Simple voltage-controlled current source for wideband electrical bioimpedance spectroscopy: circuit dependences and limitations
Seoane, F.; Macías Macías, Raúl; Bragós Bardia, Ramon; Lindecrantz, K. (2011)
Article
Accés restringit per política de l'editorialIn this work, the single Op-Amp with load-in-the-loop topology as a current source is revisited. This circuit topology was already used as a voltage-controlled current source (VCCS) in the 1960s but was left unused when ... -
Textile electrode characterization: Dependencies in the skin-clothing-electrode interface
Macías Macías, Raúl; Fernández Chimeno, Mireya; Bragós Bardia, Ramon (IOPScience, 2013)
Text en actes de congrés
Accés restringit per política de l'editorialGiven the advances in the technology known as smart textiles, the use of textile electrodes is more and more common. However this kind of electrodes presents some differences regarding the standard ones as the Ag-AgCl ... -
