“…) [10],the equivalent of the resonant inductor and capacitance values change, thus changing the resonant frequency see Figure 1 In this paper, the PCB coil material is copper, PCB board material is FR4_epoxy, Table 1 shows all the electrical parameters. In Figure 2, the length and width of the coil and the distance between the coil and the coil are shown,and the physical parameters of the coil are represented by the following symbols: L is the length of the coil, W represents the width of copper, S represents the distance between adjacent coils margin line , h_c represents copper thickness (In this paper, the thickness of copper is all 0.035mm), h_f represents the thickness of the substrate FR4_epoxy (In this paper, the thickness of PCB plate is all 0.33mm), N represents the total number of turns of the coil.…”

Abstract. With the development of science and technology, the application of implantable biomedical electronic devices which play an important role in biological research and medical diagnostics becomes increasingly popular [1]. Nowadays wireless energy transfer is one of the most popular research field, it can penetrate the skin to supply electric energy to implantable biomedical electronic devices steady, so it is more and more used in the biomedical field. The main constraints restrict for wireless charging technology to realize miniaturization and portability is that the volume of the transmission coil is difficult to reduce. The production process of the PCB(printed circuit board) coil is simple, and its width, thickness, line spacing and other parameters can be precisely controlled, mass production of PCB coils have same parameters, meanwhile ,PCB coil is easy to integrate with external circuit. In order to improve the efficiency of the radio transmission system fundamentally, by comparing the test methods, we study the PCB coil width and wire spacing, analyze the impact of these two factors on the resonant frequency. And we reach the following conclusion: The resonant frequency is negative correlated to the number of turns when the wire spacing is fixed. When the number of turns is constant, the wire spacing of the coil and the resonant frequency are positively correlated.

“…This paper introduces the method of reducing the skin effect by using the Liz line or the silver plated wire [9]. The Liz line can make the electric current and electromagnetic field distribute evenly, the surface resistance of the silver plated wire is small, and the skin depth is small [10]. The structure of the coil includes the wire diameter and the electrical conductivity, the diameter of the coil, and the winding way.…”

Abstract. With the development of science and technology, the application of implantable biomedical electronic devices which play an important role in biological research and medical diagnostics becomes increasingly popular [1]. For the implantable electronic equipments, long-term, stable and secure power supply are critical issues. Nowadays wireless energy transfer is one of the most popular research field, it can penetrate the skin to supply electric energy to implantable biomedical electronic devices steady, so it is more and more used in the biomedical field.The main constraints restrict for wireless charging technology to realize miniaturization and portability is that the volume of the transmission coil is difficult to reduce. The production process of the PCB(printed circuit board) coil is simple, and its width, thickness, line spacing and other parameters can be precisely controlled, mass production of PCB coils have same parameters, meanwhile PCB coil is easy to integrate with external circuit. Compared with the solenoid coil, PCB coil has smaller volume andhigher power density, so it has been widely used in magnetic resonance wireless power transmission field.In order to improve the efficiency of the radio transmission system fundamentally, by comparing the test methods, we study the PCB coil width and wire spacing, analyze the impact of these two factors on the resonant frequency. And we reach the following conclusion: The resonant frequency is positive correlated to the width of the coil when the wire spacing is fixed. When the coil width is constant, the wire spacing of the coil and the resonant frequency are positively correlated.This template explains and demonstrates how to prepare your camera-ready paper for Trans Tech Publications.

“…For the development of the current transducer, the Rogowski coil has been chosen because of the good performance and low-cost that this typology of transducer can guarantee [11][12][13][14][15][16][17][18]. A poly-V transmission belt (Figs.1-2) has been adopted as the core for the winding; it allows sizes similar to some commercial sensors, a rectangular section, good flexibility and dimensions that are not influenced by temperature variations; moreover, no magnetic materials are included in the belt.…”

In this manuscript, a low-cost power transducer, suitable for the implementation of electrical power meter, is presented. The current sensing unit is based on a Rogowski coil, while the voltage transduction is performed with an active voltage divider. An analog multiplier is adopted to generate the instantaneous power waveform. Active power and apparent power are measured with a digital multimeter. Each element of the proposed transducer has been experimentally characterized by means of reference instrumentation, and the results reported and discussed.
