I immediately thought this.

The whole thing seems like such an intuitive idea. I really like the idea of mixing sizes to induce multiple pressure “plateaus”.

Also the drama of its inception is delectable.

The paper linked in another comment has some excellent visual aides. Wish we had a video.

The paper’s graphs show a hysteresis that looks a lot like many semiconductor curves. What a neat technology, this might make for some interesting hydraulic control solutions.
