A team of researchers led by scientists at Tufts University has developed a prototype bandage that can actively monitor chronic wounds, and deliver appropriate drug treatments to improve the chances of healing.
The smart bandages include pH and temperature sensors, as well as flexible sensors to monitor oxygenation, a measure of healing.
A microprocessor reads data from the sensors and can release drugs on demand from its carriers by heating a gel within the bandage.
The entire system is attached to a transparent medical tape to form a flexible bandage less than three millimeters thick.
"One can imagine embedding other sensing components, drugs, and growth factors that treat different conditions in response to different healing markers," says Tufts' Sameer Sonkusale.
