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 remote powering link at 13.56 MHz. The received AC signal is converted to DC voltage with a passive full-wave integrated rectifier and the voltage regulator supplies 1.8 V for the implantable sensor system. The sensor control and read-out circuit measures the current on the bio-sensors and transmit the data to the transmitter. The sensor data is transmitted to an external reader by a low-power OOK transmitter and received by a custom designed receiver at 869 MHz. The results are shown in a tablet computer in real time continuously. The long-term characterization of the implantable system is verified by a fully bio-compatible packaged implant with 30 days measurement. A complete prototype is also presented to prove the overall system performance with experimental in-vitro measurement.Analog circuit designdata communicationimplantable biomedical systemintegrated circuitsintelligent remote poweringservo-controlled x and y railspower managementwireless power transferbio-sensorslong term continuous monitoringbiocompatible packagingdrug monitoringglucose monitoringanimal monitoringanimal implanttext::journal::journal article::research article
