According to a recent article in the journal Small, researchers led by Pooria Mostafalu sought to increase the healing rate of chronic wounds by creating a smart bandage. “The wound environment is dynamic, but their healing rate can be enhanced by administration of therapies at the right time,” the article says.

The smart bandage can monitor both temperature and pH of the wound. If it detects a change, it can diagnose the problem and dispense drugs as necessary, thanks to a central processor, which a doctor can program to administer treatment if certain conditions are detected. “A stimuli‐responsive drug releasing system comprising of a hydrogel loaded with thermo‐responsive drug carriers and an electronically controlled flexible heater is also integrated into the wound dressing to release the drugs on‐demand,” the paper says. The bandage will also monitor treatment to determine if further steps are necessary. It can also provide real-time status updates via Bluetooth.
