The rapidly declining power usage of modern sensors, actuators, wearable electronics, communications and biomedical devices is opening new possibilities for portable autonomous systems that are powered by available ambient energy, such as the motion or heat from a person, motion of air or water, or sound and vibrations. The need for inexpensive, reliable systems that can convert available ambient energy into useful forms for these technologies is one of the biggest limitations in their development. This research program seeks to help fill this need by furthering the development of two novel branches of direct energy conversion (DEC) systems. The focus will be placed on developing, characterizing, and further advancing novel thermoelectric (TE) and thermoacoustic (TAC) DEC systems incorporating nano-particle enhanced transport media (NTM) (e.g., nano-composites, nanofluids). The proposed research will look specifically at DEC from ambient energy sources (also known as low potential sources or LPSs). However, LPSs are usually intermittent in nature. Therefore, practical DEC systems require integrated energy storage systems to ensure continuously delivering power. Latent heat thermal energy storage (LHTS) can be integrated into DEC systems to provide continuous energy supply and is also included in this research program. Currently, energy conversion and storage efficiencies of conventional TE, TAC, and LHTS systems are low. However, recent advancements in nanotechnology open the possibility of improving these systems' efficiencies by incorporating NTM. The proposed research program includes developing mathematical models that describe mass, momentum, energy, and electrical charge transfer processes in DEC and LHTS systems incorporating emerging NTM. These models will be applied to characterize and optimize new DEC systems that integrate NTM and LHTS. Model development will require new analytical and numerical solution techniques. Model predictions will be validated by prototyping DEC systems and experimentally characterizing performance. This research program will significantly improve our understanding of the complex transport processes inside DEC and LHTS systems incorporating NTM. This understanding will lead to more practical and efficient TE and TAC systems integrating LHTS. These novel systems will be commercializable in a range of applications including cooling (e.g., electronics cooling, remote air-conditioning, battery thermal management in electric/hybrid vehicles), as components of green buildings (e.g., thermally active walls), medical imaging, and power generation for wearable/mobile electronics. This research program will also train HQP who will become engineers/researchers with deep knowledge of DEC, LHTS, and NTM, expertise which will be essential to the commercialization and further development of new DEC systems incorporating NTM.

现代传感器，执行器，可穿戴电子，通信和生物医学设备的功率使用迅速下降正在为可随机的自主系统开辟了新的可能性，这些系统由可用的环境能量提供动力，例如人的运动或热量，空气或水的运动，或声音和振动。需要将可用的环境能源转换为这些技术的有用形式的廉价，可靠的系统的需求是其开发中最大的局限性之一。 该研究计划旨在通过促进两个直接能量转换（DEC）系统的两个新分支来帮助满足这一需求。将重点放在开发，表征和进一步推进新型热电（TE）和热声（TAC）DEC系统中，这些系统结合了纳米颗粒增强的传输介质（NTM）（例如纳米 - 复合材料，纳米流体）。拟议的研究将特别考虑来自环境能源（也称为低潜在来源或LPS）的DEC。但是，LPS通常是间歇性的。因此，实用的DEC系统需要集成的储能系统，以确保不断传递功率。潜热热能存储（LHT）可以集成到DEC系统中以提供连续的能源供应，并且还包括在该研究计划中。当前，常规TE，TAC和LHTS系统的能源转换和存储效率较低。但是，纳米技术的最新进展为通过合并NTM提高了这些系统的效率开辟了可能性。 拟议的研究计划包括开发数学模型，描述DEC和LHTS系统中纳入新兴NTM的质量，动量，能量和电荷转移过程。这些模型将用于表征和优化整合NTM和LHT的新DEC系统。模型开发将需要新的分析和数值解决方案技术。模型预测将通过原型DEC系统和实验表征性能来验证。 该研究计划将大大提高我们对DEC内部和LHTS系统内的复杂运输过程的理解。这种理解将导致更实用，高效的TE和TAC系统整合LHT。这些新型系统将在一系列应用中进行商业化，包括冷却（例如，电子冷却，远程空调，电/混合动力汽车中的电池热管理），作为绿色建筑物（例如，热活动墙壁）的组件，医疗成像和可耐磨性/移动电子产品的发电。 该研究计划还将培训HQP，HQP将成为对DEC，LHTS和NTM深入了解的工程师/研究人员，这对于将NTM的新DEC系统的商业化和进一步开发至关重要。
