A Study on New Triage Assisting Device Utilizing the Pyroelectric Effect in the Piezoelectric Device

Abstract

In this paper, we describe a new type method to develop a new triage assisting device. We employ a piezoelectric element used for a buzzer. The pyroelectrics phenomenon of the device was applied to detect the respiration as a sensor and original buzzer function was used to generate alert sound signal as a actuator as well the respiration condition was optically shown by using high emission LED. We realized a triage assisting device based on a microprocessor and confirmed the validity. The device detects respiration with high S/N ratio and optically shows the respiration condition as well it generates alert sound signal when the respiration are abnormal condition.
