Multiple sensing functional devices enable to collect a variety of information for the next class of Internet of Things (IoT) concept such as medical/healthcare, robotics, environment, and infrastructures. In addition to the functionalities, mechanical flexibility allows to attach the devices over non-planar surfaces conformally, resulting in that more information can be monitored precisely. In particular, multi-functional electronic skin (e-skin) can contribute to the applications of healthcare, robotic skin, and infrastructure due to low-cost, macro-scale devices that can cover a variety of objects including human bodies.
This talk will introduce the flexible circuits and sensors from the fundamental mechanism and characteristics to the flexible sensor applications. Especially, using the unique properties of flexible and thin film sensor sheets, a variety of applications are described such as healthcare monitoring, wind flow mapping, plant dehydration, and soft robotics, which cannot be realized easily by using conventional inflexible chip-based sensors. Furthermore, the challenges to measure the information from the targeted object without affecting environmental conditions and some others will also be discussed to move forward to building the platform for the practical flexible sensor sheet systems.
多传感功能器件可以为新一代物联网技术收集各种信息，在医疗健康、机器人、环境、基础设施等领域具有广泛应用。此外，柔性传感器的机械灵活性有利于实现设备与非平面物体表面共形接触，从而可以精确监测更多有价值的信息。多功能电子皮肤 (E-skin) 由于其低成本、大尺寸、可覆盖包括人体表皮在内的多种物体表面而受到广泛关注。
本报告将介绍柔性电路和传感器的基本原理、特点及其应用。特别地，利用柔性和薄膜型传感器的独特性能，本报告将介绍柔性传感器在医疗健康监测、大范围流体监测、植物脱水以及软体机器人等方面的应用。这些应用无法基于传统刚性芯片传感器轻易实现。另外，本报告还将讨论在不影响环境原始属性的情况下从目标对象测量获取信息存在的挑战，以及其它一些挑战。这些问题的解决将进一步推进柔性传感器系统平台的实际应用。
