Abstract

There are many factors that may have a significant effect on the skin wound healing process. The environment is one of them. Although different previous research woks have highlighted the role of environmental elements such as humidity, temperature, dust, etc., in the process of skin wound healing, there is no predefined method available to identify the favourable or adverse environment conditions that seriously affect (positively or negatively) the skin wound healing process. In the current research work, an IoT-based approach is used to design an AQSS (Air Quality Sensing System) using sensors for the acquisition of real-time environment data, and the SVM (Support Vector Machine) classifier is applied to classify environments into one of the two categories, i.e., “favourable”, and “unfavourable”. The proposed system is also supported with an Android application to provide an easy-to-use interface. The proposed system provides an easy and simple means for patients to evaluate the environmental parameters and monitor their effects in the process of open skin wound healing.

Summary

Introduction

Skin makes up 15% of the human body’s weight and is considered as the most essential part of the human body. Skin acts as safeguard for all body components, as all body parts are beneath it, so any injury to the human body may first affect skin. Any injury to skin results in skin wounds. Skin wounds vary in size and type, which depends on the intensity and type of injury. Skin wounds are divided into two major categories, i.e., open wounds and closed wounds. Tissues beneath the skin layer are not affected by injury; only the external skin layer is affected; while in open wounds, skin is affected by injuries such that tissues beneath the skin layer become visible and exposed to the outside atmosphere. Open wounds further are divided into four major types: abrasions, avulsions, lacerations and punctures
