Abstract :
We have developed a compact and easy-to-use MEMS (micro electro-mechanical) calibration device for atomic force microscopy, using a method that allows traceability to the SI system. The new device, which we call an electrical nanobalance, is calibrated by a non-contact method, a combination of electrical measurements and Doppler velocimetry. For the AFM user, the device offers a simple, accurate and traceable method for AFM cantilever spring constant calibration, for the first time
