该论文提出了一种128通道、2mm×2mm的无电池神经芯片，通过多载波反向散射通信实现同时多通道传输，解决了传统有线神经接口的尺寸和供电限制。芯片采用无线能量传输和天线共享技术，实现了微型化、电池无源的神经记录植入体。
wireless implants have been investigated as an alternative to traditional cable-based neural interfaces. Simultaneous massive-channel recording capability is essential to study cellular interconnections and network properties that arise from synchronized cellular activity. Meanwhile, the battery-free techniques based on wireless power transfer (WPT) and backscatter communication help to miniaturize the neural-recording implant by battery eliminating and antenna sharing [1]. To merge a large number of channels into a single battery-free chip, there are two conventional topologies (Fig. 31.4.1, left): 1) The wireless system used multiple analog front-ends (AFEs) for signal acquisition and merges the signals before a single analog-to-digital converter (ADC) [2-4]. Even with shared ADC
