My question is mainly the following:
Is there a force-sensitive resistor that can handle pressure (like 50kg weight) constantly on it? While not having its response curve altered because of this?
Well, the backstory of the problem is that I have been using normal force sensitive resistors like these, and the problem they have is that if you apply the pressure on them constantly, their response curve will flatten out and you will no longer be able to detect minute changes in the pressure. This limitation is also discussed in their datasheet. So my question is: What alternatives do you think I have, to circumvent this issue?
What I am trying to accomplish:
I want to have a force-sensitive resistor, similar to the one I mentioned before. The only problem with the one above, is that if I constantly apply pressure on it (or apply pressure on it over long periods of time), the resistance curve becomes almost a flat line and I will no longer be able to use it. I want something that presents the same behavior as the force sensitive resistor above, however, is more durable when a DC force is constantly being applied on it.
