The combined changes between electrodermal resistance and electrodermal potential make up electrodermal activity. Galvanic skin resistance (GSR) is an older term that refers to the recorded electrical resistance between two electrodes when a very weak current is steadily passed between them. The electrodes are normally placed about an inch ...
Skin effect reduces the effective cross-section of the conductor and thus increases its effective resistance. At 60 Hz in copper, skin depth is about 8.5 mm. At high frequencies, skin depth becomes much smaller. Increased AC resistance caused by skin effect can be mitigated by using a specialized multistrand wire called litz wire. Because the ...
GSR may refer to: Law and Legal ... Galvanic skin response, physiological phenomenon; Glutathione-disulfide reductase, enzyme; Gunshot residue; Organizations.
The E-Meter (also electropsychometer and Hubbard Electrometer) is an electronic device used in Scientology that allegedly "registers emotional reactions". [1] After claims by L. Ron Hubbard that the procedures of auditing, which used the E-Meter, could help heal diseases, the E-Meter became the subject of litigation.
EDA used to be known as the galvanic skin response, which is the combination of the changes in the galvanic skin resistance and galvanic skin potential. The polygraph measures the EDA, respiration and heart rate.
Galvani's name also survives in everyday language as the verb 'galvanize' as well as in more specialized terms: Galvani potential, galvanic anode, galvanic bath, galvanic cell, galvanic corrosion, galvanic couple, galvanic current, galvanic isolation, galvanic series, galvanic skin response, galvanism, galvanization, hot-dip galvanization ...
In some cases, biofeedback does not match EEG, while parameters such as electromyography (EMG), galvanic skin resistance (GSR), and heart rate variability (HRV) can do so. Many biofeedback systems treat disorders such as attention deficit hyperactivity disorder (ADHD) , sleep problems in children, teeth grinding, and chronic pain.
A galvanic cell's anode is less negative, supplying less energy than thermodynamically possible. A galvanic cell's cathode is less positive, supplying less energy than thermodynamically possible. The overpotential increases with growing current density (or rate), as described by the Tafel equation. An electrochemical reaction is a combination ...
