Supercapacitor Portable System for Automatic Acquire of Electrical Signals, Characterization and Electrical Schematic Modeling for Microelectronic Device Application

In this paper, new functionalities are presented for the Portable System for Automatic Acquire of Electrical Signals for Supercapacitor Characterization (SAAES^SC) [1]. These supercapacitors can be used in low consumption electro-electronic devices, energy harvesting and Internet of Things (IoT) applications [2] [3] [4]. In addition to self-discharge test of supercapacitors, functions for testing galvanostatic charge and discharge cycling, automatic extraction of electrical parameters, supercapacitors circuit models and definition of test methodology were implemented. To validate the SAAES^SC, it is used two supercapacitors to obtain measurements with both SAAES^SC and VMP3 Multichannel Potentiostat from BioLogic [5]. Those measurements were compared, showing a mean percentage error of 0,23%.
