Development of Respiratory Signal Detection System Based on Intelligent Terminal Ultrasonic Transceiver

Jingwen Qu

Abstract


Breathing is one of the important vital signs with periodic characteristics. Its small amplitude of movement and weak reflected energy make non-contact breathing monitoring challenging. This innovative project focuses on developing a respiratory signal detection system based on intelligent terminal ultrasound transceiver. Generate and receive Frequency Modulated Con-tinuous Wave (FMCW) sound signals using smartphones, computers, and even external hardware. Complete the extraction and analysis of respiratory signals to pave the way for further health monitoring.

Keywords
