Application for medicine and healthcare using a technology of body shape estimation

Abstract

A body shape estimation belt had been developed. The belt was designed for EIT and shape measurement simply. Sixteen channels of curvature sensors and wirings had been integrated into a thin flexible circuit board. The size of the belt was 935 * 58 * 0.34 mm. Total length and weight included measurement circuit was 1,005 mm and approx. 200g respectively. The system could estimate a shape at 50 frames/s in real-time. A basic performance was evaluated by estimating shapes of subset ')' and number '6' in real-time. Curvature sensors showed linear correlation with high correlation coefficient as R=0.998 at maximum. And shapes of subset ')' and number '6' had been estimated well. These results showed that the developed shape estimation belt had a basic performance and feasible for many clinical and healthcare applications.
