Star Trek: The Next Generation, Picard Emergency Transporter Armband

original movie prop

In the episode Timescape, Picard, Data, Troi, and La Forge adapt emergency transporter armbands to generate skin-tight forcefields, protecting them from the effects of temporal fragmentation as they investigate a temporal anomaly which has slowed time onboard the Enterprise to a crawl, moments before its destruction by a warp core breach.

Resin, acrylic, and elastic. This piece was worn by Patrick Stewart, bearing his first name on the inside of the elastic band.
