SBIR Phase I: Functionally Integrated Self Powering Flexible and Conformal Sensor System Components

NSF SBIR第一阶段提案1013698提案标题：功能集成自供电灵活和共形传感器系统组件摘要：这个小型企业创新研究(SBIR)第一阶段项目专注于开发一种灵活、坚固、保形、自供电的系统，具有集成的生成、收获、存储、传感和通信能力。灵活的外形规格适合和设计为具有常规和自主部署能力的小范围和大区域的广泛应用。到目前为止，大多数能量采集和自主传感器系统仅限于单个可清理的源，具有定制的大尺寸(约10-100 cm3)，导致昂贵的实施、有限的应用和商业部署。因此，这项建议侧重于将微功率采集、高效能源管理电路和系统以及已展示的一系列薄膜多功能材料整合在一起，例如柔性互补金属氧化物半导体(CMOS)电路、太阳能电池和有机发光二极管(OLED)以及高效压电材料。这项提议的目标将解决在紧凑灵活的外形中整合能源产生、采集、存储、传感、监测和通信电路功能的关键任务，这被设想为创建独立共形系统的首次尝试。经过单独验证的薄膜工艺正在设计为集成在线性、可制造、低成本和大容量兼容工艺中。该项目更广泛的影响/商业潜力涉及广泛的国防、工业和消费应用，这些应用需要自供电和长寿命自主电子系统，这些系统将成为未来十年的关键应用领域之一。这些设备包括无线传感器网络、远程结构健康监测、无法访问的温度和湿度传感、射频识别(RFID)标签和植入式生物传感器。此外，传感器和cmos电路尺寸和功耗的减少增加了遥感的普及，特别是在危险和难以接近的环境中。除了基本的外形因素和有效寿命限制外，电池的充电和更换可能既繁琐又昂贵。在当前和随后的赠款阶段，建议开发多功能薄膜材料并将其整合到通用和特定应用解决方案中，并将其商业化。可以预见，这些系统将以灵活、保形的形式实施，适用于更广泛的应用，如智能织物、体育、医疗保健、供应链管理、标签、信用卡、生物传感贴片和大面积现场部署，即使在传统纽扣电池不实用的环境中也是如此，使这些解决方案能够实现未来十年十大重要新兴技术中的至少三项。

NSF SBIR Phase I Proposal 1013698Proposal Title:Functionally Integrated Self-powered Flexible and Conformal Sensor System ComponentsAbstract:This Small Business Innovation Research (SBIR) Phase I project focuses on developing a flexible, rugged, conformal form factor, self-powered system with integrated generation, harvesting, storage, sensing, and communication capability. The flexible form factor is suitable and designed for broad ranges of applications in small and large areas with conventional and autonomous deployment capability. To date most energy harvesting and autonomous sensor systems are limited to a single scavengable source with custom fabricated large form factors (~10-100 cm3) resulting in costly implementations, limited applications and commercial deployment. Consequently, this proposal focuses on integration of micropower harvesting, efficient energy management circuits and systems along with demonstrated range of thin-film multifunction materials such as flexible complementary metal-oxide-semiconductor (CMOS) circuits, solar cells and organic light emitting diodes (OLEDs), and high efficiency piezoelectric materials. The goal of this proposal will address the critical tasks of integration of energy generation, harvesting, storage, sensing, monitoring and communication circuit functions in a compact flexible form factor, envisioned to be the first such attempt to create a standalone conformal system. The thin-film processes proven individually are being designed to be integrated in linear, manufacturable, low cost and high volume compatible processes.The broader impact/commercial potential of this project involves broad range of defense, industrial, and consumer applications that require self-powered and long life autonomous electronic systems that are emerging as one of the critical application segments in the coming decade. These span wireless sensor networks, remote structural health monitoring, inaccessible temperature and humidity sensing, radio-frequency identification (RFID) tags, and implantable biosensors. In addition, reduction in the size and power consumption of sensors and CMOS circuitry has increased proliferation of remote sensing especially in hazardous and inaccessible environments. Along with the fundamental form factor and active life limitation concern with batteries is their charging and replacement can be tedious and expensive. Development of multifunctional thin-film materials and their integration in generic and specific application solutions is proposed during the current and subsequent grant phases, and their commercialization. These systems can be envisioned to be implemented in flexible, conformal form factors suitable for broader applications such as smart fabrics, sports, health care, supply chain management, labels, credit cards, bio sensing patches and large area field deployment even in environments where conventional button cells are not practical making the solutions enabling at least three of the ten significant emerging technologies of the coming decade.
