Hypertension, a silent killer, is the biggest challenge of the 21 century in public health agencies worldwide [1]. World Health Organization (WHO) statistic shows that the mortality rate of hypertension is 9.4 million per year and causes 55.3% of total deaths in cardiovascular (CV) patients [2]. Early detection and prevention of hypertension can significantly reduce the CV mortality. We are presenting a wireless chest wearable vital sign monitoring platform. It measures Electrocardiogram (ECG), Photoplethsmogram (PPG) and Ballistocardiogram (BCG) signals and sends data over Bluetooth low energy (BLE) to mobile phone-acts as a gateway. A custom android application relays the data to thingspeak server where MATLAB based offline analysis estimates the blood pressure. A server reacts on the health of subject to friends & family on the social media - twitter. The chest provides a natural position for the sensor to capture legitimate signals for hypertension condition. We have done a clinical technical evaluation of prototypes on 11 normotensive subjects, 9 males 2 females.
高血压，这个无声的杀手，是21世纪全球公共卫生机构面临的最大挑战[1]。世界卫生组织（WHO）的统计数据显示，高血压的年死亡率为940万，占心血管（CV）疾病患者总死亡人数的55.3%[2]。早期发现和预防高血压可显著降低心血管疾病死亡率。我们正在展示一个无线胸部可穿戴生命体征监测平台。它可测量心电图（ECG）、光电容积脉搏波描记图（PPG）和心冲击图（BCG）信号，并通过低功耗蓝牙（BLE）将数据发送到充当网关的手机。一个定制的安卓应用程序将数据中继到物联网服务器，基于MATLAB的离线分析在该服务器上估计血压。一台服务器会在社交媒体——推特上，就受试者的健康状况向其朋友和家人做出反馈。胸部为传感器提供了一个自然的位置，以便捕捉用于高血压状况的有效信号。我们已对11名血压正常的受试者（9名男性，2名女性）的原型进行了临床技术评估。
