A thin-film electrochemical sensor electrode capable of electrolytic conductivity, cyclic voltammetry, and temperature measurements of electrolyte solutions has been fabricated and characterized. The electrode fabrication and calibration is detailed, showing accuracies of 6 % for electrolytic conductivity measurements over the range of 0.1–100 mS cm 1 and temperature measurement within 2 C from...

A multi-scale/multi-material computational model for simulation of the electric signal detected on the electrodes of a metal–oxide–semiconductor (MOS) capacitor forming a nanoscale artificial membrane, and containing a nanopore with translocating DNA, is presented. The multi-scale approach is based on the incorporation of a molecular dynamics description of a translocating DNA molecule in the n...

Electrolytic and metallized polypropylene film (MPPF) capacitors are among the most popular capacitors used in electronic equipments. The choice of capacitors is of major importance because one of the most frequent causes of the equipment breakdowns results from the failure of capacitors, and will therefore determine the overall lifetime of the system. Electrolytic capacitors present higher cap...

This work focuses on the estimation of the Remaining Useful Life (RUL) of aluminum electrolytic capacitors used in electrical automotive drives under variable and nonstationary operative conditions. The main cause of the capacitor degradation is the vaporization of the electrolyte due to a chemical reaction. Capacitor degradation can be monitored by observing the capacitor Equivalent Series Res...

Electrolytic capacitors are used in several applications ranging from power supplies on safety critical avionics equipment to power drivers for electromechanical actuators, and this makes them good candidates for prognostics and health management research. Prognostics provides a way to assess remaining useful life of components or systems based on their current state of health and their anticip...

This paper proposes first principles based modeling and prognostics approach for electrolytic capacitors. Electrolytic capacitors and MOSFETs are the two major components, which cause degradations and failures in DC-DC converters. This type of capacitors are known for its low reliability and frequent breakdown on critical systems like power supplies of avionics equipment and electrical drivers ...
