Abstract
This paper presents a wearable system to detect the pressure and heat in a compressive orthotic and trigger an alarm when the values are beyond the standard margin of safety. In this way, the foot ulcers on diabetes' patients could be controlled and prevented. Arduino Nano is used as a microcontroller, two force sensors FSR402 and four temperature sensors LM35DZ are controlled by the microcontroller to detect the pressure and heat at different positions inside the compressive orthotic. Accuracy of the temperature sensor is ±0.25 °C. A pair of Bluetooth HC-06 is used to send data to computer. The threshold value of pressure and temperature difference is 3.38 N and 2.2 °C respectively. An alarm and warning LED will be triggered on the user interface based on LabVIEW. All the components are set on a printed circuit board and all the sensors are fixed on the inside of compressive orthotic as a wearable device.
