Summary
This study introduces a smart bandage with Near-Field Communication (NFC) technology to monitor compression therapy pressure and wound healing. The battery-free device accurately measures pressure and detects wound fluid, improving patient care.
Area of Science:
- Biomedical Engineering
- Wearable Technology
- Medical Device Innovation
Background:
- Compression therapy is vital for wound healing but lacks precise pressure monitoring.
- Current methods for assessing wound conditions and applied pressure are often indirect or cumbersome.
Purpose of the Study:
- To develop an intelligent, battery-free bandage system for simultaneous monitoring of compression pressure and wound exudate levels.
- To leverage Near-Field Communication (NFC) technology for wireless data acquisition and power harvesting in wound care.
Main Methods:
- Integration of a force-sensitive resistive sensor for pressure measurement and a capacitive sensor for exudate detection.
- Utilizing NFC for wireless power transfer and data communication with a mobile device reader.
- Employing a microcontroller to process sensor data via analog-to-digital conversion.
Main Results:
- The smart bandage successfully measured pressures up to 140 mmHg.
- Exudate detection capabilities were demonstrated for volumes up to 200 μL.
- Wireless, battery-free operation via NFC was confirmed as feasible.
Conclusions:
- The proposed NFC smart bandage offers a viable solution for real-time, non-invasive monitoring of compression therapy and wound status.
- This technology has the potential to enhance therapeutic efficacy and patient comfort in wound management.
