SIS ELECTROTHERAPY ELECTRODES round (4 pack)
SIS 4.7cm (1.87 inch) diameter circular silver-nylon active stimulation area. Excellent for Cranial Electrical Stimulation (CES), accupuncture points or general electrostimulation therapy. Provides silver ions for antibacterial effects. 


Unique SIS Electrode Features

• Far higher electrical conductivity (5-400×, typical 100×) than standard electrotherapy electrodes:
• Total bioelectrical circuit resistance on intact skin below 50 kiloOhms as standard and below 10 kiloOhms normally achievable.
• Electrodes are applied with tap water and standard fixation tape.
• SIS electrodes can conduct lower intensity and higher precision stimulation direct Output Currents and frequency based stimulation, using far lower voltages.
• Optimal for extended applications.
• Improved skin protection; electrodes can also be used over standard wet gauze.
• Originally designed to meet the requirements and appropriate for high precision surface wound stimulation.

Further information
Typical self-adhesive hydrogel electrodes placed in contact with intact skin typically contribute between 1-2 and up to 4 megaOhms (4,000,000) of electrical resistance per pair. SIS electrodes typically contribute only 20-50 kiloOhms (50,000) under the same conditions.

Translated to clinical application, this means that to deliver 10 microAmperes of electric current (microcurrent) into the body with hydrogel electrodes would need 20 volts, which would damage skin and cells. In reality, with a lower applied stimulation voltage, that much current never conducts through the body. Using the SIS electrodes, only 0.2-0.5 volts would be needed to conduct the same microcurrent.
