Data's computerized breastplate.

A computerized breastplate was a piece of wearable technology in 2015, which could be programmed to produce certain sound effects.


One of these breastplates was worn by a member of Griff Tannen's gang, Rafe "Data" Unger. He used it to produce the sound of a chicken clucking when the gang used this insult against Marty McFly.

Behind the scenes

  • Back to the Predictions refers to Data's computerized breastplate as a chest-based soundboard.[1]


  • An app that performs the same function as the computerized breastplate worn by Data in Back to the Future Part II is available for such devices as smartphones and tablet computers.
