Regenerative shield
From Memory Alpha, the free Star Trek reference
Regenerative shields were an advanced deflector shield system used by the Federation Starfleet and the Numiri.
The warships of the Numiri were protected by regenerative shields. (VOY: "Ex Post Facto")
The battle systems of Starfleet's Prometheus-class starships included regenerative shielding, ablative armor, and the multi-vector assault mode. (VOY: "Message in a Bottle")
It is not clear if the Cardassian regenerative force field technology is synonymous with regenerative shields.

According to the Voyager novel Seven of Nine, the Borg had assimilated regenerative shield technology from an insectoid race known as the Tuktak, who used it to protect their ships. However, it proved impractical for Borg vessels, especially the very massive Borg cubes, so the Collective modified the technology for drones' personal protection instead.
