Development of Non-Restraint Vital-signals Detection System Using the Unique Electric-Conductable Fiber

Abstract

In this paper, we propose a sensor sheet in order to realize non-invasive and non-restrictive human vital-signals measurements. The proposed sensor is made of a kind of electric-conductive fiber, thus we can use it as a conventional bed spread. By making the sheet with the fiber in a matrix structure, we can detect the pressure distribution on it. This fact enables to acquire human vital signals such as breathing and heart beat. By a preliminary prototype, we show the basic properties of the proposed sensor.
