A system for wireless power transfer and data communication of implantable bio-monitoring systems is presented. The proposed solution uses a servo-controlled power transmitter moved under the animal moving space. An$x$ -$y$ movable magnetic coil transmits the required power with a level able to keep constant the received energy by the bio-sensor system. The power is transferred via the optimized...
This paper presents the servo-controlled remote powering and low-power data communication of batteryless implantable bio-systems for freely moving animals. The required 2 mW power of the implantable system is continuously transferred by a remote powering link over 30 mm distance. The animal is tracked inside its living space and the servo-controlled rails move the external coil to follow the position...
This paper presents a remotely powered implantable heart monitoring system for freely moving animals. The system measures the blood pressure in the left ventricle of the heart and transmits the data to a database unit. The implanted unit is remotely powered over 25 mm at 8 MHz and has autonomous power control system for changing received power levels due to the moving animal. The blood pressure is...
An implantable system for monitoring vital parameters via bio-sensors inside freely moving laboratory animals and its powering system are presented. The required 2 mW are harvested by the magnetic coupling with an external coil placed under the living space of the animal. The servo X — Y rails move the external coil and track the animal. Dynamic power-adaptation keeps the harvested power level constant...
We describe an Impulse-Radio Ultra-Wide Band (IR-UWB) receiver with I/Q demodulation made of commercial off-the-shelf discrete components. It is designed to be used in a UWB testbed for measurement and algorithm validation purposes. The central frequency of the UWB signals is 4.25 GHz with a bandwidth of 500 MHz. We have achieved a data-rate of 10 Mb/s. We experimentally validate the use of the I/Q...
We demonstrate and validate that concurrent and parallel transmissions are feasible for low data-rate impulse-radio ultra-wide band (IR-UWB) physical layers. The optimal organization for a low data-rate IR-UWB network is to allow for concurrent transmissions at the link layer, and to use interference mitigation techniques at the physical layer. Indeed, low data-rate IR-UWB physical layers can suffer...
