The need of medicine for portable electronic equipments smallers [sic], reliables [sic] and inexpensive supports the development of biotelemetry techniques passive monitoring in invasive biomedical applications. In this work are presents [sic] the development and testing of a passive biotelemetry sensor device, which uses the technology of Radio Frequency Identification - RFID. The developed device, commonly referred to as the tag, is basically composed of three parts: the RFID architecture used for low frequency, the control unit responsible for data processing and sensor unit responsible for monitoring blood pressure. As the tag is passive i.e. does not contain batteries to activate it, It [sic] is necessary a device that makes its energizing and also decode the data transmitted by it. This device that reads and sends a signal to activate the transponder is commonly called a reader. The reader used in this project will have its firmware adapted to handle the pressure value sent by the tag. This work also presents theoretical modeling of the system and the specification of components for practicing the validation tests. In theoretical modeling are presented mathematical models of system behavior. The results validate the methodology used for the development of passive RFID sensor that aims to measure blood pressure.
