Desarrollo de un microscopio electroquímico basado en servomecanismos

Abstract

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 microelectrochemical 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.
