Abstract
In recent years, studies on posture analysis have been actively conducted in order to solve health problems related to posture. In this paper, we propose a net-type pressure sensor array using wires. The pressure distribution is estimated by the wire tension with pulleys and force sensors. By adopting a matrix-like structure, it is possible to configure with fewer sensors than the resolution of the pressure distribution. Furthermore, the “Center Of Pressure: COP” position, which is closely related to the posture, can be estimated by measuring each wire matrix. In this paper, the estimation accuracy of COP is verified by experiments and the estimation accuracy is improved by using Gaussian filter.
