该论文提出了一种毫米级无电池生物传感与刺激植入体，采用磁电功率传输技术实现安全无线供电，并利用0.9pJ/b的超低功耗PWM反向散射进行数据通信，解决了传统植入体体积大、需要电池以及无线供电效率低的问题。
Joshua Woods, Wei Wang, Jacob T. Robinson, Kaiyuan Yang Rice University, Houston, TX *Equally Credited Authors (ECAs) Bioelectronic implants transform clinical therapies by offering unprecedented tools for precise sensing and intervention inside the human body. Wireless, battery-free, and miniaturized (mm-scale) bio-implants are highly desirable to enhance safety, simplify surgery, minimize behavioral disruptions, and boost long-term stability over conventional bulky implants [1-3]. Developing such devices faces two crucial challenges: safe and reliable wireless power transfer (WPT) and efficient bidirectional telemetry. Magnetoelectric (ME) WPT, which converts low-frequency magnetic fields to electrical energy via acoustic coupling (Fig. 33.6.1, top), is an emerging WPT modality specialized for mm-sized implants. It offers strong penetration through various mediums without absorption or reflection issues, leading to superior WPT efficiency, power level under
