The broader impact/commercial potential of this Small Business Innovation Research (SBIR) Phase I project is to develop a soft, durable, and completely flexible pressure mapping surface with application in long-term care bedding for the prevention of pressure sores and ulcers. The project will advance a process to transform current foam materials and compliant components into high-accuracy deformation sensors. Treating pressure sores costs nearly $10 B in the US, and thousands of related lawsuits are filed every year. For patients, pressure sores can add up to an additional $40 k in hospital bills. This project will develop a medical sensing technology by combining the properties of sensing composite foam with efficient algorithms for electrical capacitive tomography (ECT). This system will lead to applications such as prosthetics monitoring comfort levels, diabetic insoles/midsoles monitor pressure hotspots, industrial gaskets and seals that self-monitor, wheelchair pads that can monitor pressure, and automotive/airplane seats that automatically adjust to maximize comfort. This Small Business Innovation Research (SBIR) Phase I Project will develop a system to prevent pressure ulcers associated with long-term care, the treatment of which results in a cost of $10 B annually with several objectives: 1) Develop a shape-reconstruction algorithm based on electrical capacitive tomography (ECT). 2) Develop and prototype a composite foam surface providing a similar feel to currently used materials but generating an appropriate change in capacitance when compressed. 3) Adapt the composite foam technology to lower-density foams typically found in bedding products. 4) Construct a full-scale prototype to test the ability to accurately measure pressure across the entire surface, optimize sensing resolution, and investigate attachment methods for the ECT electrodes. 5) Conduct a large-scale manufacturability review for scalability of the product in both materials manufacturing and electrical assembly.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.

该小型企业创新研究（SBIR）第一阶段项目的更广泛影响/商业潜力是开发一种柔软、耐用和完全灵活的压力映射表面，用于长期护理床上用品，以预防压疮和溃疡。该项目将推进一个过程，将当前的泡沫材料和顺应性组件转化为高精度变形传感器。在美国，治疗压疮的费用接近10 B美元，每年都会提起数千起相关诉讼。对于病人来说，压疮可以增加高达4万美元的额外医院账单。该项目将通过将传感复合泡沫的特性与电容层析成像（ECT）的有效算法相结合来开发医疗传感技术。该系统将导致应用，如假肢监测舒适度，糖尿病鞋垫/中底监测压力热点，工业垫圈和密封件，自我监测，轮椅垫，可以监测压力，汽车/飞机座椅，自动调整，以最大限度地提高舒适度。这个小型企业创新研究（SBIR）第一阶段项目将开发一个系统，以防止与长期护理相关的压疮，其治疗每年的成本为10 B美元，有几个目标：1）开发一种基于电容层析成像（ECT）的形状重建算法。2)开发并制作复合泡沫表面的原型，该表面提供与当前使用的材料相似的感觉，但在压缩时会产生适当的电容变化。 3)将复合泡沫技术应用于床上用品中常见的低密度泡沫。4)构建一个全尺寸原型，以测试准确测量整个表面压力的能力，优化传感分辨率，并研究ECT电极的连接方法。5)对产品在材料制造和电气组装方面的可扩展性进行大规模的可制造性审查。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。
