Abstract
The need of continuous real-time monitoring device for in-vivo drug level detection has been widely articulated lately. Such monitoring could guide drug posology and timing of intake, detect low or high drug levels, in order to take adequate measures, and give clinicians a valuable window into patients' health and their response to therapeutics. This paper presents a novel implantable bio-sensor based on impedance measurement capable of continuously monitoring various antiepileptic drug levels. This portable point-of-care microsystem replaces large and stationary conventional macrosystems, and is a one of a kind system designed with an array of electrodes to monitor various anti-epileptic drugs rather than one drug. The micro-system consists of (i) the front-end circuit including an inductive coil to receive energy from an external base station, and to exchange data with the latter; (ii) the power management block; (iii) the readout and control block; and (iv) the biosensor array. The electrical circuitry was designed using the 0.18-um CMOS process technology intended to be miniature and consume ultra-low power.
