Intellectual MeritElectronics provide powerful capabilities when interfaced with the body. Their miniaturization over the past few decades has paved way for tiny devices capable of biological sensing or stimulation, and hold promise for restoring physiological functions in patients. Although electronics can be made extremely small, existing methods for powering them involve large batteries or energy harvesting modules. The size of these powering components severely constrains the integration of electronics in living systems. The research in this proposal aims to overcome these challenges and enable arrays of optoelectronic probes small enough to be directly injected into the body. Routes to miniaturization are provided by the midfield wireless powering approaches recently established in the PI's lab. These approaches allow the transfer of power to nearly any location in the body at performance levels far exceeding requirements for both complex electronics and physiological stimulation. The research combines a fundamental understanding of power transfer physics with advances in low-power integrated circuits to demonstrate tiny yet fully operational sensors, electrodes, light sources, RF transceivers, and other classes of injectable electronics. Such capabilities represent a considerable advance in applying physics, wireless technology, and integrated circuits towards addressing challenges in biology and medicines.Broader ImpactsThe proposed research enables the integration of electronics into the body through tiny devices, providing previously unavailable diagnostic and therapeutic options such as minimally invasive surgery and continuous monitoring. These capabilities will accelerate scientific discovery and improve overall healthcare cost. To maximize research benefits, results will be synthesized in formats understandable to the general public, including clinicians, patients, and policy makers; and widely disseminated through online platforms. The popular appeal of robotic microsystems, will be leveraged to motivate and inspire high school students over the grant period to strengthen the STEM pipeline in the U.S. This is done through the internship of local K-12 teachers to multiply impact, mentoring of underrepresented students, and an annual summer workshop on robotics with biomedical applications for local high school students. The PI will also leverage her experience in mentoring female students at the high school level to encourage them to pursue higher degrees in engineering.

智能MeritElectronics在与身体连接时提供强大的功能。在过去的几十年里，它们的小型化为能够进行生物传感或刺激的微型设备铺平了道路，并有望恢复患者的生理功能。虽然电子产品可以做得非常小，但现有的供电方法涉及大型电池或能量收集模块。这些供电组件的尺寸严重限制了电子设备在生命系统中的集成。该提案中的研究旨在克服这些挑战，并使光电探针阵列足够小，可以直接注入体内。PI实验室最近建立的中场无线供电方法提供了小型化的途径。这些方法允许以远远超过复杂电子器件和生理刺激要求的性能水平将功率传输到身体中的几乎任何位置。该研究结合了对功率传输物理学的基本理解和低功耗集成电路的进步，展示了微小但完全可操作的传感器、电极、光源、RF收发器和其他类型的可注入电子器件。这些能力代表了在应用物理学、无线技术和集成电路应对生物学和医学挑战方面的一个相当大的进步。更广泛的影响拟议的研究能够通过微小的设备将电子设备集成到人体中，提供以前无法提供的诊断和治疗选择，如微创手术和连续监测。这些功能将加速科学发现并改善整体医疗成本。为了最大限度地提高研究效益，将以包括临床医生、患者和政策制定者在内的公众可以理解的格式综合研究结果，并通过在线平台广泛传播。机器人微系统的流行吸引力，将被用来激励和激励高中学生在赠款期间加强美国的STEM管道，这是通过当地K-12教师的实习来实现的，以增加影响，指导代表性不足的学生，以及为当地高中生举办的机器人生物医学应用年度夏季研讨会。PI还将利用她在高中阶段指导女学生的经验，鼓励她们攻读更高的工程学位。
