Nanoindentation is a material testing method frequently used for studies of mechanical properties on the nano scale. Today, nanoindentation is also performed in situ a Transmission Electron Microscope (TEM), in order to simultaneously monitor the substrate with high resolution imaging. Here we present an extension of TEM-Nanoindention, utilizing custom designed MEMS sensor for in situ TEM use that enables simultaneous force and current measurements. The sensor is intended to be operated in electrostatic feedback mode and enable ultra high resolution TEM imaging. The design and fabrication of the sensor is presented here. Preliminary measurements show that the fabrication has been successful.

Nyckelord: situ TEM, Nanoindentation, force sensor, capacitive detection, current measurement
