摘要：
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.
