A fast method to estimate body capacitance to ground
Aliau Bonet, Carles; Pallàs-Areny, Ramon (2012)
Text en actes de congrés
Accés obert -
A fast method to estimate body capacitance to ground at mid frequencies
Aliau Bonet, Carles; Pallàs-Areny, Ramon (University of Oslo, 2015-12-18)
Article
Accés obertImpedance measurements that involve the human body are affected by the capacitance between the body and earth ground. This paper describes a fast method to estimate that apacitance at 10 kHz, which is valid for impedance ... -
Cost-effective autonomous sensor for the long-term monitoring of water electrical conductivity of crop fields
Serrano Finetti, Roberto Ernesto; Aliau Bonet, Carles; López Lapeña, Oscar; Pallàs-Areny, Ramon (2019-10-01)
Article
Accés obertSalinity is a key parameter determining water quality. In agriculture, irrigation water with high salinity levels impacts plant growth and yield negatively hence there is a need to monitor it and irrigate with fresh water ... -

Effects of interelectrode capacitance in water conductivity measurements with capacitive electrodes
Pallàs-Areny, Ramon; Aliau Bonet, Carles (2015)
Text en actes de congrés
Accés obert -
Effects of stray capacitance to ground in bipolar material impedance measurements based on direct-contact electrodes
Aliau Bonet, Carles; Pallàs-Areny, Ramon (2014-10-01)
Article
Accés restringit per política de l'editorialBipolar material impedance measurements are easier to implement than tetrapolar measurements but are more affected by electrode impedance. This effect can be reduced by measuring at a high-enough frequency albeit with the ... -
Effects of stray capacitance to ground in bipolar water impedance measurements based on capacitive electrodes
Pallàs-Areny, Ramon; Aliau Bonet, Carles (2015)
Text en actes de congrés
Accés obertLiquid impedance measurements based on capacitive (or contactless) electrodes Overcome electrode polarization problems but are affected by stray capacitance from the material being measured to ground, the same as measurements ... -
Effects of stray capacitance to ground in impedance measurements
Aliau Bonet, Carles; Quílez Figuerola, Marcos (Elsevier, 2021)
Capítol de llibre
Accés restringit per política de l'editorialInductive effects such as positive phase angles in impedance measurements have often confused the researchers when the material measured is nonmagnetic. When the measurement is based on auto-balancing bridge method and the ... -
Effects of stray capacitance to ground in three electrode monopolar needle bioimpedance measurements
Kalvøy, Håvard; Aliau Bonet, Carles; Pallàs-Areny, Ramon; Martinsen, Ørjan G (Institute of Electrical and Electronics Engineers (IEEE), 2015)
Comunicació de congrés
Accés obertPositive phase angle is documented and analyzed in a three electrode monopolar needle measurement. Inductance equivalent behavior of the stray capacitance to ground is described as error source in a non-inductive sample ... -

Aliau Bonet, Carles; Pallàs-Areny, Ramon (2014)
Text en actes de congrés
Accés restringit per política de l'editorialImpedance measurements that involve the human body are affected by the capacitance between the body and earth ground. This paper describes a low-cost method to estimate that capacitance that can be applied to impedance ... -
Mesura de la conductivitat de l'aigua amb elèctrodes capacitius
Aliau Bonet, Carles (Universitat Politècnica de Catalunya, 2015-12-21)
Tesi
Accés obertElectric conductivity is a good estimator of water quality. It can be measured by using cells with direct contact between the electrodes and the electrolyte, inductive cells or cells with capacitive electrodes. The use of ... -

Transient Reduction in pulse-based impedance measurements,
Aliau Bonet, Carles; Pallàs-Areny, Ramon (2013)
Text en actes de congrés
Accés obertImpedance measurements based on voltage pulse injection and current detection are faster and easier to implement than measurements based on sine waves, but transients produced in the current-to-voltage conversion may lead ...
