Wheelchair Pressure Distribution Mapping System Application

Description
One risk faced by wheelchair–bound patients is the development of pressure ulcers, which reduce the patient’s quality of life and increase the risk of infection. This can lead to major complications. This project is designed to reduce this risk by constructing a pressure sensor array and application to enable visualization of high–pressure areas that may form pressure ulcers.
There are several devices that can measure the pressure distribution on a wheel chair, but they are expensive and may be inaccessible. The application interfaces with the pressure sensor array via Bluetooth and then displays this information as a heatmap and allows users to calibrate the sensitivity of the pressure pad.
