Hey guys/gals so here is my problem, I am trying to be able to passively measure the mechanical vertical deflection of fluid passing through an elastic tube approx 1cm in diameter with 0.5mm thick wall that is embedded into the surface of a gelatin mold. Pressure of the flow through the tube varies from a high of 220mmHg down to no flow but can be anywhere between those two value. The flow through the elastic tube occurs in a pulsatile pattern.
I was thinking of just taping a flat strain gauge or thin filament type stretch sensor to the tube perpendicular to the direction of flow to measure the vertical deflection and then correlating the vertical deflection/pulse to the pressure of flow below.
The end readout I'm trying to get is just the pressure of the pulsatile flow in the elastic tube. The physical constraint is that it has to be something I can essentially tape to the surface of the tube pretty easily.
Any ideas? Geniuses out there. . . assemble!
Thanks in advance!
