Relative Measurement of Differential Electrode Impedance for Contact Monitoring in a Biopotential Amplifier 601 Relative Measurement of Differential Electrode Impedance for Contact Monitoring in a Biopotential Amplifier
In this paper, we propose a simple and relative electrode contact monitoring method. By exploiting the power line interference, which is regarded as one of the worst noise sources for bio-potential measurement, the relative difference in electrode impedance can be measured without a current or voltage source. Substantial benefits, including no extra circuit components, no degradation of the bod...
متن کاملDevelopment of Hydrogel Membranes for Long Term Biopotential Monitoring Using Flexible Wet Electrodes
Ubiquitous monitoring of biopotentials can greatly enhance comfort, health and safety of patients dealing with chronic diseases. For home use, clinical grade adhesive electrodes are often cited as irritating and uncomfortable, leading to low usage compliance [1]. For long-term monitoring it is mandatory to have innocuous and disposable electrodes with constant impedance over long periods of tim...
متن کاملSignal Quality in Dry Electrode EEG and the Relation to Skin-electrode Contact Impedance Magnitude
Current EEG research approaches are focusing on developing new dry electrode EEG (electroencephalogram) systems providing a high enough signal quality for a wide range of applications. This study proposes several parameters for evaluating signal quality of dry electrodes and relates the results to skin-electrode contact impedance magnitude values. The EEG recordings of a Ag/AgCl pinned electrod...
متن کاملAn active electrode for biopotential recording from small localized bio-sources
BACKGROUND Laser bio-stimulation is a well-established procedure in Medical Acupuncture. Nevertheless there is still a confusion as to whether it works or the effect is just placebo. Although a plethora of scientific papers published, showing positive clinical results, there is still a lack of objective scientific proofs about the bio-stimulation effect of lasers used in Acupuncture. The object...
متن کاملA dry electrophysiology electrode using CNT arrays
We describe the design of a dry electrode sensor for biopotential measurement applications (ENOBIO) designed to eliminate the noise and inconvenience associated to the use of electrolytic gel. ENOBIO uses nanotechnology to remove gel-related noise, as well as maintaining a good contact impedance to minimise interference noise. The contact surface of the electrode will be covered with an array/f...
