Graphene-Enabled Electrodes for Electrocardiogram Monitoring
The unique parameters of graphene (GN)-notably its considerable electron mobility, high surface area, and electrical conductivity-are bringing extensive attention into the wearable technologies. This work presents a novel graphene-based electrode for acquisition of electrocardiogram (ECG). The proposed electrode was fabricated by coating GN on top of a metallic layer of a Ag/AgCl electrode usin...
متن کاملMeasuring Breakdown Probabilities of Sf6 Insulated, Low Inhomogeneous Electrodes
It is well known that increased surface roughness of SF6 insulated electrode arrangements is significantly lowering the breakdown voltage [1], [2]. This effect becomes stronger with rising pressure and homogeneity of the electrodes. Since each breakdown changes the surface condition of the electrodes, it becomes very ambitious to measure breakdown probabilities in a statistical meaningful way. ...
متن کاملAbdominal Electrodes Analysis by Statistical Processing for Fetal Electrocardiogram Extraction
Obstetricians were asking the engineering support to study more extensively any technical possibility to electronically get some useful information from the whole PQRST complex of the fetal electrocardiogram (fECG) in order to identify eventual sign of fetal distress (FD). The latter should indeed be found as a more reliable information for the clinician with the potential benefit of increasing...
متن کاملCan electrocardiogram electrodes replace bispectral index electrodes for monitoring depth of anesthesia?
BACKGROUND Bispectral index has been introduced to provide optimal level of anesthesia. However, Bispectral index monitoring may not be cost effective in a relatively short procedures due to the high costs of the electrode. The authors conducted the present study to compare the feasibility of commercially available electrocardiogram (ECG) electrodes instead of the Bispectral index (BIS) monitor...
متن کاملElectromagnetic Initiation and Propagation of Bipolar Radiofrequency Tissue Reactions via Invasive Non-Insulated Microneedle Electrodes
Radiofrequency (RF) energy can be emitted into the skin, either non- or invasively, via a monopolar mode that utilizes an active electrode and a grounded electrode or via a bipolar mode that employs two active electrodes. In this experimental study of RF tissue reactions, bipolar RF energy was emitted in vivo to micropig skin at varying microneedle penetration depths, signal amplitudes, and con...
