本项目支持德克萨斯A M大学电气和计算机工程系E Sanchez-Sinencio博士和埃及开罗大学Ahmed Nader Mohieldin博士之间的合作研究。 该研究将专注于电源管理电路的开发，该电路可以为电池更换或远程充电不切实际或根本不可行的系统或设备提供电源。 其中包括生物医学和工业无线传感器、家庭和楼宇自动化系统以及自动化仪表阅读。 智力优势。拟议的研究解决了需要演示，设计和测量，电源管理单元（PMU）具有低启动电压，从一个紧凑的电源，如热电发电机（TEG）。 这些发电机将周围环境能量转换为电能，但为了在变化的环境中有效，需要电源管理单元。 私家侦探？s将使用TEG和低成本互补金属氧化物半导体（CMOS）技术来开发PMU。 该方法将减小所需的TEG输出电压，并因此减小其面积;并且它将扩展给定尺寸的TEG的操作温度范围。更广泛的影响。整个能量收集解决方案的尺寸减小和工作温度范围宽，对于尺寸敏感的应用非常有吸引力。这两个PI将使用最先进的CMOS技术，在个人和团队研究项目中培训三名研究生（包括国内和代表性不足的群体）。项目结果将通过IEEE期刊和会议，研讨会和研讨会向所有研究生开放。研究结果将纳入本科和研究生课程的教学大纲。该项目由美国-埃及联合基金计划资助，该计划为两国的科学家和工程师提供赠款，以进行合作研究。

AbstractThis project supports collaborative research between Dr. E Sanchez-Sinencio, Department of Electrical and Computer Engineering, Texas Engineering Experiment Station, Texas A&M University and Dr. Ahmed Nader Mohieldin, Cairo University in Egypt. The research will focus on the development of a power management circuit that can provide power to systems or devices where battery replacement or remote charging is unpractical or simply not feasible. These include biomedical and industrial wireless sensors, home and building automation systems, and automated meter reading. Intellectual Merit. The proposed research addresses the need to demonstrate, design and measure, a power management unit (PMU) with a low startup voltage that operates from a compact power supply such as thermoelectric generators (TEG). These generators convert ambient environmental energy into electrical energy but to be effective in changing environments, a power management unit is needed. The PI?s will use TEGs and low cost complementary metal-oxide-semiconductor (CMOS) technology to develop the PMU. The approach will reduce the required TEG output voltage, and therefore its area; and it will extend the operating temperature range of a given size of the TEG. Broader Impact. The reduced size and wide operating temperature range of the overall energy harvesting solution will be very attractive to size-sensitive applications. The two PIs will train three graduate students (including domestic and under-represented groups) in individual and team research projects using state-of-the-art CMOS technologies. Project results will be disseminated through IEEE journals and conferences, workshops, and seminars open to all graduate students. The results will be incorporated into the syllabi of both undergraduate and graduate courses. The project is funded under the US-Egypt Joint Fund Program, which provides grants to scientists and engineers in both countries to undertake cooperative research.
