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.
