植入式纳米发电机作为一种在体内采集生物力学能量的有前景的概念，最近得到了迅速发展。本文概述了植入式压电纳米发电机 (PENG) 和摩擦电纳米发电机 (TENG) 的最新进展，重点关注材料选择、工程和组装。讨论了 PENG 材料的演变，从 ZnO 纳米结构到高性能铁电钙钛矿，再到柔性压电聚合物介观结构。 TENG 的讨论重点是摩擦层的材料和表面特征、封装材料和设备集成。还讨论了这项有前途的技术所面临的挑战和未来可能的研究方向。 (C) 2017 年作者。
Implantable nanogenerators are rapidly advanced recently as a promising concept for harvesting biomechanical energy in vivo. This review article presents an overview of the most current progress of implantable piezoelectric nanogenerator (PENG) and triboelectric nanogenerator (TENG) with a focus on materials selection, engineering, and assembly. The evolution of the PENG materials is discussed from ZnO nanostructures, to high-performance ferroelectric perovskites, to flexible piezoelectric polymer mesostructures. Discussion of TENGs is focused on the materials and surface features of friction layers, encapsulation materials, and device integrations. Challenges faced by this promising technology and possible future research directions are also discussed. (C) 2017 Author(s).
