Abstract
An inductive sensor system for remote powering and communication with an analyte sensor (e.g., a fully implantable analyte sensor). The system may include an analyte sensor and transceiver. The system may be ferrite-enhanced. The transceiver may implement a passive telemetry for communicating with the analyte sensor via an inductive magnetic link for both power and data transfer. The link may be a co-planar, near field communication telemetry link. The transceiver may include a reflection plate configured to focus flux lines linking the transceiver and the sensor uniformly beneath the transceiver. The transceiver may include an amplifier configured to amplify battery power and provide radio frequency (RF) power to a transceiver antenna.
