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、耐用且完全灵活的压力测绘表面，应用于长期护理床上用品，以预防压疮和溃疡。该项目将推进将现有泡沫材料和柔性组件转变为高精度变形传感器的工艺。在美国，治疗压疮的费用接近 10 美元，每年都会提起数千起相关诉讼。对于患者来说，压疮可能会额外增加 4 万美元的住院费用。该项目将通过将传感复合泡沫的特性与电容断层扫描（ECT）的高效算法相结合来开发医疗传感技术。该系统将带来诸如监测舒适度的假肢、监测压力热点的糖尿病鞋垫/中底、自我监测的工业垫圈和密封件、可以监测压力的轮椅垫以及自动调节以最大限度地提高舒适度的汽车/飞机座椅等应用。这个小型企业创新研究 (SBIR) 第一阶段项目将开发一个系统来预防与长期护理相关的压疮，其治疗每年的成本为 10 B 美元，其目标如下：1) 开发基于电容断层扫描 (ECT) 的形状重建算法。 2) 开发复合泡沫表面并制作原型，提供与当前使用的材料类似的感觉，但在压缩时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) 构建全尺寸原型来测试精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) 对材料制造和电气装配中产品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智力优点和更广泛的影响审查标准进行评估，被认为值得支持。
