Hello to everybody! I’m new in this forum.
My experience in robot kits is not so large. For this reason I’m asking your help.
I’m working on a robotic gripper home project. My question is:
Where I can find an array of pressure sensors for a gripper (for example the Lynxmotion gripper)? It does exist? It is low cost? Maybe an array of 2 by 2 or 4 by 4 elements can be enough. I need this type of array to do a sort of simple manipulation task.
Thank you very much
The below link has some info. Do you need pressure sensor or a contact sensor to know when something is gripped?
The FSR in the LM reference (FSR-01) is fairly small, .2" I think.
Trossen Robotics has a few:

Look up IFSR ((Interpolating Force-Sensitive Resistance), they replace arrays of FSR sensors.
You’d have to make your own array of them, i think. You might consider making your own FSR, from some sort of resistive paint, and a thin mylar or plastic substrate. Such resistive paints are/were used for making PCBs as I recall.
How about a membrane pot? Maybe two in an ‘X’ configuration?

Thanks zoomkat, thanks km6vv.
Yes, I need pressure sensor and not only contact sensor.
Yes, I thought about FSR (0.2" for example) but it’s not so simple and compat to put 4 or 8 of them on each part of a Lynxmotion gripper.
Can FSR detect static force? Are they affected by temperature?
IFSR are interesting but there is not a dimension right for a Lynxmotion gripper
The FSR should be OK for a gripper, there is even a tutorial for it, as I recall. I’d check that out before going to too much effort to find a substitute.
It is a resistive element, it will report a static pressure. It shouldn’t be affected by temperature. Check the specs.

He wants an array of sensors so he can manipulate an object.
Robot Dude you are right!
