GUILLEN RODRIGUEZ, J. et al. Desarrollo de un microscopio electroquímico basado en servomecanismos. Rev. mex. fis. [online]. 2013, vol.59, n.3, pp.208-216. ISSN 0035-001X.

An electrochemical microscope was developed using novel instrumentation based on a nanopositioning stage (containing servomotors) and controlled through a motion controller card. Even though a movement specialized hardware offers advantages doing scanning microelectro-chemical experimentation, it has not been previously reported. The whole system was controlled through a personal computer using a data acquisition card and the serial RS232 port. The complete software for controlling the system was developed and tested through typical scanning electrochemical microscopy experiments. As a result, approach curves, chemical maps, morphology and interpolated movements over dielectric and conductor samples using the constant height technique, were obtained.
