity, durability, and other attractive characteristics, are particularly promising for clinical applications.
