SBIR Phase I: Radio Frequency Identification (RFID) Patient Monitoring System with Microelectromechanical Systems (MEMS) Cardio Sensor

这个小型企业创新研究(SBIR)第一阶段项目旨在开发基于心音MEMS技术的无线无电池RFID心脏监测系统。该系统使用一次性MEMS传感器，其形式为粘性标签，可通过远程射频源远程接收电力。在该系统中，通过与个人计算机(PC)节点进行无线通信来获得心音。通过PC，心音以图形方式呈现、记录或分析，以供进一步使用。PC节点可以是远程患者监护(RPM)系统的一部分。与其他心电图仪系统相比，无线心电图仪还有其他一些优势：与多线心电、多通道心血管系统监测相比，人体和传感器之间没有电线连接，也没有电接触点。带有一次性标签传感器的商业化产品可以取代目前全球数百万人使用的布线和/或电池供电的心脏监测设备。该系统具有低成本和高通用性的系统平台，将首先在非临床环境中获得资格，然后在医院内部广泛使用。

This Small Business Innovation Research (SBIR) Phase I project aims to develop a wireless and batteryless RFID heart monitoring system based on phonocardiograph MEMS technology. The system uses a disposable MEMS sensor in the form of adhesive tags that receive power remotely through a remote radio frequencysource. In this proposed system, heart sound is obtained through wireless communication with a personal computer (PC) node. With the PC, heart sound is presented graphically, recorded or analyzed for further use. The PC node can be part of a remote patient monitoring (RPM) system. The wireless phonocardiograph offers some other advantages over other cardiograph systems: no wire connections and no electrical contact point between the human body and the sensor as compared with a multi-wire ECG, multi-channel monitoring of the cardiovascular system.The commercialized product with disposable tag-based sensors can replace the jungle of wiring and/or battery powered heart monitoring devices currently in use by the millions worldwide. This system with low cost and a highly versatile system platform will be qualified first with non-clinical setting and later for extensive use within the hospital itself.
