Ultra-High Input Impedance, Low Noise Integrated Amplifier for Noncontact Biopotential Sensing

Noncontact electrocardiogram/electroencephalogram/ electromyogram electrodes, which operate primarily through capacitive coupling, have been extensively studied for unobtrusive physiological monitoring. Previous implementations using discrete off-the-shelf amplifiers have been encumbered by the need...
