Abstract
The study presented here aims at developing a PVDF sensor that can be inserted within a seat-cover fabric. The final objective is to measure accurately the mass of a passenger sitting in a car. The measurement method consists in analyzing the response under compressive stress of a PVDF disc using the resonant frequency of the material. The maximal phase of the sensor at resonant frequency is taken up for each constraint applied. The influence of external parameters (vibrations, temperature variations) has been studied. The position of the sensor in the seat-cover was given starting from an ergonomic study. Tests in real case were carried out. A linear variation of the phase has been shown only taking into account the mass of the subjects’ sitting position.
