Abstract
Self-powered wearable sensor systems can not only increase adoption and compliance but also enable long-term and continuous monitoring of key health and environmental parameters. To achieve this, wearable devices must integrate a multimodal array of sensors that enable non-invasive, continuous, real-time monitoring, have a long operational lifetime to gather meaningful long-term data, and remain comfortable and flexible to ensure user adoption. The National Science Foundation-funded Center for Advanced Self-Powered Systems of Integrated Sensors and Technologies (ASSIST) is developing precisely such devices, capable of continuous monitoring of personal environments and health. These capabilities are made possible by breakthroughs in power management, low-power electronics, and innovative health and environmental sensors, all seamlessly integrated into wearable, comfortable form factors. In this talk, I will specifically focus on how advances in energy harvesting and sensor systems are making continuous monitoring a reality. Innovations in thermoelectric and piezoelectric harvesters, catalyzed by optimized system design and flexible materials, have enabled long-term operation of sensors for vigilant monitoring. Sensor advances in electronic-nose, optical imaging and human health are providing a complete multi-modal picture into human health and its relationship environment. I will also present the applications that these sensor systems are enabling such as long-term sensing and effective management of chronic conditions, sensing of personal exposure to air pollutants and toxins and longitudinal studies that provide new insight into correlation of various health and environmental parameters. I will also provide examples of translation of sensor systems and innovative education of the engineering pipeline enabled by the ecosystem associated with an NSF engineering research center.
