What if your bandage could tell you when it's infected? That's the promise of smart wound dressings. The antimicrobial wound care dressing market forecast predicts that smart dressings will be a major growth area, integrating sensors for pH, temperature, and bacterial load. Why? Because removing a dressing to check the wound disrupts healing and risks infection.

What's already available? Colour‑changing indicators — some dressings turn purple when infection is present (based on pH or bacterial enzymes). The antimicrobial wound care dressing market analysis notes that the fastest‑growing mechanism of action is moisture management, because even without infection, improper moisture delays healing.

In development: dressings that release antibiotics on demand (triggered by bacterial toxins), and dressings with Bluetooth that send data to your phone. But cost and regulatory approval are hurdles.

The takeaway: smart dressings are coming, but they're not mainstream yet. For now, trust your eyes and nose. If a wound smells foul, looks red, or feels hot, see a doctor. Don't wait for a sensor.
