Abstract
A multi-modality sensor for physiological characterization of cells can include an array of sensing pixel groups, each sensing pixel group comprising an array of sensing pixels; a plurality of signal conditioning blocks, each signal conditioning block coupled to a corresponding one sensing pixel group of the array of sensing pixel groups to process outputs of that sensing pixel group; and a controller providing signals for independent configuration of sensing modalities for each pixel of each sensing pixel group. The pixels of the multi-modality sensor support at least two sensing modalities by including an op amp that can be shared by at least two sensing circuits and including a photodiode. A cellular culture can be applied to the multi-modality sensor and a biological measurement can be performed on the cellular culture using at least two sensing modalities of the multi-modality sensor.
