Imagine a headband that can provide real-time physiological health status from sweat. Continue to imagine having an ability to check regularly the tap water quality. Both can be provided by robust integrated sensing platforms, which are important in developed countries (such as Canada) and critical in the Developing World. Creating such systems requires the integration of flexible, soft and hard materials and components into a single packaged system. This is an extremely challenging task because of their surface and bulk properties' incompatibilities. This precludes excessive heat or pressure, or glue during integration. We propose to develop Surface Activated nanoBonding (SAB) methodologies for heterogeneous materials integration to create the technology platforms, with a focus on applications for monitoring physiological health and water quality parameters. Surface activation refers to the cleaning of native oxides and carbon contaminants from the surface. We will focus on the SAB-based bonding and integration technologies to overcome the attaching difficulties in the current bonding and packaging technologies. Therefore, it is an enabling factor to develop a research program with a strategic and unique manner to create health and water diagnostic systems.We will focus on the following. Exploring fundamental science and innovative technologies of SAB for integration of flexible, soft, and hard materials without external pressure, adhesive, heat, or chemicals. Application of SAB-based bonding and integration technologies in design, fabrication, and characterization of sensing electrodes, micro-heater element, and microfluidic component to create sustainable integrated water-quality monitoring in pipeline. Application of SAB-based bonding and integration technologies in design, fabrication, and characterization of sensing electrodes, sweat extraction electrode, and microfluidic component to create wearable sweat monitoring system. The novelty of the proposed research is the result of SAB-based science and technology of materials, components, and devices integration to create fully integrated, robust, and sustainable monitoring systems. The research is also highly significant as it focuses on novel, emerging applications with a high interest and need in the health and environmental sciences, along with mining and industrial monitoring. In health monitoring, the proposed research is particularly attractive for detecting early symptoms of diseases like cancer. According to Reuters Health on 21 April 2017 “A next step in wearable health sensors might be a device that causes a patch of skin to sweat, then analyzes the perspiration to monitor or even diagnose disease”. This research program will provide Canada with the knowledge and HQP necessary to lead the commercialization of these next-generation systems' integration technologies.

想象一下，一个头带可以从汗液中提供实时的生理健康状况。继续想象有能力定期检查自来水的质量。这两者都可以通过强大的综合传感平台来提供，这在发达国家（如加拿大）很重要，在发展中国家也很关键。创建这样的系统需要将柔性、软质和硬质材料和组件集成到单个封装系统中。这是一项极具挑战性的任务，因为它们的表面和本体性质的不相容性。这就排除了在集成过程中的过热或过压或胶合。我们建议开发用于异质材料集成的表面活化纳米键合（SAB）方法，以创建技术平台，重点关注用于监测生理健康和水质参数的应用。表面活化是指从表面清除天然氧化物和碳污染物。我们将专注于基于SAB的键合和集成技术，以克服当前键合和封装技术中的附着困难。因此，以战略性和独特的方式开发研究计划以创建健康和水诊断系统是一个有利因素。我们将重点关注以下内容。 探索SAB的基础科学和创新技术，在没有外部压力、粘合剂、热量或化学品的情况下集成柔性、软质和硬质材料。基于SAB的键合和集成技术在传感电极、微加热器元件和微流体组件的设计、制造和表征中的应用，以创建可持续的集成管道水质监测。 基于SAB的键合和集成技术在传感电极、汗液提取电极和微流体组件的设计、制造和表征中的应用，以创建可穿戴汗液监测系统。拟议研究的新奇是基于SAB的材料，组件和设备集成科学和技术的结果，以创建完全集成，强大和可持续的监测系统。这项研究也是非常重要的，因为它侧重于新的，新兴的应用与高度的兴趣和需要在健康和环境科学，随着沿着采矿和工业监测。在健康监测方面，拟议的研究对于检测癌症等疾病的早期症状特别有吸引力。据路透社健康2017年4月21日报道，“可穿戴健康传感器的下一步可能是一种设备，它可以使一片皮肤出汗，然后分析汗液以监测甚至诊断疾病”。该研究计划将为加拿大提供必要的知识和HQP，以领导这些下一代系统集成技术的商业化。
