Mathematical model predicting the heat and power dissipated in an electro-conductive contact in a hybrid woven fabric [PDF]

open access: yes, 2020
Electro-conductive (EC) yarns can be woven into a hybrid fabric to enable electrical current to flow through the fabric from one component A to another component B. These hybrid fabrics form the bases of woven e-textiles.

Case Study about the Energy Absorption Capacity of Metal Oxide Varistors with Thermal Coupling

open access: yesEnergies, 2019
Metal oxide varistors are applied today inside modern surge arresters for overvoltage protection for all voltage levels. Their main issue is the thermal activation of their crossing current, which could lead to complete destruction by thermal runaway ...

Current limiting and negative differential resistance in indium oxide based ceramics [PDF]

open access: yes, 2009
Indium oxide based ceramics with bismuth oxide addition were sintered in air in the temperature range 800-1300 ºC. Current-voltage characteristics of In2O3-Bi2O3 ceramics sintered at different temperatures are weakly nonlinear.

Varistors: A Useful Tool for Superconducting Magnet Quench Protection

open access: yesIEEE transactions on applied superconductivity, 2021
A perfect varistor is a constant voltage resistor as a function of current through the resistor. A perfect varistor can't exist, because its resistance would be infinite at zero current. In electronic devices, varistors are often used as surge protectors.
