Measurement of Multiphysical Fields at the Subject-sitting Interface

Measurement of Multiphysical Fields at the Subject-sitting Interface

With the population ageing and the increase in disabilities prevalence, demand for wheelchairs is increasing. Padding and shape of seat are important factors for comfort when sitting for long periods of time. Sustained mechanical loads induced by the seated stance can cause pressure ulcers in the ischial prominences. Temperature and humidity have also been shown to be important in the development of pressure ulcers.

The aim of this research is to measure the pressure, temperature and relative humidity fields at the user-seat interface of a wheelchair.
