We were pleased to introduce that 2021 8th International Conference on Electronics Engineering and Technology (ICEET 2021) was successfully held during July 16-18, 2021 in full virtual style.

Considering the COVID-19 pandemic and the severe travel restrictions worldwide, after careful consideration and following some participants' advices, the organizing committees decided to convert ICEET 2021 into a fully virtual conference. It has been a very difficult decision, but it has also given to all of us an opportunity to innovate and to test a new style of conference in a safer and convenient way in this special period. The primary goal of the conference is to promote international academic exchange and international cooperation, and provides an opportunity for researchers around the world to exchange ideas and latest research results, in both theory and application of Electronics Engineering and Technology. The conference will be held every year to make it an ideal platform for people to share views and experiences in Electronics Engineering and Technology and related areas.

Electrorheological (ER) fluid, as a non-homogeneous smart material, has been studied and applied extensively in various fields. This paper develops a dynamics model to describe the changes of the ER system's pseudo phase change, from thermal-dominant to electric-dominant aspect. ER fluid's material properties can be changed and controlled effectively in response to an external electric field, while under an electric field over a certain threshold, the ER system experiences a pseudo phase change from liquid to solid. This paper shows the advantages of the ER fluid in mechanical engineering, specifically in friction brakes and Anti-lock Braking System (ABS), over conventional friction brakes. The ER brakes demonstrates higher endurance, service life and control system compatibility, especially when applied to to optimize vehicle safety during an emergency. The result of this paper shows a promising future for the ER materials in industrial brakes for its controllable mechanical properties.

All sub-blocks in the same layer use the same sampling rate, which leads to a deviation between the sampling and observation information in the multi-scale block compression sensing algorithm and the original image information, and results in reducing the accuracy of image reconstruction. Therefore a multi-scale block compression sensing algorithm (HEI) is proposed to reduce the deviation of information. Image blocks are decomposed to obtain multi-scale blocks in this method. And the high frequency coefficients of wavelet transform are used to extract the edge information, which is used as the adaptive sampling rate of sub-blocks. Experiments are carried out on 6 standard images, and the effects of different hierarchies of wavelet transform and the scale of graph subblocks on HEI method are analyzed. The experimental results show that, compared with the adaptive sampling method using low frequency information, the proposed method has better quality and visual effect on the reconstructed images of the test images.

This paper presents a human body temperature monitoring system in which the temperature read by the sensor is analyzed by the programmed logic from a microcontroller. Two LEDs are used to signal out the patient's body temperature. The whole system is powered by button cell type supercapacitors which are charged by a mini photovoltaic panel. This system is designed and addressed to people who want or need to continuously monitor their body temperature. It is a compact and easy to use system, being integrated in a bracelet that is attached to the upper arm. The successful functioning of the designed power supply opens new directions in the on-body sensor field, where the replacement of the classical batteries can be avoided by the patient.

The performance design of SRAM type FPGA single particle has been interrupted by its logical function failure, resulting in damage to its normal storage function and storage data. This research carries out the experimental design and discusses its feasibility based on the SRAM type FPGA single particle effect research to better improve the storage unit structure and capacity.

Commercial equipment provides phase noise measurement solution for voltage-controlled oscillator (VCO), but it also needs to connect additional tuning voltage for VCO frequency stabilization. If the frequency-drifting VCO cannot be tuned directly, the measurement would be difficult. In this article, we present a prototype of a phase noise measurement system, without any connection for frequency stabilization. The innovation of this work is to compensate the frequency drift by introducing a delayed path. The frequency drift of the signal under test is calculated in advance, and then accurately compensates the delayed signal. The results are compared with commercial equipment, and it shows better performance when measuring frequency-drifting signal directly.

The work is devoted to the development and research of an algorithm for identifying transients in order to monitor the performance of Peltier thermoelectric modules (TEMs). The paper presents the main expressions for the analysis of heat transfer in TEM, as well as a block diagram of the algorithm for identifying the performance of TEM based on the comparison between the time constants of the tested and the reference module according to the Student's criterion. The proposed method was tested experimentally by comparing the time constants of the correct and defective modules 1MS06-030-05. The experiment showed a significant difference between the duration of the transition process of the correct module (0.7 s) and defective module (0.4 s) with a mean square error of 0.07 s and a significance level of <0.001. In the future, it is planned to develop software based on this algorithm, as well as examine the proposed method by testing a wide class of TEMs.

Communication systems of the solar-blind ultraviolet range UV-C from 200 to 280 nm provide the possibility of communication in the absence of line of sight due to the strong scattering of UV radiation in the atmosphere. For the effective use of UV-C communication systems, an adequate assessment of the energy budget of the UV channel is necessary. Analytical expressions are obtained that characterize the energy reserve of the UV-C system in relation to the specified characteristics of the optical receiver, transmitter, and UV channel. Based on the analytical and numerical model of losses in the UV channel, the energy reserve of the UV-C communication system is modeled on the distance between the transmitter and receiver, the elevation angles and the azimuthal deviation of the transmitter and receiver. The results obtained can be used to calculate and optimize ad-hoc communication networks with UV-C channel, characterized by changes in the spatial location of network nodes during operation.

In the unknown water environment, unmanned ships' perception of unknown water environment, map construction, and identification and ranging of obstacles have become research hotspots in the field of water environment perception. The visual SLAM (simultaneous localization and mapping) scheme is used to obtain the unmanned ship's navigational waters to obtain the unknown waters environment. The mathematical model is established based on the feature points extracted by the ORB-SLAM2 algorithm, that is, the feature point coordinates are extracted to establish a coordinate system, and the lowest point coordinates are used as the starting point to assume the shoreline, and the shoreline After the upper and lower feature points are partitioned, the feature points in the area above the shoreline are curve-fitted, and then the reflection curve is obtained according to the reflection principle, and finally the variance calculation is performed on the points in the reflection curve and the points in the area below the shoreline. When the variance is the smallest value or Get the shoreline position when it is zero. The results show that the method can accurately identify the location of the shoreline and lay the foundation for the unmanned ship to realize surface target recognition.

Calcium and zinc are two essential metal ions that have important roles in cellular mechanisms. They participate together in regulating intracellular transport, and zinc-dependent calcium release had also been observed in cells. Thus, a method for detecting those two ions simultaneously while not interrupting cellular processes (In vivo) is in great need and importance. In this paper, we propose a probable research direction of utilizing two distinct RNA cleaving DNAzymes, wavelength-controlled photocaging groups and AuNP or GO carriers to develop a probe that enables simultaneous detection of Ca2+ and Zn2+ ions in vivo and in vitro. The probe is proposed to have two types of DNAzymes, each separately sensitive to Ca2+ and Zn2+ and marked with two distinct fluorophores (FAM and Cy5) and quenchers (BHQ 1 and 2). The DNAzymes are also photocaged with different wavelengths and mounted on carrier AuNPs or GO. Under presence of Ca2+ and Zn2+ ions, the substrate is then cleaved which unquenched the fluorophores and produces a fluorescent signal. The feasibility and possible obstacles and improvements of this method are also discussed in the paper; the practicable applications of this study in bioengineering and clinical measurement technology are indicated. This proposed method could be a powerful tool in exploring the correlation between Ca2+ and Zn2+ ions in cells and better understand the functions of such ions.
