The ultimate application of bio-integrated, stretchable electronics hinges on the indispensable modules of stretchable wireless data transmission and power supplies. While radiofrequency (RF) antennas and rectennas could enable wireless communication and RF energy harvesting in the far-field, their performance deteriorates because of the frequency detuning from mechanical deformations. Here, stretchable wideband antennas and rectennas are introduced to robustly operate and combine received RF power over their wideband upon mechanical deformations. Devices with stretchable wideband antennas and rectennas create application opportunities such as self-powered systems, remote monitoring of the environment, and clean energy. A comprehensive set of manufacturing schemes, device components, and theoretical design tools for the stretchable wideband antennas and rectennas is reported. A stretchable wideband rectenna integrated with various functional sensing modules and its demonstration with enhanced effective rectenna efficiency over the state-of-the-art by 10-100 times illustrates a system-level example of this technology.
生物集成可拉伸电子器件的最终应用取决于可拉伸无线数据传输和电源这些不可或缺的模块。虽然射频（RF）天线和整流天线能够在远场实现无线通信和射频能量收集，但由于机械变形导致的频率失谐，它们的性能会下降。在此，引入了可拉伸宽带天线和整流天线，以便在机械变形时能在其宽带上稳健运行并组合接收的射频功率。具备可拉伸宽带天线和整流天线的器件创造了诸如自供电系统、环境远程监测和清洁能源等应用机会。报道了一套针对可拉伸宽带天线和整流天线的全面制造方案、器件组件和理论设计工具。一个集成了各种功能传感模块的可拉伸宽带整流天线，以及其有效整流天线效率比现有技术提高10至100倍的演示，说明了该技术的一个系统级实例。
