The wearable physiological monitoring system is a washable shirt, which uses an array of sensors connected to a central processing unit with firmware for continuously monitoring physiological signals. The data collected can be correlated to produce an overall picture of the wearer's health. In this paper, we discuss the wearable physiological monitoring system called 'Smart Vest'. The Smart Vest consists of a comfortable to wear vest with sensors integrated for monitoring physiological parameters, wearable data acquisition and processing hardware and remote monitoring station. The wearable data acquisition system is designed using microcontroller and interfaced with wireless communication and global positioning system (GPS) modules. The physiological signals monitored are electrocardiogram (ECG), photoplethysmogram (PPG), body temperature, blood pressure, galvanic skin response (GSR) and heart rate. The acquired physiological signals are sampled at 250samples/s, digitized at 12-bit resolution and transmitted wireless to a remote physiological monitoring station along with the geo-location of the wearer. The paper describes a prototype Smart Vest system used for remote monitoring of physiological parameters and the clinical validation of the data are also presented.
可穿戴生理监测系统是一件可清洗的衬衫，它使用一系列与带有固件的中央处理单元相连的传感器来持续监测生理信号。收集到的数据可以相互关联，以呈现穿戴者健康状况的全貌。在本文中，我们讨论了一种名为“智能背心”的可穿戴生理监测系统。智能背心由一件穿着舒适的背心组成，背心上集成了用于监测生理参数的传感器、可穿戴数据采集与处理硬件以及远程监测站。可穿戴数据采集系统采用微控制器设计，并与无线通信和全球定位系统（GPS）模块相连。所监测的生理信号包括心电图（ECG）、光电容积脉搏波描记图（PPG）、体温、血压、皮肤电反应（GSR）和心率。采集到的生理信号以250样本/秒的速率进行采样，以12位分辨率进行数字化处理，并与穿戴者的地理位置信息一起无线传输到远程生理监测站。本文描述了一个用于远程监测生理参数的智能背心系统原型，并给出了数据的临床验证情况。
