Abstract
  • Moisture and pH content in a wound have exhibited to play a significant role in determining the degree and rate of healing of the wound. This enhances wound care by helping the clinicians make treatment decisions and ultimately towards a targeted therapeutic approach to wound management. A recent breakthrough in this area of healthcare is development of a moisture sensor that measures the moisture content in a wound at different stages during the healing process. The moisture sensor works on the principle of measuring the impedance levels from the exudate which indicates the condition of the wound as being wet, moist, dry etc. This moisture sensor utilizes AC voltages to give the moisture readings. Another significant sensor has been designed that would measure the pH of the wound. This sensor along with the moisture sensor would provide the content of the two significant parameters that determine the wound conditions as mentioned earlier. The pH sensor is a potentiometric sensor and it might lose its voltage stability due to influence of AC voltages when measuring moisture content in the wound. The main task of the project is to study the behavior and stability of the pH sensor upon application of AC voltages. This study would determine the efficiency of the pH sensor upon integrating with the moisture sensor and if successful, the combination of both the sensors would greatly enhance the area of wound management. The results obtained from this project provide essential data to proceed with the integration of the two sensors or not.
