Hi, I am aware that in the traditional sense Piezoelectric crystals/ceramics cannot be used to measure static/steady state forces. However, I was wondering how low their frequency response can go. That is, is it possible to measure a force of maximum strength 1mN that will develop from zero slowly (over a period of about 0.5-1second) to maximum strength and then dissipate over the same period. I am worried that my signal will get lost due to the (of course) non-infinite impedance of voltage measuring equipment. Is my fear justified? Can such a "slowly" varying force be measured? This is my first foray into the world of such sensitive measurements and any help or suggestions would be appreciated. Thanks.
