Selection of transducer material for use with 'optical' foot pressure systems.
'Optical' foot pressure systems, or pedabarographs, use a white plastic or rubber material as the transducer. In the past, materials have been used which are not appropriate for calibrated measurements, particularly in dynamic studies (i.e. walking measurements). We describe a simple method for selecting transducer materials and make comparisons between commonly used materials.
