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 efficiency over the state-of-the-art by 10–100 times illustrates a system-level example of this technology.

生物集成、可伸缩电子产品的最终应用取决于可伸缩无线数据传输和电源等不可或缺的模块。虽然射频 (RF) 天线和整流天线可以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频率失谐，它们的性能会下降。在这里，引入了可拉伸的宽带天线和整流天线，以便在机械变形时在其宽带上稳健地操作和组合接收到的射频功率。具有可伸缩宽带天线和整流天线的设备创造了应用机会，例如自供电系统、环境远程监控和清洁能源。一整套制造方案、设备组件、报告了可伸缩宽带天线和整流天线的理论设计工具。与各种功能传感模块集成的可伸缩宽带整流天线及其演示，其有效效率比现有技术提高了 10-100 倍，说明了该技术的系统级示例。
