Abstract

This paper proposes a new visualizing method for analyzing a pulse caused by a heart beat signal from a car seat. The pulse signal is measured by piezoelectric sensors in the seat, in order to analyze characteristic frequency of the pulse with wavelet transform. It is needed a method for visualization of these signals based on the wavelet transform although there are 18 channels with different delays and measured signals are contaminated by noise. An experiment result shows effectiveness of the proposing method.
