1. A bio imaging system, comprising:
a light emitter array including a plurality of light emitters configured to irradiate light;
a sensor array including a plurality of sensors configured to detect light scattered or reflected by internal tissue of a living body; and
a stretchable substrate, the stretchable substrate configured to support the plurality of light emitters and the plurality of sensors,
wherein each sensor of the plurality of sensors includes a plurality of photo-detecting elements stacked on each other as a stack of photo-detecting elements on the stretchable substrate, such that the plurality of sensors includes a plurality of stacks of photo-detecting elements,
wherein, in each stack of the plurality of stacks, the plurality of photo-detecting elements of the stack have different absorption peak wavelengths in relation to each other, and
wherein the light emitter array and the sensor array are at different heights from the stretchable substrate, such that at least one light emitter of the plurality of light emitters at least partially overlaps at least two stacks of photo-detecting elements of the plurality of stacks of photo-detecting elements in a direction extending perpendicular to the stretchable substrate.
