Abstract

Implantable medical devices (IMDs), like pacemakers regulating heart rhythm or deep brain stimulators treating neurological disorders, revolutionize healthcare. However, limited battery life necessitates frequent surgeries for replacements. Ultrasound power transfer (UPT) emerges as a promising solution for sustainable IMD operation. Current research prioritizes implantable materials, with less emphasis on sound field analysis and maximizing energy transfer during wireless power delivery. This review addresses this gap. A comprehensive analysis of UPT technology, examining cutting-edge system designs, particularly in power supply and efficiency is provided. The review critically examines existing efficiency models, summarizing the key parameters influencing energy transmission in UPT systems. For the first time, an energy flow diagram of a general UPT system is proposed to offer insights into the overall functioning. Additionally, the review explores the development stages of UPT technology, showcasing representative designs and applications. The remaining challenges, future directions, and exciting opportunities associated with UPT are discussed. By highlighting the importance of sustainable IMDs with advanced functions like biosensing and closed-loop drug delivery, as well as UPT's potential, this review aims to inspire further research and advancements in this promising field.

增强超声波功率传输：效率、声学和未来方向。

植入式医疗设备（IMDs），如调节心律的心脏起搏器或治疗神经系统疾病的脑深部刺激器，给医疗保健带来了革命性的变化。然而，由于电池寿命有限，必须频繁进行手术更换。超声功率传输（UPT）是实现 IMD 可持续运行的一个前景广阔的解决方案。目前的研究以植入材料为重点，对声场分析和在无线功率传输过程中最大化能量传输的重视程度较低。本综述就是针对这一空白展开的。本综述全面分析了 UPT 技术，考察了最先进的系统设计，尤其是在供电和效率方面。综述严格审查了现有的效率模型，总结了影响 UPT 系统能量传输的关键参数。首次提出了一般 UPT 系统的能量流图，以便深入了解其整体功能。此外，综述还探讨了 UPT 技术的发展阶段，展示了具有代表性的设计和应用。此外，还讨论了与 UPT 相关的其余挑战、未来方向和令人兴奋的机遇。通过强调具有生物传感和闭环给药等先进功能的可持续 IMD 的重要性以及 UPT 的潜力，本综述旨在激励在这一前景广阔的领域开展进一步的研究和进步。
