Cost-effective and compact analog compensation method of thermal drift of implantable piezoresistive blood pressure sensors

International audienceBackground: Implantable pressure sensors are important tools of preclinical research activity in laboratories. Unfortunately, their use is limited by cost, autonomy and temperature-related drifts. Cost and ease of use depend on several parameters, in particular battery life and miniaturization required to be able to implant animals and monitor them over time that is long enough to be physiologically relevant. While thermal drifts inherent in implantable sensors due to animals’ body temperature variation vary depending on their operating principe.Aim: Reduction of thermal drift and energy consumption and overall miniaturization
