PFI-AIR: Nanoplasmonic Metamaterial Antennae for Efficient Wireless Power Transmission

美国国家科学基金会加速创新研究（AIR）项目将包含大量的国家努力，将纳米光子和纳米等离子体研究发现转化为生物传感应用的创新产品。实现这些生物传感器的一个挑战涉及到为目标生物反馈提供动力驱动这些传感器的方法。这个AIR项目建议使用纳米等离子体超材料方法来建模和演示一个紧凑的定向能量收集系统，该系统依赖于亚波长尺度的阵列结构来产生整流天线或整流天线。原型系统有望将关键的无线传输指标——比功率密度——提高至少一个数量级，达到~0.1 W/g。如果成功，这个AIR项目的成果将彻底改变便携式传感器和设备的电力输送，并改变植入式生物传感器的设计空间，用于测量和控制体内的生物功能。

This NSF Accelerating Innovation Research (AIR) project will comprise a substantial national effort to translate nanophotonic and nanoplasmonic research discoveries into innovative products in biosensing applications. A challenge for the implementation of these biosensors relates to methods of delivering power to drive those sensors for the targeted bio-feedback. This AIR project proposes to use nanoplasmonic metamaterial methods to model and demonstrate a compact directional power harvesting system that relies on subwavelength-scale arrayed structures to yield a rectifying antenna or rectenna. A prototype system shows promise for improvements to the key wireless power transmission metric, specific power density, by at least an order of magnitude to ~0.1 W/g.If successful, the outcomes of this AIR project would revolutionalize power delivery to portable sensors and equipment and transform the design space for implanted biosensors that measure and control biological functions in vivo.
