Flexible Ultrasonic Patch for Accelerating Chronic Wound Healing

Ultrasound treatment is an effective method for accelerating chronic wound healing. However, it is not widely used because traditional ultrasonic probes cannot be conformal to the wound surface, which leads to limitations of use and unstable treatment effects. In addition, the use of liquid coupling agent increases the chance of wound infection. A strategy is proposed to design and fabricate a flexible ultrasonic patch for treating chronic...
