Small variations of signals obtained by electrochemical test, was studied by
digital signal processing techniques. Electrochemical noise and electrochemical
curves of polarization was very useful to obtained electrochemical behavior of
alloys, but the low signal levels of measurements obtained show that some of
the information was unmeasurable and unidentified. Graphene oxides (GO)
samples, were alloy by ball milling procedure adding Lithium. Matlab , ImageJ
and SIGVIEW software were used for Digital Signal studies. Comparing the
signals obtained by electrochemical techniques and the research by
computational tools was possible to find a path of behavior of samples. Display
Devices made by graphene needs find in to the deep of the structure of samples
and improve in nanotechnology area. Maintain electrochemical stability was the
aim in this study, different deformations as twisting and bending are very
important in portable electronics devices.
