Measurements of pressure, temperature and humidity at the subject/cushion interface

Pressures at the user-seat interface of a wheelchair will be measured by non-invasive method using a pressure pad positioned directly on the cushion, under the seated subject. No contact with the skin will take place

Temperatures at the ischial tuberosities will be measured by a non-intrusive methods using sensors taped directly on the pants of the participants. No contact with the skin of the participants will take place
