It was reported by the International Society for Pharmacoeconomics and Outcomes Research that chronic wounds account for $28 to $32 billion of US Medicare healthcare expenditures. The high cost can be attributed to several factors such as costs associated with multiple doctor visits and bacterial infection prevention. Smart bandages have been developed to lower wound care costs by wirelessly monitoring and preventing wound infection. Unfortunately, conventional smart bandages are expensive, uncomfortable, and do not promote healing. Moreover, these bandages require trained personnel to apply and interpret the results from smart bandages. Therefore, there is a need for smart bandages that are patient-friendly and promote wound healing.

Researchers at Purdue University have developed a smart bandage, OPSB, that can assess tissue damage in open and closed wounds, promote healing through its breathable design, and doesn't require medical personnel for application. OPSB real-time monitors uric acid and pH at the wound site and wirelessly communicates this information to physicians; thereby, reducing the number of visits to the doctor. OPSB can also detect and monitor pressure ulcers.
