This paper describes a wireless multi-channel system for zero-prep electroencephalogram (EEG) measurements in operational settings. The EEG sensors are based upon a novel hybrid (capacitive/resistive) bioelectrode technology that requires no modification to the skin's outer layer. High impedance techniques developed for QUASAR's capacitive electrocardiogram(More)
BACKGROUND As is well known, in order to optimally manage diabetes mellitus, monitoring blood glucose levels several times daily is recommended so appropriate actions can be taken to maintain these levels within a near-normal physiologic range. One technique that shows promise is the use of optical polarimetry. This technique has the potential to(More)
This paper describes measurements made using an ECG system with QUASAR's capacitive bioelectrodes integrated into a pad system that is placed over a chair. QUASAR's capacitive bioelectrode has the property of measuring bioelectric potentials at a small separation from the body. This enables the measurement of ECG signals through fabric, without the removal(More)
