Abstract:
An apparatus for measuring physiological parameters, comprising a test chamber (2) connected to at least one inlet opening and at least one outlet opening and bounded by walls, wherein at least one wall of the test chamber (2) is constructed as a first semiconductor chip (3) having an active side with planar sensors (5) facing the test chamber (2), on which biological cells (6) located in a nutrient medium can be adherently deposited in order to measure physiological parameters directly on the cells (6), wherein at least one additional sensor is allocated to a wall lying opposite the first semiconductor chip (3) in order to measure global physiological parameters, the wall lying opposite the first semiconductor chip (3) being formed by a second semiconductor chip (4) having at least the one additional sensor on its active side facing the test chamber (2), wherein a seal (7) surrounds the test chamber (2) and forms a distance spacer between the semiconductor chips (3, 4), wherein the semiconductor chips (3, 4) are held in a sealing position using a mounting (8) that grasps over them on their outer side, and wherein the semiconductor chips (3, 4) each have electric connection contacts outside of the test chamber (2), which contact with opposing contacts of the mounting (8).
