combadge
Star Trek: The Next Generation
Episode: TNG 101 - Encounter at Farpoint, Part I
The popular term for the modern Starfleet communicator when incorporated as a single unit with a chest insignia badge -- as opposed to original models which evolved as a separate unit that was standard landing party gear.
The combadge has assumed different styles over the years since its 24th century inception , beginning with the longtime maroon uniform series style's chest pin by 2344 and later the simpler silver arrowhead design by the early 2350s. The arrowhead was backed by a gold housing, initially in an elliptical oval that was replaced by an angular-backed shape introduced in 2371.
