Since I just learned about peristaltic pumps, thinking about how to create an artificial oesophagus for semi-solid slurry based on the principle. I’m thinking a synchronized cam chain on a single drive…

TIL: peristaltic pumps that work by squeezing a flexible transport tube rather than forcing fluid through an impeller. This is clearly what I need for an artificial esophagus, except perhaps several on the same tube in series? adafruit.com/product/1150

or maybe like a helical cage with little wheels that press on the tube so the action would be kinda like putting your fingers around it and pulling along the length of it while twisting

This idea is interestingly like the duality of e-m fields (moving conductor in magnetic field generates current, varying current in magnetic field moves a conductor)
