  • Patent number: 9952122
    Abstract: An electronic test plate includes a test plate comprising plurality of wells, each well configured to contain a substance to be analyzed. Sensors are arranged to sense characteristics of the substance and to generate sensor signals based on the sensed characteristics over time. The sensors are arranged so that multiple sensors are associated with each well. At least one sensor of the multiple sensors senses a characteristic of the substance that is different from a characteristic sensed by another sensor of the multiple sensors. Sensor select circuitry is arranged on a backplane disposed along the test plate. The sensor select circuitry is coupled to the sensors and enable the sensor signals of selected sensors to be accessed at a data output of the backplane.
