Electrochemical Impedance Spectroscopy System Based on a Teensy Board

New UV‐Curable Anticorrosion Coatings from Vegetable Oils

“…Impedance data were further analysed using equivalent electrical circuit modelling in order to derive a model for the interaction between the metal-coating system and the environment. [36] Actually, this processing enables to derive a model for the investigated physical system using conventional electrical components and thus allows to study the evolution of the different elements of the system as a function of the immersion time. Two electrical circuits have been used, which are typically employed to model coatings impedance; [37,38] they are represented in Figure 1.…”

Field deployable impedance-based corrosion sensor

“…For accuracy, the system can measure the impedance of 50 k while maintaining an error within 5%. The system is dedicated to the electrochemical cells with three electrodes 18 . Besides the impedance measurement systems reported in the literature, many commercialized devices can perform EIS analysis in a wide range of applications.…”

Degradation Observations of Protective Coatings: An Improved Version of Coating Impedance Detector

“…As an alternative to the well-known traditional testing methods (e.g., the salt spray test [1] and QUV accelerated weathering test [2]), in recent years, many studies have investigated nondestructive testing (NDT) and strategies for evaluating the properties of a coating-specifically, acoustic emission [3], ultrasonic [4], eddy current [5][6][7], infrared thermography [8][9][10], optical [11][12][13][14], electrical [15][16], and electrochemical testing [17][18][19][20][21][22][23][24][25][26][27][28][29] methods. All these methods have their own advantages, however, each of them also has its particular limitations.…”

“…The disadvantages of EIS include its high cost; bulky hardware; and requirement of a low-disturbance environment, steady power supply, and other additional equipment; these disadvantages limit its usability for in situ measurements. As a result, many researchers have aimed to simplify the EIS experimental setup and accordingly proposed simplified EISbased monitoring systems [18][19][20][21][22][23][24][25][26][27][28][29]. For example, Sebar et al recently formulated a portable low-cost device for performing EIS measurements [29].…”
