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.

该NSF加速创新研究（AIR）项目将构成一项实质性的全国努力，以将纳米型和纳米质研究发现转化为生物传感应用中的创新产品。 实施这些生物传感器的挑战涉及传递能力以推动目标生物反馈的传感器的方法。 该空气项目建议使用纳米质的超材料方法来建模并展示一个紧凑的定向功率收集系统，该系统依赖于亚波尺度阵列阵列结构，以产生整流的天线或直肠。 一个原型系统显示出对关键无线功率传输指标（特定功率密度）的改进的希望，至少达到〜0.1 W/g。
