The broader impact/commercial potential of this I-Corps project lies in the broad field of electrically-safe, cold plasma technology. The specific application are quite broad in scope. One potential commercial application area involves sterilization of medical instruments, food, and pharmaceutical products. The system developed here is electrically safe for personnel and sensitive equipment used in manufacturing environments. Another potential application involves utilization of the cold plasma technology for medical treatment subject to strict electromagnetic interference requirements of other medical equipment in same surgical procedure. This project will explore the commercial potential of the core technology and will inform further technical developments and possible commercialization paths.This I-Corps project further develops a novel cold plasma technology, namely DC voltage driven cold plasma technology. Recent work has demonstrated that cold plasmas can be generated in self-oscillatory regime, when sequence of streamer-type breakdowns in gas flow is driven by purely DC high voltage. This approach differs from the traditional AC and pulsed-DC, where breakdown repetition rate is governed by the frequency of discharge driving voltage. The repetition frequency of the breakdowns in this innovative approach can be controlled by the geometry of discharge electrodes and surroundings. DC voltage driven cold plasma technology has tremendous fundamental advantages over the traditional AC and pulsed-DC systems including very effective mitigation of unwanted breakdowns and corona, elimination of electromagnetic interference, significant improvement of breakdown and electric shock safety, and overall simplicity of the system and enables multiple commercial applications.

这个I-Corps项目更广泛的影响/商业潜力在于广泛的电气安全，冷等离子体技术领域。具体应用范围相当广泛。 一个潜在的商业应用领域涉及医疗器械、食品和药品的灭菌。 这里开发的系统对于制造环境中使用的人员和敏感设备是电气安全的。另一个潜在的应用涉及利用冷等离子体技术进行医疗，在同一外科手术中，其他医疗设备的电磁干扰要求严格。该项目将探索核心技术的商业潜力，并将为进一步的技术发展和可能的商业化路径提供信息。该I-Corps项目进一步开发了一种新的冷等离子体技术，即直流电压驱动冷等离子体技术。最近的工作表明，冷等离子体可以产生自振荡制度时，在气流中的流光型击穿序列是由纯直流高压驱动。这种方法不同于传统的AC和脉冲DC，其中击穿重复率由放电驱动电压的频率决定。在这种创新方法中，击穿的重复频率可以通过放电电极的几何形状和环境来控制。直流电压驱动的冷等离子体技术与传统的交流和脉冲直流系统相比具有巨大的基本优势，包括非常有效地减轻不必要的击穿和电晕，消除电磁干扰，显著改善击穿和电击安全性，以及系统的整体简单性，并实现多种商业应用。
