The technology merges flexible, biocompatible materials with machine learning algorithms capable of interpreting live data streams from the wound site. These intelligent systems move wound care beyond passive protection, enabling clinicians to make earlier, more informed treatment decisions.
From Passive Protection to Predictive Systems
Chronic wounds such as diabetic foot ulcers and pressure sores often stall due to complex and shifting local conditions like infection, inflammation, and glucose imbalance. Traditional dressings provide coverage but no information about what’s happening inside the wound. Even modern hydrogels, while helpful in maintaining moisture, cannot track changes in healing or detect complications early.
The systems outlined in the review are designed to fill this gap. By embedding sensors directly into the dressing and pairing them with AI, clinicians gain access to continuous physiological data and predictive insight—transforming how wounds are monitored and managed.
Data Collection Starts at the Wound Site
At the core of these smart dressings is a conductive hydrogel that mimics the body’s natural transepithelial potential, supporting healing by encouraging cell migration and reducing inflammation. But unlike conventional materials, these hydrogels also contain sensors that detect real-time shifts in pH, temperature, glucose, and pressure—key indicators of wound status.
As the wound environment changes, the embedded electronics convert biochemical fluctuations into electrical signals. These are transmitted wirelessly for processing, eliminating the need for invasive checks or dressing removal.
The critical innovation lies not in sensing alone, but in how the data is interpreted. Machine learning algorithms, including K-nearest neighbors (KNN), artificial neural networks (ANN), and convolutional neural networks (CNN), analyze the continuous data stream to classify the wound’s condition and predict how it will progress.
AI enables pattern recognition that goes beyond what any clinician could infer through observation alone. It can distinguish between normal fluctuations and early signs of infection or delayed healing, flagging risks before they escalate. The system effectively acts as a predictive assistant, offering real-time guidance that adapts care to the wound’s specific and changing needs.
According to the authors, this AI layer transforms the dressing from a smart material into a closed-loop feedback system, one capable of both sensing and responding in a clinically meaningful way.
Material Strategies for Intelligent Systems
Building such a system requires materials that can simultaneously support healing and house stable electronics. The review outlines two main approaches: inorganic nanomaterials like carbon nanotubes, graphene, and MXenes, known for their conductivity and sensitivity but limited by dispersion and biocompatibility; and conductive polymers such as polypyrrole (PPy) and PEDOT, which are easier to integrate biologically but may degrade or lack mechanical resilience.
To address these limitations, the team is working to develop hybrid composites that combine the strengths of both categories. These allow for long-term signal stability, structural flexibility, and safe integration with the wound environment.
Clinical Use Cases: Data in Action
Applications for AI-integrated dressings are already emerging. In pressure ulcers, they help prevent tissue damage by continuously tracking load and temperature. For diabetic wounds, they monitor local glucose levels and oxidative stress to manage metabolic factors that affect healing. On joints or high-movement areas, the dressings flex with the body while still collecting reliable diagnostic data.
Importantly, current prototypes often focus on one or two biomarkers and require external AI processing. But the review points to ongoing work in embedding multi-sensor arrays and lightweight, onboard AI chips, bringing wound analysis directly into the dressing itself.
This will be essential for scaling the technology to home care, low-resource settings, and long-term management of complex wounds.
A Shift in the Role of the Dressing—and the Clinician
The integration of AI at the dressing level represents a fundamental change in how wound care is delivered. Instead of episodic checks and static treatments, care becomes continuous, predictive, and personalized, responding to the wound’s needs in real time.
As such, the dressing becomes more than a protective barrier; it becomes an “intelligent interface” between the wound and the clinician. The AI doesn't replace expertise, but enhances it, offering data-driven support to improve timing, accuracy, and outcomes.
While the potential is significant, several challenges do remain. Material stability, long-term biocompatibility, and the clinical validation of AI models must be addressed before widespread adoption is feasible. Integration into existing healthcare infrastructure, especially electronic records and remote monitoring platforms, will also be essential.
Still, wound care is moving toward intelligence at the source. As sensor quality improves and AI models become more accurate, these dressings could reshape how chronic wounds are monitored and treated, turning reactive care into proactive recovery.
