Claim:
1. A probe-based system for the combined mechanical and electrical testing of a MEMS structure, the system comprising: at least one motorized multi-axis micropositioning unit having position encoders generating signals, and at least one additional micropositioning unit; a microforce sensor mounted on said at least one motorized multi-axis micropositioning unit and configured to probe the MEMS structure and generate an output signal; a rotatable adapter piece mounting said microforce sensor on said at least one motorized multi-axis micropositioning system and permitting said microforce sensor to change between vertical testing and horizontal mechanical testing or testing at any other angle; at least one electrical probe mounted on said at least one additional micropositioning unit and configured to apply electrical signals or to measure electrical signals at one or multiple locations on the MEMS structure and to generate signals; at least one microscope being tilted for visualization of a perspective view or a side view of the MEMS structure; a data acquisition unit configured to record the output signal generated by said microforce sensor, the signals generated by said position encoders and the signals generated by said at least one electrical probe; and a sample holder on which the MEMS structure to be tested is mounted.
