In-vitro RF characterization of implantable telemetry system.

We present the discrete prototype version of our wireless telemetry system architecture, which is suitable for custom IC implementation and intended to eventually retrieve blood pressure and volume (PV) data from small animal subjects (e.g., mice, rats). The architecture consists of four system level blocks that are stacked in $$2.475\,{\hbox{cm}}^{3}$$ volume and it weights 4.0 g. The current prototype's size is well suited for commercial implementation inside medium sized animal subjects, for instance, rabbits and larger rats. Transmit power reported in this paper is tested between 0 to $$-$$ 20 dBm by using phantom tissue model. [ABSTRACT FROM AUTHOR]
