The objective of this Small Sensor Team (SST)/Collaborative Research project is to significantly improve the observability in polymer processing operations by providing feedback of pressure, temperature, flow rate, and other process states at multiple locations within the mold cavity, for real-time process and quality control. This objective will be achieved through simultaneous in-mold pressure-temperature sensing, multi-domain signal processing, and injection molding process analysis.The benefit of this research is that it will introduce a new generation of miniaturized sensors that can be placed at practically anywhere within the mold cavity that are previously not possible, and in much less time than previously required to modify a mold for placing a conventional sensor. The broader impact of this research is three-fold: 1) it represents a radical step forward from the current wired sensors that have been used for decades, and has the potential to significantly improve molding productivity wherein each percentage point improvement corresponds to cost savings over $40 million per year, 2) the new sensing technique will not only be applicable to injection molding, but also to other high-energy manufacturing processes, and 3) the research will contribute substantially to multidisciplinary education and training of graduate and undergraduate students and enhance manufacturing curriculum development at the PIs' institutions.

这个小型传感器团队（SST）/合作研究项目的目标是通过在模腔内多个位置提供压力、温度、流速和其他工艺状态的反馈，显着提高聚合物加工操作的可观察性，以实现实时工艺和质量控制。这一目标将通过同时进行模内压力-温度传感、多域信号处理和注塑工艺分析来实现。这项研究的好处是，它将引入新一代的小型化传感器，这些传感器可以放置在模腔内的几乎任何地方，这在以前是不可能的，而且比以前修改模具以放置传统传感器所需的时间要少得多。这项研究的广泛影响有三个方面：1）它代表了从已经使用了几十年的当前有线传感器向前迈出的根本性一步，并且具有显著提高模制生产率的潜力，其中每一个百分点的提高对应于每年超过4000万美元的成本节约，2）新的感测技术将不仅适用于注塑，而且也适用于其他高能制造过程; 3）该研究将大大有助于研究生和本科生的多学科教育和培训，并加强PI机构的制造课程开发。
