Infrared sensor system using the pyroelectricity of PVDF has been proposed as walking support device which supports the walking of the visually handicapped. And, the basic configuration of infrared sensor in this sensor system has been discussed on the basis of basic response of PVDF film, and the sensor system which consists of the infrared sensor unit and electronic circuit including the V-F converter has been designed. By these experiments, it was realized the infrared sensor system which clearly detects a crossing man at 5m distance.
