metal whisker

基本解释

Cat whisker a fine metal thread resembling the arched shape of a cat's whisker used in early radio wave detecting crystal sets.
金属细线一种质地良好的金属线，类似于猫的胡须，呈拱形。早期应用于无线电波检测晶体装置。
It is a new international materials science development trend to add whisker into resin, metal and ceramic matrix to prepare high-performance composite materials.
以树脂，金属和陶瓷为基质，添加各种晶须构成高性能复合材料已成为目前国际材料科学发展的趋势。

To create the point-contact transistor, Shockley's team modified the cat's whisker by placing two fine metal wires close together on the surface of a germanium crystal, turning it from a diode into a triode.

This device—patented by a German scientist, Ferdinand Braun, in 1899—was made of a single metal wire, fondly called a cat's whisker, touching against a semiconductor crystal.
