The entire construct is attached to a transparent medical tape to form a flexible bandage less than 3 mm thick. Non-healing chronic wounds are a significant medical problem."The smart bandage we created, with pH and temperature sensors and antibiotic drug delivery, is really a prototype for a wide range of possibilities," said Sonkusale. We are simply applying modern technology to an ancient art in the hopes of improving outcomes for an intractable problem," said Sonkusale.Inflammation could also be tracked not just by heat, but by specific biomarkers as well.  
A microprocessor reads the data from the sensors and can release drug on demand from its carriers by heating the gel."In fact, flexible electronics have made many wearable medical devices possible, but bandages have changed little since the beginnings of medicine.With the idea of providing an assist to the natural healing process, the researchers at Tufts University in the US designed the kinesiology tape bandages with heating elements and thermoresponsive drug carriers that can deliver tailored treatments in response to embedded pH and temperature sensors that track infection and inflammation.
The research is aimed at transforming bandaging from a traditionally passive treatment into a more active paradigm. Normal healing wounds fall within the range of pH 5.Non-healing chronic wounds are a significant medical problem. Chronic skin wounds from burns, diabetes, and other medical conditions can overwhelm the regenerative capabilities of the skin and often lead to persistent infections and amputations.5 to 6.The pH of a chronic wound is one of the key parameters for monitoring its progress
