具生理訊號感測之智慧床墊設計

https://v.youku.com/v_show/id_XMzY4NTIwNDIwOA==.html?spm=a2h3j.8428770.3416059.1

Introduction

本作品只需放置於床墊中,運用壓電感測、壓力感測與演算法的分析,可實行不用直接接觸皮膚,並對心率、呼吸及體動進行即時監測,利用心率改變及身體動作,進而分析睡眠狀態。

使用壓電感測器感測身體訊號,再經由硬體濾波得到呼吸及脈搏訊號

使用 ADC converter 收入感測訊號,再經由 ARC EMSK 運算後輸出心率及呼吸頻率

I/O

PMOD1 => UART 38400bps 輸出 心率,呼吸,呼吸訊號,脈搏訊號

PMOD2 => I2C ad7991 ADC模組 reference為板子的3.3V 使用 channel 1 作為壓電感測輸入
