Summary: In this article, a physical approach is proposed to link the electrical parameters of a battery's equivalent circuit model (ECM) with the dimensions of its electrodes, contributing to the design of battery-powered systems. Through non-invasive measurements on three commercial coin cells of different sizes and capacities, dependency models are developed to accurately predict the ECM parameters based on electrode length. The proposed approach shows promising results in voltage simulations and predictions, making it a useful tool in developing customized batteries.

Summary: This research presents a systematic nonlinear analysis model for designing high performance ME devices, utilizing an equivalent circuit method based on complete magneto-mechanical coupling nonlinear magnetostrictive (MS) constitutive parameters for ME composites. The study demonstrates the effectiveness of the proposed method in predicting the response of ME composites and investigating the influences of key parameters such as prestress, bias magnetic field and length ratio on the ME response. The experimental results show that the proposed equivalent circuit model achieves a noise density of 6.08 nV/Hz and detection accuracy for AC and DC current better than 0.4 mA and 5 mA, respectively, providing a theoretical basis for optimal design of sensors and devices based on ME composites.

Summary: An architecture of an inductively powered passive transmitter for wireless sensor nodes is introduced in this paper. The transmitter is designed for inductively powered internally illuminated photoreactors. By integrating wireless sensors into the transmitter, a better understanding of the processes inside the photoreactors can be achieved. The passive electronics of the transmitter eliminate the need for batteries, allowing for continuous operation. Data transmission is implemented using the inductive layer in the low frequency range, with the data transmitting coil and energy receiving coil being implemented as the same coil for interference avoidance and weight and space saving. The transmitter operates in a two-step alternating cycle of energy harvesting and data transmission.

Summary: This paper investigated the impact of pavement material magnetization on resonant inductive coupling in wireless power transfer systems. The experiment revealed that the magnetization properties of pavement materials altered the active power and efficiency of the system. Adjusting component parameters and waterproofing between pavement layers can help mitigate the effects of magnetization and environmental factors on power transfer efficiency.

Summary: In this paper, a magnetically coupled resonant wireless power transfer system based on flexible printed circuit coils on a conformal cylindrical surface is designed. The relationship between the self-inductance/mutual inductance of the flexible coil and the bending radius of the conformal cylindrical surface is explored through mathematical analysis and simulations. The results show that as the bending radius decreases, the self-inductance and mutual inductance of the coil decrease nonlinearly. The transmission efficiency also decreases, and the resonant frequency shifts to a higher range.

Summary: By investigating the operation characteristics of a conformal coplanar four-coil magnetic resonant coupling wireless power transfer system under four different resonant states, it is found that operating under State 1, where compensated serial capacitance allows coils to work at the frequency of maximum Q-factor, shows the best transfer characteristic. The transmission coefficient can be maintained above 0.8 within a 30 cm transfer distance, indicating better power delivery to the load compared to other states.

Summary: In this article, a method for analyzing coupling mechanisms in radio frequency interference (RFI) problems is proposed. The partial element equivalent circuit (PEEC) method is used to derive the retarded inductances and capacitances between different mesh cells. With a novel partitioning algorithm, the capacitive and inductive coupling between arbitrary layout parts can be quantified based on the displacement current and induced voltage drop. The accuracy of the PEEC models is validated by comparison with different commercial tools. The proposed coupling mechanism analysis flow provides a useful prelayout tool for RFI risk analysis.
