The broader impact/commercial potential of this I-Corps project is the development of focused ultrasound technology. This technology could eliminate traditional surgeries and invasive therapy complications. This technology can also be made at a competitive price point allowing it to be more accessible, especially to clinics in low-income communities. This technology also removes some of the major performance barriers in the market. A proposed miniaturized ultrasound solution can be deployed in numerous portable applications, such as ultrasonic deep brain stimulator, which eliminates complications and cost of current treatments, and can be used in other emerging applications such as mental health treatments, without opening the skull and implanting electrodes into a patient's brain.This I-Corps project is based on the development of an ultrasound transducer drive system. Multichannel phased arrays and single channel power modules are ultrasound transducer drivers, which are used in a wide range of medical and non-medical applications. These drivers are very high in price, and they have performance variances. This innovation reduces the cost of these drivers with some performance breakthroughs, such as generation of sine or harmonic-free outputs beneficial for both medical and nonmedical applications, as well as the removal of the matching networks per transducer and providing an increase in the power limitations of each channel. This technology can be deployed in focused ultrasound medical applications to cure a wide range of conditions non-invasively, with these harmless soundwaves. The technology can also be deployed in other non-medical applications, where economical and high-performance drivers are necessary. The technology is supposed to be miniaturized to replace current severely invasive deep brain stimulation with non-invasive ultrasound version used for different neurologic conditions, such as Epilepsy and Parkinson.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该I-Corps项目的更广泛的影响/商业潜力是开发集中的超声技术。这项技术可以消除传统的手术和侵入性疗法并发症。这项技术也可以以具有竞争力的价格来制定，使其更容易获得，尤其是对于低收入社区的诊所。该技术还消除了市场上一些主要的性能障碍。提出的微型超声解决方案可以部署在许多便携式应用中，例如超声波深脑刺激剂，从而消除了当前处理的并发症和成本，并且可以在其他新兴应用中使用，例如心理健康处理，例如，无需打开颅骨和将电极植入患者的大脑中的电极。多通道分阶段阵列和单通道功率模块是超声传感器驱动程序，用于广泛的医疗和非医疗应用。这些驱动程序的价格很高，并且具有性能差异。这项创新通过一些性能突破降低了这些驱动因素的成本，例如有益于医疗和非医学应用程序，以及消除每个传感器的匹配网络并提供每个通道功率限制的增加。这些技术可以通过这些无害的声波来部署在集中的超声医疗应用中，以无创地治疗多种疾病。该技术也可以部署在其他非医疗应用中，在这些应用程序中，需要经济和高性能驱动因素。该技术被认为是小型化的，以替代当前的严重侵入性深层大脑刺激，用于用于不同神经系统条件的非侵入性超声版本，例如癫痫和帕金森氏症。该奖项反映了NSF的法定任务，并被认为是通过基金会的知识分子和更广泛影响的评估来评估CRITERIA的评估。
