Preliminary technological assessment of microneedles-based dry electrodes for biopotential monitoring in clinical examinations

摘要: Abstract Monitoring biosignals, such as in electrocardiography (ECG), electromiography (EMG) and electroencephalography (EEG), is important for a better understanding of the pathological physiological conditions human subjects. In clinical practice recording biopotentials carried out general with wet electrodes, considered golden standard, although they have shown some limits: (i) susceptibility to motions artifacts, critical aspect ECG EMG monitoring, (ii) time-consuming procedure be applied EEG examinations, (iii) inability record biosignals long-term applications. past years innovative solutions been suggested, among which microstructured dry electrodes showed very promising features. This study represents first technological assessment novel type microneedles-based electrodes. this paper it has proved that these electrodes: seem allow electro-mechanical interface skin, performance comparable EEG, static signals, showing an improvement monitoring signal dynamic conditions, do not need long-lasting skin preparation applications, appearing easy use apply. conclusion, our microneedles based alternative standard examinations.
