CROSS-SENSITIVITY-COMPENSATED BIOSENSOR

摘要

Embodiments of the invention include a biosensor, such as an implantable biosensor, that includes a sensor material sensitive to at least one analyte in a pressure measurement chamber coupled to a pressure sensor. In embodiments of the invention, a pressure prevailing in the pressure measurement chamber may be determined by the pressure sensor. The sensor material is coupled in the pressure measurement chamber to a compensation material, which includes a relationship between a temperature and a volume of the pressure. The relationship is opposite to a temperature-dependent change in pressure or volume of the sensor material and at least partially compensates for a cross-sensitivity-induced change in volume of the sensor material.
