Abstract – Chronic wound management requires continuous monitoring to ensure timely healing and prevent infection; however, conventional methods rely on periodic dressing changes at intervals of 2472 hours, leading to gaps in monitoring. During these intervals, infection-related physiological changes may occur within 624 hours, resulting in delayed diagnosis, complications, and extended recovery time. To overcome these limitations, this work presents the design and development of a low-cost, reusable, and wearable wound monitoring system intended for home and rural healthcare applications.The proposed system integrates multiple flexible sensors to continuously measure key wound parameters, including temperature, humidity, pH, oxygen level, and pressure, which are critical indicators of wound condition and healing progression. The system is built around an ESP32-C3 microcontroller with Bluetooth Low Energy capability, enabling real-time transmission of sensor data to a mobile application for remote monitoring and timely- intervention.An embedded Artificial Intelligence model based on Decision Tree logic is implemented to analyze sensor data and classify wound conditions into healing, stable, and worsening states. Furthermore, a closed-loop drug delivery mechanism is incorporated, where a micro peristaltic pump is activated to administer a controlled dosage of medication when abnormal conditions are detected. This transforms the system into an intelligent therapeutic platform. The proposed wearable system bridges the gap between clinical visits by enabling continuous monitoring, early detection of infection, and real-time alerts. It enhances patient safety, reduces healthcare burden, and improves wound management outcomes, offering a scalable and user-friendly solution for advanced wound care applications.

- INTRODUCTION
Chronic wounds, such as diabetic ulcers, pressure sores, and burn injuries, represent a significant challenge in modern healthcare due to their prolonged healing time and high risk of infection. Effective wound management requires continuous monitoring of physiological parameters to ensure proper healing and prevent complications. However, conventional wound care practices rely on periodic inspection and dressing changes at intervals of 2472 hours. This creates a critical monitoring gap, as infection-related physiological changes can occur within 624 hours, often leading to delayed diagnosis, increased risk of complications, extended hospitalization, and higher treatment costs.
In addition, traditional wound dressings lack real-time feedback mechanisms, embedded intelligence, and early warning systems, making them inadequate for proactive wound management. This
limitation is particularly significant in home-based and rural healthcare settings, where access to medical professionals is limited.
- Need for Smart Wound Monitoring
With advancements in wearable technology, Internet of Things (IoT), and embedded systems, there is an increasing demand for intelligent healthcare solutions that enable continuous and real-time monitoring. Smart wound monitoring systems can overcome the limitations of conventional methods by providing continuous data acquisition, early detection of abnormalities, and timely intervention.
The integration of multiple physiological parameters such as temperature, humidity, pH, oxygen level, and pressure offers a comprehensive understanding of wound conditions. Such systems can significantly improve patient outcomes by enabling proactive and personalized wound care management.
- Proposed System Overview
To address these challenges, this work proposes a smart wearable wound monitoring system that integrates multiple sensors to measure key wound parameters. The system is built around an ESP32-C3 microcontroller with Bluetooth Low Energy (BLE) capability, enabling real-time transmission of sensor data to a mobile application for remote monitoring.
An embedded Artificial Intelligence (AI) model based on Decision Tree logic is implemented to analyze sensor data and classify wound conditions into healing, stable, and worsening states. Furthermore, a closed-loop drug delivery mechanism is incorporated, where a micro peristaltic pump delivers a controlled dose of medication when abnormal conditions are detected. This approach transforms the system into an intelligent and automated wound care platform.
- Nature of the Research and Problem Statement
The nature of this research is interdisciplinary and application- oriented, combining biomedical engineering, embedded systems, IoT, and artificial intelligence to develop a prototype-based wearable healthcare solution. The system involves both hardware and software components, including sensor integration, embedded processing, wireless communication, and AI-based analysis.
Chronic wound management remains a major healthcare concern due to the lack of continuous monitoring and timely detection of infection. Existing systems are often expensive, complex, and lack real-time intelligence and automated response mechanisms. Therefore, there is a need for a cost-effective, portable, and intelligent system that integrates multi-sensor monitoring, embedded AI, wireless communication, and automated drug delivery to improve wound care management.

- LITERATURE REVIEW
Recent advancements in chronic wound management have focused on improving early detection of infection and enhancing healing outcomes through technological interventions. Traditional wound care methods primarily rely on periodic inspection and dressing changes, which often fail to provide continuous monitoring and timely identification of complications.
Several studies have explored the use of biosensors to monitor key wound parameters such as temperature, pH, and oxygen levels. These parameters serve as important indicators of infection and tissue condition. However, most existing systems are limited to single-parameter monitoring and do not provide a comprehensive assessment of wound health.With the development of wearable technology and Internet of Things (IoT), smart wound monitoring systems have emerged that enable real-time data collection and remote monitoring. These systems reduce the need for frequent hospital visits and support timely intervention. Despite these advantages, many existing solutions are complex, expensive, and lack embedded intelligence for autonomous decision-making.
Recent research has also incorporated Artificial Intelligence (AI) techniques for wound classification and prediction. Machine learning models can improve diagnostic accuracy but often require high computational resources and cloud-based processing, making them less suitable for real-time embedded applications.To overcome these limitations, there is a need for a low-cost, wearable system that integrates multi-sensor monitoring, embeddd AI, and automated therapeutic response. The proposed system addresses these challenges by combining real-time sensing, intelligent analysis, and closed-loop drug delivery into a single platform, making it suitable for practical healthcare applications.
- Overview of Literature
Chronic wound management has received considerable attention in recent years due to the increasing prevalence of diabetes, vascular disorders, and age-related complications. Various approaches, including advanced wound dressings, smart materials, biosensors, and wearable monitoring systems, have been explored to enhance healing outcomes and reduce infection risks. Studies emphasize the importance of monitoring physiological parameters such as temperature, pH, and oxygen levels, as these indicators provide early signs of infection and tissue deterioration.
Hydrogel-based dressings and regenerative materials have been widely investigated for their ability to maintain a moist wound environment and promote tissue regeneration. However, these solutions are primarily passive and lack real-time monitoring and decision-making capabilities. Similarly, biosensor-based techniques, including electrochemical, optical, and colorimetric sensors, enable detection of wound changes but are often limited to single-parameter monitoring.
With advancements in wearable technology and Internet of Things (IoT), smart wound monitoring systems have emerged, enabling continuous data acquisition and remote monitoring. Despite these developments, many existing systems are
expensive, complex, and unsuitable for long-term use in home or rural settings. Furthermore, most solutions lack embedded intelligence and automated therapeutic response, highlighting the need for an integrated and intelligent wound monitoring system.
- Review of Smart Wound Monitoring System
Significant advancements have been made in smart wound monitoring technologies, focusing on improving sensing accuracy, wireless connectivity, and patient comfort. Early systems utilized temperature and pH sensors as primary indicators of infection and inflammation. While these systems provided useful preliminary insights, they lacked comprehensive monitoring due to the absence of additional parameters such as humidity, oxygen level, and pressure.The introduction of IoT-based systems enabled real-time data transmission through wireless protocols such as Wi-Fi and Bluetooth, facilitating remote monitoring and reducing hospital visits. However, challenges such as high power consumption, limited battery life, sensor drift, and dependence on external processing limited their effectiveness.
Recent developments have focused on multi-sensor integration combined with artificial intelligence (AI) techniques to enhance diagnostic accuracy. These systems utilize multiple parameters to classify wound conditions and support data- driven decision-making. However, many of these approaches rely on computationally intensive models, making real-time embedded implementation challenging.The development of flexible and wearable electronic platforms, including flexible printed circuit boards (FPCBs), has improved device comfort and usability. Despite these advancements, most existing systems are limited to monitoring and lack automated therapeutic capabilities.To address these limitations, recent research trends emphasize closed-loop therapeutic systems that integrate monitoring with automated intervention. The proposed system builds upon these advancements by combining multi-sensor monitoring, embedded AI, wireless communication, and automated drug delivery into a single wearable platform.
- AI and Rule-Based Techniques in Wound Monitoring
Artificial Intelligence (AI) has emerged as a key enabler in modern healthcare, facilitating advanced data analysis, pattern recognition, and predictive decision-making. In wound monitoring applications, AI techniques are used to analyze physiological data and detect early signs of infection or delayed healing.Machine learning algorithms such as Random Forest, Support Vector Machines (SVM), and Artificial Neural Networks (ANN) have been widely applied for wound classification. These models can identify complex relationships between parameters and provide high accuracy. However, they require large datasets, high computational power, and cloud- based processing, limiting their suitability for real-time embedded systems.To overcome these limitations, lightweight AI approaches such as rule-based systems and Decision Tree algorithms are increasingly used in wearable healthcare devices. These methods rely on predefined threshold values and structured decision rules, enabling fast, interpretable, and low-power operation.Decision Tree models are particularly
suitable for embedded systems due to their low computational complexity and ease of implementation. They allow simultaneous evaluation of multiple parameters and provide clear decision pathways, making them appropriate for medical applications.
The proposed system adopts a Decision Tree-based embedded AI model to classify wound conditions into healing, stable, and worsening states. A key innovation is the integration of a closed-loop drug delivery mechanism, where the system automatically delivers medication based on detected conditions. This approach enables real-time monitoring, intelligent decision-making, and automated intervention, making the system suitable for practical healthcare applications
