Abstract:
Most of the widely used biopotential macroscopic and microscopic bioelectrodes do not enable proper measurements while in contact with 'problematic' tissues such as myocardial and other muscular tissues, cortical and intracavital tissues. A quantitative spherical electrode was designed as an example in the family of bioelectrodes enabling application in moving or vibrating media. The electrode developed is insensitive to its contact area. Decreasing the contact area to 40% causes 25% increase in measured resistance only. The electrode shows excellent performance in alternating current conditions combined with well defined direct current characteristics.
