“…EIT system uses various methods of electrode arrangement like one ring or more than one ring according to the application [7], but in this work, we used one ring of the electrodes with nail type electrodes. The electrodes may be used nail type, and Ag-Agcl electrode is also used for biomonitoring and ECG, EEG and other application of medical monitoring [12]. The placement of these electrodes on the body, we need some leads, these leads are directly attached to the electrode of the body sites and used to examine electrical movement by monitoring change between them [6].…”

This paper discussed the Design and implementation of the electrical impedance-based system, which covers both techniques (Impedance Plethysmography (IPG) and Electrical Impedance Tomography (EIT)). The electrical impedance distribution image of the cross-section of a phantom based on current excitation and voltage measurement using electrodes pair is reconstructs image according to the electrical property of the medical phantom. The electrical impedance based image provides the significant morphological information. Image quality depends upon many other iterative process and image processing algorithms in addition to. The hardware designing of the system is a most important part of all impedance-based techniques. In measurement section, the current source of the electrical impedancebased system should supply multi-frequency signal for measurement because it provides more useful information about the phantom. Therefore, a signal source that provides accurate excitation and a reference signal for measurement is more useful. Matlab is used for image reconstruction and processing of the impedance data.

“…In this context, a microcontroller based simple, low cost, lightweight prototype instrumentation impedance measuring device has been designed and developed for bioimpedance measurement and tested and evaluated with the fruit samples. The previous works (Anand, Amit, Ruhi, & Pahuja, 2010;Sagar & Quazi, 2012;Hoja & Lentka, 2009;Puchalski & Brusewitz, 1999;Radil, Pedro, & Cruz Sera, 2005;Hakan et al, 2009;Amer Atta, 2014;Zhang, 2007) are generally found with AD5933 (Analog Devices, Inc.) (Data Sheet, AD 5933, Analog Devices) based impedance converter measuring the complex bioelectrical impedance. Some of the previous works are also developed to use expensive gain-phase detectors like AD8302 (Analog Devices, Inc.) (Data Sheet, AD 5930, Analog Devices).…”

Electrical impedance spectroscopy (EIS) is an electrical impedance technique to characterize the fruits and vegetables in terms of their frequency dependent bioimpedance profile. Standalone, portable, and low‐cost instrumentation is always preferred for conducting EIS procedures. This article reports the studies on the design and development of a Microcontroller based portable impedance measurement system to conduct the EIS studies on the fruits during ripening and storage. The proposed laboratory based EIS system is developed with a Microcontroller ATmega16, a Direct Digital Synthesizers based constant current source AD5930, a current to voltage converter, a low pass filter, and a DSO. To test and evaluate the developed system, the cucumber impedance is studied under the storage condition using EIS to characterize the cucumber freshness from the electrical impedance data. The real parts, imaginary parts of the cucumber impedance are calculated and the Nyquist diagrams are analyzed to study the equivalent circuit analysis. The developed system is compared with a standard impedance analyzer and it is observed that the results obtained from the developed system closely match with the data measured by the commercial impedance analyzer. The developed system is also found suitable for EIS studies of fruits, vegetables, and other biological tissues. The developed system is found low‐cost, fast, and user friendly. PCB based version of the proposed system with display unit will be found as a portable, standalone, and EIS system suitable for outdoor measurement in agricultural‐field applications. Practical applications Microcontroller based low cost electrical impedance spectroscopy (EIS) has been developed and is studied for EIS based fruit ripening analysis. The system is compared with the standard commercial impedance analyzer and it is found suitable fruit ripening characterization, vegetable freshness detection, and health studies of other biological tissues. The microcontroller based EIS system is found portable, low cost, fast, and user friendly device which can be used in laboratory, cultivation fields, cold storages and shops and markets. The developed system allows nontechnical person to operated and collect the data from fruit and vegetable samples. The system acquired data significantly correlate the bioimpedance variation with the ripening states which can be potentially utilized to study the fruit ripening noninvasively at low cost. Hence the product‐form of the developed devise could even be operated by field persons, farmers, and other common men to evaluate the fruit ripening and vegetable freshness.
