Compression therapy is mainly applied for the treatment of chronic venous disorders such as leg ulcers and oedema. During compression therapy, a specific pressure profile in the range of 35 mmHg to 45 mmHg was applied on the wounded area for the treatment to be effective. The ideal characteristics for a pressure sensor in monitoring sub-bandage pressure should be flexible, durable and reliable to ensure ease of use and comfort for the patient. Plastic optical fibres (POF) are extremely flexible and have high tensile strength, making them a suitable candidate to be embedded into the textile. In this research, POF integrated with a flexible tube has been investigated as a pressure sensor to monitor sub-bandage pressure. The main components of this system were POF, flexible tube, LED transmitter, photodiode circuit, amplifier circuits, and NodeMcu ESP8266 wifi module. The 660 nm red LED is used as a light source to illuminate the flexible tube. The pressure that is applied to the flexible tube will change the reflected light and this response will be detected by the photodiode via POF. The amplifier circuit LM358 is used to amplify the voltage signal and the NodeMcu ESP8266 Wi-Fi module is used to send the data to the Blynk app on the smartphone. Through the Internet of Things (IoT) platform, the sub-bandage pressure can be monitored and assessed online by the medical practitioner and this system can be used as a tool in compression therapy management.
