Plural of coherer; multiple devices for detecting radio waves or multiple agents that cause cohesion.
From coherer + -s plural suffix. The plural form is straightforward, developing naturally as multiple such devices became common in early wireless research.
In the 1890s, physicists competed to improve coherers—it became like an arms race in early radio technology, with each scientist trying to build a more sensitive version to win the wireless telegraphy game.
