该论文提出了一种可扩展的多线圈能量共享无线功率接收网络，用于分布式体感皮层刺激的脑机接口。通过互联所有接收单元的功率输出，每个单元能以时分复用方式访问网络总功率，无需额外接收线圈，显著提升了效率和鲁棒性。
Abstract This work presents a system-level scalable wireless power receiver (RX) network for miniaturized distributed somatosensory cortex stimulation. By interconnecting the power outputs of all RX cells in the network, the stimulator in each cell can access the total received power of the whole network, with a time-division-multiplexing stimulation manner. Thus, each cell owns a multiple-input single-output wireless power RX network without additional RX coils, with improved efficiency and robustness. Brain-computer interfaces (BCIs) hold great promise for restoring motor and sensory function in individuals with severe limb disabilities. Recent advances have enabled intuitive somatosensory feedback, such as touch, vibration, and force sensations, from contact events in brain-controlled bionic limbs, significantly improving their usability and user acceptance [1, 2]. Delivering precise tactile feedback requires distributed micro-stimulation
