Wireless power transmission (WPT) is vitally important for portable electronics. Recently, wireless energy delivery via Maxwell displacement current from triboelectric nanogenerator may open new routes to develop novel technologies especially for implantable medical devices and sensor network due to its flexibility, adaption, convenience and safety. In this paper, the propagation characteristics of WPT are explored, which are based on displacement current from a spherical high frequency electric field. The results showed that the spherical surfaces with the same radius from the center have equal value of electric field intensity. When the receiver has a larger area or workload, the output has a higher value, which is subject to the electric field intensity. However, the current is almost unchanged with increasing output power below 15 kΩ of load resistance in series, which may have potential applications for sensors. Furthermore, the receiver circuit of wireless energy is in accordance with the traditional serial and parallel circuit regularity. Based on these, we are going to assume that the electric field source is a reservoir, and water flow is analogous to current. The assumption is suitable for studying propagation characteristics. This new discovery may also offer a new research direction for WPT based on Maxwell displacement electric field.

无线电源传输（WPT）对于便携式电子设备至关重要。最近，由于其灵活性，适应性，便利性和安全性，通过摩擦电纳米发生器通过麦克斯韦位移电流进行的无线能量传输可能为开发新技术开辟新途径，尤其是针对可植入医疗设备和传感器网络的新技术。在本文中，基于来自球形高频电场的位移电流，探讨了WPT的传播特性。结果表明，距中心半径相同的球面具有相等的电场强度值。当接收器的面积较大或工作量较大时，输出具有较高的值，该值受电场强度的影响。然而，当输出功率低于15kΩ串联负载时，电流几乎不变，这可能对传感器有潜在的应用。此外，无线能量的接收器电路符合传统的串行和并行电路规则。基于这些，我们将假设电场源是一个蓄水池，并且水流类似于电流。该假设适合于研究传播特性。这一新发现也可能为基于Maxwell位移电场的WPT提供新的研究方向。我们将假设电场源是一个蓄水池，并且水流类似于电流。该假设适合于研究传播特性。这一新发现也可能为基于Maxwell位移电场的WPT提供新的研究方向。我们将假设电场源是一个蓄水池，并且水流类似于电流。该假设适合于研究传播特性。这一新发现也可能为基于Maxwell位移电场的WPT提供新的研究方向。
