1. A sensor adapted for placement adjacent to tissue to be tested, comprising:
- at least one light emitter and at least one light detector capable of acquiring physiological data from a patient;
a deformable integrated circuit comprising an analog-to-digital converter coupled to an output of the at least one light detector and configured to output a digital signal corresponding to the physiological data from the patient; and
a flexible outer covering configured to be placed adjacent the tissue of a patient and to house the deformable integrated circuit and the emitter and the detector.
