“…Due to good flexibility and high reliability, wireless sensor network (WSN) nodes have been widely used in infrastructure health monitoring, smart grid online measurement system, building automation, biomedicine, and other fields. [1][2][3][4][5] Batteries with limited service life and regular maintenance requirement, have become a bottleneck during the applications of WSN in the past few decades. Various energy sources exist in the surrounding environment, such like solar, wind, thermal, and vibration energy, et al Harvesting such kind energy with suitable methods should be an alternative to the battery as the power supply for WSN nodes.…”

In recent years, energy harvesting technology has become a promising power supply method for low-power wireless sensor nodes. According to the application requirements of energy acquisition, a piezoelectric and electrostatic hybrid vibration energy harvester is proposed in this paper. Compared with other vibration energy harvesters, the proposed hybrid harvester is easier to miniaturize and integrate into a Micro-Electro-Mechanical System (MEMS). The electromechanical coupling model of the hybrid harvester is established. The optimal design of the proposed harvester is carried out based on numerical simulation. The optimal matching impedance of piezoelectric and electrostatic modules are calculated based on numerical simulation and validated through experiments, which are 80-90 kΩ and 15-20 MΩ, respectively. The output power of the hybrid vibration energy harvester is increased by 0.04%, 0.08%, 0.102%, and 0.097%, when the excitation acceleration is 0.1 g, 0.15 g, 0.2 g, and 0.25 g, respectively, compared with the single piezoelectric module.

“…Complexity of CDMA technology necessitates specialised knowledge and apparatus, which can increase implementation expenses. CDMA-based systems also necessitate precise calibration and maintenance to ensure precise data transmission and measurement [10,[14][15][16]. In MC-OFDM, data is transmitted over multiple parallel subcarriers that are closely spaced in frequency.…”

The paper focuses on improving wireless communication networks for nuclear radiation monitoring by analyzing and evaluating the performance of Multi Carrier Code Division Multiple Access (MC-CDMA) as a wireless communication system. The work aims to determine the outage probability as a quality-of-service parameter and investigate the average channel capacity under channel deterioration. They use closed form expressions to present the performances of these characteristics and study the impact of the number of branches and subcarriers on the outage probability. In addition, the authors propose a robust and reliable approach to channel under fading and study the capacity of MC-CDMA with the largest number of users. The results obtained from the study confirm that exponential channel fading achieves the lowest outage probability compared to other channel degradations. Moreover, the proposed results guarantee high average channel capacity and high throughput, which are essential for the successful deployment of MC-CDMA systems. The findings of this study provide valuable information for researchers and engineers working in the field of wireless communication systems, particularly those interested in the design and optimization of MC-CDMA systems. Overall, the paper contributes to the understanding of the performance of MC-CDMA systems under various channel conditions and provides insights into the design and optimization of such systems. The results show that the importance of utilizing robust and reliable wireless communication systems in nuclear radiation monitoring to ensure the accuracy and reliability of the data obtained.
