I am working on the deflection measurement with an application of load in the range of mili-newton. The cantilever thin film is deflected by a probe. The deflection can be measured by a build-in micrometer. Now I am seeking a method to measure the contact force. The PZT tranceducer(or force sensor) is considered to be used. However, since the size of the thin film as well as the tip of the probe is very small(in the order of 50 micrometers), I do not know how to mount the PZT. Does anyone know how to do that? Or any other suggestions about measuring force? Thanks in advance.
