OROZCO-VASQUEZ, Juan Carlos et al. Design and construction capacitive electric field equipment for cell stimulation. Rev.EIA.Esc.Ing.Antioq [online]. 2020, vol.17, n.34, pp.338-348.  Epub 07-Set-2021. ISSN 1794-1237.  https://doi.org/10.24050/reia.v17i34.1410.

The searching of options for cancer treatments at low cost, less invasive and with minor side effects is still an interest matter. The study of a combined system of low voltages electric fields with nanomaterials, the latter working as nanovectors, in the cancer treatment has shown promising results. This work presents the design, simulation and construction of an electrical stimulator equipment capacitive type of low voltage for stimulation of healthy skin cells and melanoma type combined with gold nanoparticles. The equipment allows to modify voltage, frequency, current intensity, waveform and duty cycle. The design was performed in Arduino DUE platform, then taken to Eagle to the PCB development and the visualization on a LCD screen. The implemented generator is finally connected to a couple of parallel plates which are in charge of the induced electric field. From the variables delivered by the equipment, accuracies lower than 1.5% were found, this guarantees the technical fulfillment of the equipment in the needed variables.
