Electrochemical method is often chosen to analyze various bio-chemical reactions due to its operation simplicity with versatile applications. Thus, for this purpose, the procurement of potentiostat, an electrochemical-based analysis instrument, also needs to focus on the low price, but maintaining its rich analysis features. In this paper, we designed a low-cost and portable potentiostat system based on the ESP32 microcontroller. Even with the low-cost system design, it supports various electrochemical measurement methods, i.e. cyclic voltammetry (CV), linear sweep voltammetry (LSV), square wave voltammetry (SWV), differential pulse voltammetry (DPV), normal pulse voltammetry (NPV), and the observation of electrochemical current against time based on chronoamperometry measurement method. The potentiostat performance was assessed by the electrochemical signal accuracy and errors. Furthermore, the measurements can also be carried out semi-parallelly within three measurement channels simultaneously. The results showed that it could produce voltammograms with an average accuracy of more than 90%, compared to the commercial Emstat Pico. Even though having this comprehensive and extensive electrochemical analysis, the cost of the total system realization could be downsized to only USD 21.4.

“…This instrument plays a critical role by precisely controlling the applied voltage and capturing the electrical signals generated from redox reactions during analysis. While numerous reports detail laboratory-built potentiostats [48][49][50][51][52], they are typically designed specifically for EC measurements. Conversely, most PEC studies utilize expensive, multifunctional commercial potentiostats with separate, non-integrated excitation light sources.…”

Electrochemical and photoelectrochemical sensors are a rapidly developing field in analytical chemistry. However, commercial systems often lack versatility and affordability, hindering wider adoption. Additionally, the absence of integrated excitation light sources limits their application in photoelectrochemical sensing. Here, we present a highly precise, versatile, affordable measurement system for both electrochemical and photoelectrochemical sensing applications. The system incorporates a three-electrode potentiostat with a synchronized excitation light source. This design enables the system to perform conventional electrochemical measurements like cyclic voltammetry, chronoamperometry, and photoelectrochemical amperometric measurements with controlled light excitation. The developed measurement system operates within a voltage range suitable for a measurable current range of 1 nA to 18 mA, with a high precision of 99%. The excitation source is a monochromatic LED system offering seven distinct wavelengths with digitally controlled intensity via a digital-to-analog converter. Furthermore, an Android-based user interface allows wireless system control via Bluetooth Low Energy. The report also details the construction of a photoelectrochemical experiment using copper (II) oxide nanorods synthesized by the hydrothermal process as the photoactive material employed to test the experiment on a potassium ferricyanide/potassium ferrocyanide solution. This user-friendly system allows broader exploration of electrochemical and photoelectrochemical sensing applications.

“…To help students understand these interrelated and complex topics, electrochemical experiments in laboratory classes play a significant role since experiments can visualize the electrical effect(s) on a material of interest (e.g., Faradaic efficiency for the evolution of continuous bubbles of hydrogen gas from an electrode). On this basis, various groups have reported potentiostats, galvanostats, and/or electrochemical impedance spectrometers (EIS) as task-specific devices for their respective (educational) topics. − These structures of devices are generalized to a system consisting of three functionalities, a view, a controller, and core analog circuit(s), as depicted in Scheme , where the view represents a graphical user interface prepared by programming language(s), the analog circuit represents an electrical interface converting chemical response(s) from an electrochemical cell of interest to the form of electrical response(s), and the controller, which is typically a general-purpose microprocessor with peripheral task-specific integrated circuits, mediates between the view and analog circuit(s). The balance between functionality, capability, and cost of a device depends on how the three functionalities are purposefully configured.…”

“…The balance between functionality, capability, and cost of a device depends on how the three functionalities are purposefully configured. Accordingly, these reported devices are categorized into four classes: (1) wireless electrochemical detector as an IoT device; ,,,,,, (2) stand-alone device not requiring an external computer; ,,,,, (3) single-chip to miniaturize a device; ,,, and (4) electric-topologically multifunctional device as general-purpose equipment in a laboratory ,, (see the Supporting Information for the detailed classification of low-cost (<1000 USD) electrochemical devices reported previously).

A modern cybernetic potentiostat plays a significant role in realizing various electrochemical measurements. This technology report describes a general-purpose, scalable, handheld (10 cm2), yet affordable hardware–software framework for a potentiostat, galvanostat, and electrochemical impedance spectrometer with high capabilities: (1) cyclic voltammetry, square-wave voltammetry, and (potential-step) chronoamperometry as potentiostatic measurements conjugated with iR compensation and rotating-disk electrode apparatus in a wide range of current and voltage (pA to 0.1 A and ±12 V); (2) chronopotentiometry (with an arbitrary current) as a galvanostatic measurement (e.g., Karl Fischer titration); and (3) electrochemical impedance spectroscopy with a bandwidth of 0.1–1 MHz. Two additional devices derived from the framework were also demonstrated for fast potential scanning (up to 100 kV/s) and simple assembling, respectively. The presented framework provides rich teaching materials for chemistry, technology, engineering, and mathematics (e.g., STEM) education.
