Miniaturized and low-power blood pressure telemetry system with RFID interface

This work deals with the development of an implantable blood pressure telemetry system, based on an active RFID tag, ISO 15693 compliant, aimed to continuously measure the average, systolic and diastolic pressure. The pressure wave undergoes embedded processing and results are stored onboard in a non-volatile memory, providing the data under interrogation by an external RFID reader. The paper presents the experimental characterization in a laboratory and preliminary in-vivo tests. The device is mainly intended for monitoring freely moving test animals for pharmaceutical research and drug safety assessment purposes, but it could have multiple uses in environmental and industrial applications.
