Resistive touchscreen — Resistive touchscreens are composed of two flexible sheets coated with a resistive material and separated by an air gap or microdots. When contact is made to the surface of the touchscreen, the two sheets are pressed together, registering the… … Wikipedia
Resistive skin time — The resistive skin time is a characteristic time of typical magnetohydrodynamic (MHD) phenomena. Definition The resistive skin time is defined as: au R=frac{mu 0 a^2}{eta}where eta is the resistivity, a is a typical radius of the device and mu 0… … Wikipedia
Resistive ballooning mode — portalpar|PhysicsThe resistive ballooning mode (RBM) is an instability occurring in magnetized plasmas, particularly in magnetic confinement devices such as tokamaks, when the pressure gradient is opposite to the effective gravity created by a… … Wikipedia
Nanoionic device — Nanoionic devices belong to a new class of solid state devices operating due to fast ion transport at nano scale. The examples of such devices are nano switches with quantum conductance[1][2], and nanoionic supercapacitors with coherent… … Wikipedia
