Description:The following is a detailed description of embodiments of the disclosure depicted in the
accompanying drawings and the experimental methods. This invention introduces an
advanced smart bandage integrating PNIPAM hydrogel and IoT sensors for real-time
wound monitoring and enhanced healing. The invention addresses limitations in traditional
wound care through an innovative, scalable, and sustainable approach.
 Hydrogel Synthesis: The process begins with synthesizing Poly(N-isopropylacrylamide)
(PNIPAM) hydrogel. The hydrogel is prepared by dissolving the polymer in water, adding
crosslinkers, and initiating polymerization. This temperature-sensitive hydrogel is designed
to adapt to wound conditions by swelling and responding to environmental changes.
 Sensor Selection and Integration: Biocompatible sensors capable of measuring temperature,
moisture, and pH are embedded into the hydrogel. The sensors are designed to be flexible
and functional without compromising the hydrogel's properties, ensuring comfort and
efficiency.
 Wireless Communication Module: A wireless data transmission system is developed to send
real-time information collected by the sensors to healthcare providers. A user-friendly
interface, such as a mobile app or web dashboard, enables remote monitoring of wound
conditions.
 Smart Bandage Assembly: The hydrogel and sensors are integrated into a bandage format,
incorporating a flexible substrate for ease of application. The assembly ensures the bandage
is lightweight, comfortable, and suitable for prolonged wear.
 In Vitro Testing: Laboratory testing evaluates the swelling behavior, thermal
responsiveness, and biocompatibility of the hydrogel, as well as the accuracy and durability
of the sensors. The results validate the bandage's performance under simulated wound
conditions.
 In Vivo Testing: The smart bandage is tested on animal models to assess its performance in
real-world wound care scenarios. The testing follows ethical guidelines and evaluates
healing rates, sensor reliability, and user comfort.
 Design Optimization: Based on testing outcomes, the design is refined to enhance sensor
placement, communication efficiency, and overall usability. Adjustments are made to
improve performance, scalability, and cost-effectiveness.
 Scalability and Clinical Integration: The invention is designed to integrate seamlessly into
healthcare systems, offering applications in both urban and rural settings. The scalable
design reduces the need for frequent hospital visits, improves patient outcomes, and
supports sustainable medical practices.
