These are just force fields for furniture, except not as nerdy. NERRRRRRRDS
There's this trend for sci fi fans to want certain implausible things. They want teleporters that move the original without destroying it and making a copy elsewhere. They want laser guns that go PEW PEW instead of a slow steady BRRRRRRRRRRROT. They want aliens who say things like "I find you humans most impressive" instead of "Ugh, you Earth-things are the WORST!" And they want force fields that can stop anything... even tears.
We can't promise the first three will ever happen, but if you want that last one you can look no further than some furniture protectors. They're like force fields, but made of plastic, keeping your expensive furniture free from spills, dirt, alien spit-up, and yes, even tears.
Because nerds are sensitive people, you know. And when someone tells you a transporter is unlikely to happen in your lifetime, that digs up a lot of emotion.
