Transforming hard, rigid electronics into pliable devices that can conform to the contours of the human body will redefine the human-computer interaction, delivering electrical functions like biosensors, illumination, and energy storage to the human body. One approach to wearable electronics involves integrating electronic devices with soft, rubbery elastomers that can be laminated on the skin, intimately connecting devices with humans. Another approach integrates electronic devices with the textile fibers of clothing to make interacting with devices as simple as getting dressed. Both approaches face the challenge of mismatched mechanical properties of the electronic device materials, which are not intrinsically stretchable, and the soft rubber or textile substrates. Our research program aims to advance the field of soft, wearable electronics by developing new ways to integrate electronic materials and devices with elastomers and textiles. Our approach engineers the properties of the soft substrate to influence the mechanical and electrical response of electronic materials and devices deposited on the surface. This program will advance elastomer-based electronics by transforming the elastomeric substrate from a simple platform for stretchable devices into a multifunctional element that enhances the function of stretchable devices. Fusing a membrane of one elastomer onto the surface of a second combines the advantageous surface and bulk properties of the two elastomers; furthermore, the material that forms the interface between the two elastomers is a key synergistic element that will be exploited to favourably influence the function of stretchable materials and devices on the membrane surface. This program will also advance textile-based wearable devices by developing highly conductive and stretchable fabrics and fibers, using a low-cost, solution-based, scalable method that integrates high electrical conductivity while maintaining the soft, stretchable properties of the textile. The new stretchable and conductive textiles will be used to explore a wide range of innovative new devices, such as stretchable wiring integrated in clothing to connect devices, fiber-based strain sensors designed to detect body motion and measure vital signs like heartrate and respiration, and stretchable light-emitting fabrics and fibers, the ultimate integration of device functionality with clothing.

将坚硬，刚性的电子设备转换为可以符合人体轮廓的柔软设备，将重新定义人类计算机的相互作用，从而向人体传递诸如生物传感器，照明和能量存储之类的电函数。可穿戴电子产品的一种方法是将电子设备与柔软的橡胶弹性体集成在一起，可以在皮肤上层压，并将设备与人类紧密地连接。 另一种方法将电子设备与衣服的纺织纤维集成在一起，以使与穿着一样简单的设备进行交互。 两种方法都面临着不可本质上可拉伸的电子设备材料和软橡胶或纺织底物的机械性能的挑战。 我们的研究计划旨在通过开发将电子材料和设备与弹性体和纺织品集成的新方法来推动柔软，可穿戴电子产品的领域。 我们的方法工程师软底物的特性会影响沉积在表面上的电子材料和设备的机械和电响应。该程序将通过将弹性底物从简单的平台转换为可伸缩设备的简单平台转换为一个多功能元素，从而提高基于弹性的电子产品，从而增强了可伸缩设备的功能。将一个弹性体的膜融合到第二个的表面上，结合了两个弹性体的有利表面和散装特性。此外，形成两个弹性体之间界面的材料是一个关键的协同元素，将被利用以有利地影响膜表面上可拉伸材料和设备的功能。 该程序还将使用低成本，基于解决方案的可扩展方法来开发高电导性和可拉伸的织物和纤维来推动基于纺织品的可穿戴设备，该方法可以集成高电导率，同时保持纺织品的柔软，可拉伸性能。 新的可拉伸和导电纺织品将用于探索各种创新的新设备，例如在衣服中集成的可拉伸布线，连接设备，基于纤维的应变传感器，旨在检测身体运动并测量漏洞和呼吸的生命体征，以及可拉伸的光发光织物和纤维，以及设备功能的最终功能。
