Design of an infinitely stiff load cell:

In the world of small scale mechanical testing the measurement of load is one of the main challenges. There are two reasons: the first one is finding a stiff load cell in the desired regime and the second one is to be able to align it with the sample. Other than in the macroscopic world, alignment of micro- and nano-samples is a difficult task as we cannot see the samples with a microscope. Therefore it is desirable to have sensors or principles build into the load sensor which allow an alignment on the scale of the sample at hand. The design of such a sensor, paired up with a piezo actuator which allows to actively compensate for the stiffness of the load sensor is something which is missing from the micro- and nano- mechanics community and should be addressed in this thesis.
