Applied pressure through fluid to measure strain

Click For Summary
SUMMARY

The discussion focuses on the feasibility of applying fluid pressure to curved soft tissue, specifically silicon, to measure strain using pressure sensors. It is established that if pressure sensors are utilized, they would initially read the same pressure across the surface. However, variations in pressure due to the application of fluid can provide insights into the strain experienced by the material. The conversation emphasizes the importance of sensor placement and the interpretation of readings before and after pressure application.

PREREQUISITES

Hello,

I would like to ask if its possible to apply pressure through fluid on a curved soft tissue such as silicon to measure the strain by using sensors (and what kind) such as shows in the attached image?
If those were pressure sensors would they all show the same pressure or would the change of pressure could create a picture of the strain.

Additional details:
Stage 1 is before applying pressure
Stage 2 is after applying pressure
The sensors take readings before and after stage 1 & 2

Any more direction to research and read would be appreciated as well

Thanks!

If I have understood your diagram correctly.. all the sensors would read the same pressure.
