Tension pistons are pistons that use soft flexible materials to deliver greater forces with higher energy efficiencies.

In their construction a flexible membrane is used, that encloses a compressible rigid structure to transmit the induced fluid pressure forces.

Replacing the conventional rigid elements of a piston with a mechanism that uses compressible structures inside a membrane leeds to increased tension forces while most of the friction is eliminated and in the low pressure domain they can even provide better energy efficiency.

At the same time, new geometries can be explored that require piston flexibility.
