Development of Radio-Frequency Front-End of Wireless Personal Health Record (pHR) Cards

位于安大略省惠特比的Kela Medical Inc.是一家名为PHR(Personal Health Record)的电子个人健康卡的领先开发商，它为医生和患者创建、访问和维护电子医疗记录提供了经济实惠的解决方案。PHR卡是一种普通信用卡大小的便携式媒体记录产品，带有内置微芯片，以加密形式存储患者的整个医疗记录，包括医疗检查、先前存在的血液检查和诊断成像。该卡可以连接到任何计算机，而不需要特殊软件，因此医疗从业者可以毫不费力地访问记录。这是第一个具有管理医疗报告能力的智能卡系统。Kela Medical决心开发无线Phr卡，以进一步提高其现有Phr卡的效率并降低成本。无线PHR卡将包含一个内置的无源无线微芯片，该芯片从读卡器发射的无线电波中获取运行功率，存储患者的医疗记录，并通过近场无线通道与读卡器通信。Kela Medical正在与瑞尔森大学的研究人员合作，开发无线PhR卡的射频前端。本项目的目标是开发无线相控卡的射频前端。前端将从阅读器发射的射频波中获取电能，对接收的信号进行放大和解调，对恢复的数据进行解码和解密，将恢复的数据存储在电子可擦除可编程只读存储器中，对存储的数据进行编码和调制，并使用反向散射将数据上传到阅读器。

Kela Medical Inc. Whitby, Ontario, is a leading developer of electronic personal health cards called pHR (Personal Health Record) cards that provide economical solutions for physicians and patients to create, access, and maintain electronic medical records. The pHR card is a portable media record product of the size of an average credit card with a built-in microchip that stores a patient's entire medical record including medical tests, pre-existing blood work and diagnostic imaging in an encrypted form. The card can be connected to any computer with no special software required so that healthcare practitioners can access the records without difficulty. It is the first smartcard system of its kind with the capacity to manage medical reports. Kela Medical is determined to develop wireless pHR cards to further improve the efficiency and reduce to cost of its existing pHR cards. The wireless pHR cards will contain a built-in passive wireless microchip that harvests the operational power from radio-frequency waves emitted from the readers of the cards, stores a patient's medical record, and communicates with the readers via near-field wireless channels. Kela Medical is working with researchers of Ryerson University to develop the radio-frequency front-end for wireless pHR cards. The objective of this project is to develop the RF front-end of wireless pHR cards. The front-end will harvest power from RF waves emitted from readers, amplify and demodulate received signals, decode and de-encrypt recovered data, store recovered data in an electronically erasable programmable ready-only memory, encode and modulate stored data, and upload data to the reader using back-scattering.
