Abstract: An eye sensor, system and method for measuring fixational eye movements of an individual's eyeball (e.g., ocular microtremors and microsaccades) to provide a variable voltage biosignal for measuring the individual's brainstem activity is provided. The eye sensor comprises a sensor mounted on the individual's closed or opened eyelid so as to be deflected by the fixational eye movements of the eyeball. A shielded flexible ribbon assembly supplies the biosignal generated by the sensor to an amplifier located on the individual's skin where the biosignal is amplified. The amplifier is interconnected with a signal processor and a display by which graphical and numerical representations of the biosignal are made accessible to an anesthesiologist, intensivist or clinician. A method for analyzing the biosignal to determine the brainstem activity of a patient is also provided.

Abstract: An ocular micro tremor (OMT) sensor, system and method for measuring micromovements of an individual's eyeball having an amplitude of 40 micrometers or less to provide a variable voltage biosignal for measuring the individual's brain stem activity. The OMT sensor includes a flexible piezo-active sensing element mounted at the individual's closed or opened eyelid so as to be deflected by the micromovements of the eyeball. A shielded flexible ribbon assembly supplies the biosignal generated by the piezo-active sensing element to an OMT amplifier located on the individual's skin where the biosignal is amplified. The OMT amplifier is interconnected with a signal processor and a display by which graphical and numerical representations of the biosignal are made accessible to an anesthesiologist, intensivist or clinician.
