Question

Are there inertial dampeners in real life, or in the making?

Answer 1

Nope.  Inertia is as fundamentally a part of matter as gravity, so don't go looking for inertial dampers until we've figured out how to levitate.

Answer 2

An Inertial Dampener is a Sci-Fi plot devices base loosely on the concept behind a tuned mass damper, Tuned mass dampers are massive devices that are used to counteract the swaying motions of skyscrapers in windy conditions,

In Scf-fi the inertial dampener is a quick explanation for why the crew doesn't splatter against a bulkhead when the ship takes evasive action.

Answer 3

In a way, you could think of seat belts, shock absorbers, air bags, and other such buffering devices as inertial dampeners. They all provide a means to counteract the movement your body would otherwise experience.
