本文提出了一种新型的实验室，具有均匀的无线功率分布在3D，使长期的生物医学实验与小型自由移动的动物科目。所实现的功率传输室原型基于并联谐振器阵列和多线圈感应链路，以形成新颖且高效的无线功率传输系统。功率发射器单元包括几个相同的谐振器，这些谐振器被封装在重叠方形线圈的可扩展阵列中，这些线圈并联连接以提供沿着x和y的均匀功率分布。此外，所提出的腔室使用两个阵列的主谐振器，彼此面对，并并联连接，以实现均匀的功率分布沿着z轴。每个表面包括并联连接的9个重叠线圈，并实施为两层FR4印刷电路板。该腔室具有自然的功率定位机制，通过避免对主动检测和控制机制的需要，简化了其实施并简化了其操作。基于所提出的方法的单个功率表面可以提供69%的功率传输效率（PTE）和120 mW的功率传递到负载（PDL），对于4 cm的间隔距离，而完整的腔室原型在3D中提供59%的均匀PTE和100 mW的PDL，在尺寸为27×27×16 cm 3的腔室内的任何地方。
This paper presents a novel experimental chamber with uniform wireless power distribution in 3D for enabling long-term biomedical experiments with small freely moving animal subjects. The implemented power transmission chamber prototype is based on arrays of parallel resonators and multicoil inductive links, to form a novel and highly efficient wireless power transmission system. The power transmitter unit includes several identical resonators enclosed in a scalable array of overlapping square coils which are connected in parallel to provide uniform power distribution along x and y. Moreover, the proposed chamber uses two arrays of primary resonators, facing each other, and connected in parallel to achieve uniform power distribution along the z axis. Each surface includes 9 overlapped coils connected in parallel and implemented into two layers of FR4 printed circuit board. The chamber features a natural power localization mechanism, which simplifies its implementation and ease its operation by avoiding the need for active detection and control mechanisms. A single power surface based on the proposed approach can provide a power transfer efficiency (PTE) of 69% and a power delivered to the load (PDL) of 120 mW, for a separation distance of 4 cm, whereas the complete chamber prototype provides a uniform PTE of 59% and a PDL of 100 mW in 3D, everywhere inside the chamber with a size of 27×27×16 cm3.
