2. Ashwini V., Dale R. An Inexpensive Field-Portable Programmable Potentiostat // Chem. Educator. – 2005. Vol.10. P. 1-6.

Abstract: The design and construction of a small, simple, rugged, inexpensive programmable potentiostat is presented. This experiment is intended for students in advanced analytical and integrated laboratory courses, in which students often study electronics and build instruments in order to better understand design, function, and optimization. It is also suitable for independent student projects in analytical instrumentation or electrochemistry, including projects involving field-portable electrochemical instrumentation. Advanced high school students interested in chemical instrumentation would find it within their ability as a special project provided they have a working knowledge of electronic circuits. This experiment requires students to use electronic devices and components, including op amps, to build a control circuit for electroanalytical experiments. The total cost of this potentiostat is less than $50 making it cost effective for individual or small-group experiments and special projects. Potentiostat dimensions are 3 cm × 13 cm on a printed circuit board. The simple circuit presented here is solid state, amenable to battery-powered operation, and if interfaced to an appropriate electrochemical cell, can be used as a rugged, field-portable electrochemical sensor system for monitoring environmental contaminants. Test results using potassium ferricyanide in cyclic voltammetric mode are presented to show the operation of the instrument. Linear correlation of anodic and cathodic peak heights with analyte concentration is demonstrated though a range of concentrations with a correlation factor of greater than 0.99.

3. Avdikosa E.M., Prodromidis M.I., Efstathiou C.E. Construction and analytical applications of a palm-sized microcontroller-based amperometric analyzer // Sensors and Actuators B. – 2005. Vol. 107. P. 372–378.

Abstract: The design and development of a palm-sized (9 cm×11 cm×3 cm), cost-effective, microcontroller-operated analyzer for direct amperometric measurements is described. The low-power-consumption electronics used allow 8 h of autonomous operation with a 9V battery (110 mAh), making thus this unit suitable for in-field measurements. Its operation is based mainly on the simple two-electrode potentiostatic mode, although the three-electrode mode is an option. The use of a microcontroller combined with analog and digital supporting circuits allows: (i) generation of the applied potential and the acquisition of analog signals with a gain auto-scaling capability; (ii) interaction with the operator for setting the measurement parameters; (iii) processing of data and displaying result on an LCD screen. Numerical data are automatically stored in memory and they can be retrieved by a personal computer through an RS232 port, either for creating measurements archives or for advanced processing. For this purpose, a program has been developed (on the LabVIEW platform) to provide a user-friendly graphical interface. The utility of this amperometric analyzer was assessed by performing experiments for the determination of ascorbic acid in standard solutions and pharmaceutical tablets.

Abstract: The design, construction, and characterization of a portable optocoupled
potentiostat are presented. The potentiostat is battery-powered, managed by a microcontroller, which implements cyclic voltammetry (CV) using suitable sensor electrodes. Its opto-coupling permits a wide range of current measurements, varying from mA to nA. Two software interfaces were developed to perform the CV measurement: a virtual instrument for a personal computer (PC) and a C-base interface for personal digital assistant (PDA). The potentiostat has been evaluated by detection of potassium ferrocyanide in KCl medium, both with macro and microelectrodes. There was good agreement between the instrumental results and those from commercial equipment.

6. Dobbelaere T.,Vereecken P.M., Detavernier C. A USB-controlled potentiostat/galvanostat for thin-film battery characterization // HardwareX. – 2017. Vol.2. P. 34-49.

Abstract: This article describes the design of a low-cost USB-controlled potentiostat/galvanostat which can measure or apply potentials in the range of ±8 V, and measure or apply currents ranging from nanoamps to max. ±25 mA. Precision is excellent thanks to the on-board 20-bit D/A-convertor and 22-bit A/D-convertors. The dual control modes and its wide potential range make it especially suitable for battery characterization. As an example use case, measurements are presented on a lithium-ion test cell using thin-film anatase TiO2 as the working electrode. A cross-platform Python program may be used to run electrochemical experiments within an easy-to-use graphical user interface. Designed with an open hardware philosophy and using open-source tools, all the details of the project (including the schematic, PCB design, microcontroller firmware, and host computer software) are freely available, making custom modifications of the design straightforward.

7. Meloni G.N. Building a Microcontroller Based Potentiostat: A Inexpensive and Versatile Platform for Teaching Electrochemistry and Instrumentation // J. Chem. Educ. – 2016. V.93. P. 1320−1322.

Abstract: A versatile potentiostat based on inexpensive and “off the shelf” components is reported. The platform was shown to be capable of performing simple electrochemistry experiments, suitable for undergraduate level teaching. The simple design and construction enable easy customization to accommodate a broad array of experimental designs. The equipment was used to calculate the diffusion coefficient of potassium ferricyanide in an aqueous solution, and the obtained result was in good agreement with the literature. Although simple in design, the low cost and good performance of the device make it a competitive alternative for teaching laboratories in the fields of both electronics and electrochemistry, and for developing teaching centers that cannot afford a commercial device.

8. Dryden M.D., Wheeler A.R. DStat: A Versatile, Open-Source Potentiostat for Electroanalysis and Integration // Plos one. – 2015. V.10. P.1-17.

Abstract: Most electroanalytical techniques require the precise control of the potentials in an electrochemical cell using a potentiostat. Commercial potentiostats function as “black boxes,” giving limited information about their circuitry and behaviour which can make development of new measurement techniques and integration with other instruments challenging. Recently, a number of lab-built potentiostats have emerged with various design goals including low manufacturing cost and field-portability, but notably lacking is an accessible potentiostat designed for general lab use, focusing on measurement quality combined with ease of use and versatility. To fill this gap, we introduce DStat (, an open-source, general-purpose potentiostat for use alone or integrated with other instruments. DStat offers picoampere current measurement capabilities, a compact USB-powered design, and user-friendly cross-platform software. DStat is easy and inexpensive to build, may be modified freely, and achieves good performance at low current levels not accessible to other lab-built instruments. In head-to-head tests, DStat’s voltammetric measurements are much more sensitive than those of “CheapStat” (a popular open-source potentiostat described previously), and are comparable to those of a compact commercial “black box” potentiostat. Likewise, in head-to-head tests, DStat’s potentiometric precision is similar to that of a commercial pH meter. Most importantly, the versatility of DStat was demonstrated through integration with the open-source DropBot digital microfluidics platform. In sum, we propose that DStat is a valuable contribution to the “open source” movement in analytical science, which is allowing users to adapt their tools to their experiments rather than alter their experiments to be compatible with their tools.

9. Muid A., Djamal M., Wirawan R. Development of a Low Cost Potentiostat Using ATXMEGA32 // AIP Conf. Proc. – 2014. Vol. 1589. P. 124-128.

Abstract: Potentiostat is principal devices in modern electrochemical research especially in the investigation of mechanism reaction which associated with the redox chemistry reaction and other chemical phenomena. Several applications measurement is developed based on this tool such as measurement of sample concentrations, quality test of food and medicine, environmental monitoring and biosensors or development of a protein sensor. We have developed a low cost, simple and portable potentiostat with a relatively small dimension. TLC2264 op-amp and ATMEGA32 microcontroller is used to build controller circuit system. Range potential measurement of this tool is between -1600mV and +1600mV within frequency range 1Hz - 1 kHz. The developed instrument has been tested for measuring samples using different voltammetry techniques, like cyclic, square wave, and linear sweep with relative error under 2.5%.

10. Kaur K. P., Lee S., Kim B. An Integrated Potentiostat // IDEC Journal of Integrated Circuits and Systems. – 2017. Vol. 3. No.3.

Abstract: This paper proposes an integrated potentiostat circuit to realize a compact, power-efficient, and cost-efficient biosensor driving circuit. The proposed potentiostat consists of two integrated operational amplifiers, each of which can be configured with negative feedback to perform potentiostat functionality. When configured as a potentiostat, the control operational amplifier controls the voltage of the counter electrode of the sensor to make the voltage difference between the reference and the working electrodes of the sensor to be identical to the input voltage fed by an external digital-to-analog converter. The other operational amplifier is configured as a transimpedance amplifier which converts the sensing current to the voltage, which is digitally converted by an external analog-to-digital converter. In the experiment, the proposed potentiostat is assembled with digital-to-analog converters, analog-to-digital converters, control-logics, and a laptop computer to form a portable and low-cost bio-sensor platform. With this platform enabled by our chip, users can easily and cost-efficiently generate the necessary control signals such as cyclic waves for bio-sensors.
