This work deals with the development and characterization of a potentially implantable\nblood pressure telemetry system, based on an active Radio-Frequency IDentification (RFID) tag,\nInternational Organization for Standardization (ISO) 15693 compliant. This approach aims to\ncontinuously measure the average, systolic and diastolic blood pressure of the small/medium\nanimals. The measured pressure wave undergoes embedded processing and results are stored\nonboard in a non-volatile memory, providing the data under interrogation by an external RFID\nreader. In order to extend battery lifetime, RFID energy harvesting has been investigated. The paper\npresents the experimental characterization in a laboratory and preliminary in-vivo tests. The device\nis a prototype mainly intended, in a future engineered version, for monitoring freely moving test\nanimals for pharmaceutical research and drug safety assessment purposes, but it could have multiple\nuses in environmental and industrial applications.
