操作可注射的细胞级光电组件的无线控制和功率收集系统在神经调节技术（如光遗传学）中提供了重要的经证实的能力。在这里，我们报告了一种射频（RF）控制/收获设备，与以前报道的技术相比，该设备提供了显著减小的尺寸，减轻的重量和提高的效率。该平台与双结、多结、高效太阳能电池的结合使用，可以将发射的RF功率降低百倍，从而大大增强无线覆盖范围。对小鼠社会群体的光遗传学研究证明了这些系统的实用性，并表明它们在神经科学中广泛使用的潜力。
Wireless control and power harvesting systems that operate injectable, cellular-scale optoelectronic components provide important demonstrated capabilities in neuromodulatory techniques such as optogenetics. Here we report a radio frequency (RF) control/harvesting device that offers dramatically reduced size, decreased weight and improved efficiency compared to previously reported technologies. Combined use of this platform with ultrathin, multijunction, high efficiency solar cells allows for hundred-fold reduction of transmitted RF power, which greatly enhances the wireless coverage. Optogenetics studies with social groups of mice demonstrate the utility of these systems, and suggest their potential for widespread use in neuroscience.
