SBIR Phase II: Self-Powering Textiles for Electronic Wearables

这个小型企业创新研究（SBIR）项目的更广泛的影响/商业潜力是实现无线物联网（IoT），可穿戴传感器和可穿戴产品的创新。便携式电能是许多技术设备中的关键部件。该项目推进了一项变革性技术，将能量捕获、存储和输送集成到单个设备中，以提高小型电子设备的便携性和实用性。SBIR第二阶段项目旨在克服无线物联网、可穿戴设备和电子产品面临的两个关键挑战：电池寿命和频繁更换电池带来的昂贵不便。该项目将先进的太阳能电池、超级电容器和电力电子技术集成到一个单元（超级电池）中，可以轻松连接到电子负载。设计重点包括物理灵活性、宽工作温度范围、热管理、超低等效串联电阻和泄漏、高储能容量和良好的工作效率。该方法将太阳能电池和超级电容器技术配对，相互补充。与一次性电池或分立太阳能电池相比，其优点包括尺寸、重量和安装寿命成本。该奖项旨在通过提供比现场可更换电池或分立式太阳能电池更好的能源来加速物联网、可穿戴设备和电子技术的采用。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

The broader impact/commercial potential of this Small Business Innovation Research (SBIR) project is to enable innovations in wireless Internet-of-Things (IoT), wearable sensors, and wearable products. Portable electric energy is a key component in many technological devices. This project advances a transformative technology that integrates energy capture, storage, and delivery into a single device to advance the portability and utility of small electronic devices. This SBIR Phase II project proposes to overcome two key challenges faced in wireless IoT, wearable, and electronic products: battery life, and the costly inconvenience of frequently replacing batteries. The project integrates advanced solar cell, supercapacitor, and power electronic technologies into a single unit (Supercell) easily connected to electronic loads. Design priorities include physical flexibility, wide operating temperature range, heat management, ultra-low Equivalent Series Resistance and leakage, high energy storage capacity, and good operating efficiency. The approach pairs solar cell and supercapacitor technologies to work together, each complementing the other. Advantages include size, weight, and installed lifetime cost, when compared with single-use batteries, or with discrete solar cells. The proposed work will accelerate adoption of IoT, wearable, and electronic technologies by offering a better source of energy than field-replaceable batteries or discrete solar cells.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.
