Terminal voltage fluctuation of lithium-sulfur cells and nickel-metal-hydride cells was measured in different time intervals since cell charging to full capacity. The power noise spectral density is of 1/fα type with exponent a varying in the range from 1 to 1.8. The main noise sources in charge storage systems are: i) fluctuation of potential barrier on the electrode-electrolyte interface (its height...
Nitrogen dioxide (NO2) is a highly toxic gas harmful to the environment even at low concentrations. To overcome limitations of standard solid NO2 sensors based on inorganic materials, a fully printed sensor with solid polymer electrolytes (SPE) was developed in Regional Innovation Centre for Electrical engineering in Czech Republic. The amperometric sensor is based on a semi-planar three-electrode...
Nitrogen dioxide (NO2) is a highly toxic gas harmful to the environment, which can be threat to human health even at low concentrations. To overcome limitations of standard solid NO2 sensors based on inorganic materials, a new sensor with solid polymer electrolytes (SPE) was developed. Our study deals with investigation of fluctuation phenomena in the electrochemical NO2 sensor, which is based on...
