项目摘要

The broader impact/commercial potential of this I-Corps project is the development of a new class of smart fire protection blankets (SFPB) to protect citizens and firefighters from wildfires and/or sustaining dangerous exposures to excessive heat. Wildfires, now more common, can cause death from entrapment, burns, or asphyxiation; these mortalities have increased continuously since 2011. With the proposed technology, once the firefighter or first responder is exposed to moderate temperatures, the blanket undergoes a phase transformation and begins expanding, generating an air pocket. This reduces the heat flow from the fire to the firefighter’s skin, reducing burn injuries.This I-Corps project is based on the development of a new class of smart fire protection blankets utilizing shape memory elements. Layers of aluminum foil, fiberglass, Kevlar, fire-retardant sheets and a backing of silica weave will be interwoven with the shape memory elements. The fast actuation phase transformation characteristics are activated when excessive thermal exposures are detected. Once activated, the shape memory elements will expand and introduce air pockets inside the blanket that will reduce their thermal conductivity and also lower the risk of burns. The proposed smart garment will have self-tuning characteristics to adjust the thickness of the air pockets according to the ambient temperature.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.

I-Corps项目的更广泛影响/商业潜力是开发一种新型智能防火毯（SFPB），以保护公民和消防员免受野火和/或持续暴露在过热的危险中。野火，现在更常见，可导致死亡的陷阱，烧伤，或窒息；自2011年以来，这些死亡率持续上升。使用该技术，一旦消防员或第一响应者暴露在中等温度下，毯子就会发生相变并开始膨胀，产生一个气囊。这减少了从火到消防员皮肤的热流，减少了烧伤。这个I-Corps项目的基础是开发一种新型的智能防火毯，利用形状记忆元素。层叠的铝箔、玻璃纤维、凯夫拉纤维、阻燃片材和二氧化硅编织衬底将与形状记忆元素交织在一起。当检测到过度的热暴露时，快速驱动相变特性被激活。一旦被激活，形状记忆元件就会膨胀，并在毯子内部引入气穴，从而降低它们的导热性，降低烧伤的风险。提出的智能服装将具有自调谐特性，可以根据环境温度调整气囊的厚度。该奖项反映了美国国家科学基金会的法定使命，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。
