Abstract
A Wound Moisture and Assessment System includes a flexible coupon containing one or more electrochemical moisture sensors for measuring a moisture profile of a wound. The coupon is activated by a wireless RF scanner that provides power to the coupon for taking moisture measurements, receives the moisture measurements therefrom, and transmits the measurements to a computing device. The moisture measurements can be represented as a wound moisture map that allows a patient or caregiver to assess the health and healing progress of a wound such as an ulcer.
Claims19
