Abstract

An electronic bandage includes (i) bandage material, (ii) a treatment portion supported by the bandage material, the treatment portion being constructed and arranged to provide a treatment, and (iii) a flexible electronic controller supported by the bandage material. The flexible electronic controller combines with the bandage material and the treatment portion to form a conformable bandage which conforms to a treatment surface. The flexible electronic controller is constructed and arranged to dynamically control application of the treatment to the treatment surface while the conformable bandage conforms to the treatment surface. Such a bandage is capable of being packaged as a unitary body which is small, inexpensive and/or disposable.
