Vanlerberghe, F and De Volder, M and de Beeck, MO and Penders, J and Reynaerts, D and Puers, R and Van Hoof, C (2011) 2-Scale topography dry electrode for biopotential measurements. In: UNSPECIFIED pp. 1892-1895..Full text not available from this repository.
The design and fabrication of a novel 2-scale topography dry electrode using macro and micro needles is presented. The macro needles enable biopotential measurements on hairy skin, the function of the micro needles is to decrease the electrode impedance even further by penetrating the outer skin layer. Also, a fast and reliable impedance characterization protocol is described. Based on this impedance measurement protocol, a comparison study is made between our dry electrode, 3 other commercial dry electrodes and a standard wet gel electrode. Promising results are already obtained with our electrodes which do not have skin piercing micro needles. For the proposed electrodes, three different conductive coatings (Ag/AgCl/Au) are compared. AgCl is found to be slightly better than Ag as coating material, while our Au coated electrodes have the highest impedance.
