Abstract
In this study, we fabricated a triaxial force sensor for prevention of pressure ulcers by plaster casts. The size of the triaxial force sensor is 16×25×8 mm^3. We put this sensor into the plaster casts, and measure the contact force between the heel and the plaster casts. We measured the total force by adding X, Y, and Z axis force under the conditions of the heel height from 50 mm to 200 mm and the knee bending angle from 0 degree to 50 degree. We confirm that the minimum total force was 110 kPa at heel height of 50 mm and the knee bending angle of 20 degree.
