Towards clothing-like neural sensing and stimulation: thin, but robust, wearable electronics

基于柔性电子技术的可穿戴生物传感器的新兴技术正在对患者的康复产生重大影响。感官电子产品从刚性到柔性的转变给患者带来了前所未有的舒适感，特别是当佩戴在身体的活动部位时。生物传感器的第一步是要达到舒适程度，就像在身体的活动部位穿衣服一样。然而，由于导电/计算组件与基板/封装剂之间的模量不匹配以及由于缺乏粘附性而导致组件之间的分层，柔性电子元件的构成组件容易失效。在这里，我们将(i)对机械失效模型进行基础研究，（ii）基于先前发布的方法提出替代材料/设备设计（即，与NSERC Engage项目规则无关的知识产权问题），以及（iii）测试与可穿戴性和寿命相关的设备的机械性能。

The emerging technology of wearable biosensors based on flexible electronics technology is making a greatimpact on the rehabilitation of patients. The transition of form factor of sensory electronics from rigid toflexible allowed unprecedented comfort to the patients, especially when worn on the moving parts of body. Thefirst step for the biosensors is to achieve the comfort level that is comparable to wearing clothing on themoving parts of body. The constituting components for flexible electronics are, however, prone to fail due tomodulus mismatch between conducting/computing components and the substrate/encapsulants anddelamination between the components due to the lack of adhesion. Here, we will (i) perform fundamentalresearches on mechanical failure models, (ii) suggest alternative material/device designs based on previouslypublished methods (i.e., no intellectual property issues related to the rules of NSERC Engage project), and (iii)test the mechanical properties of devices that are pertinent to wearability and longevity.
