Soft electronic devices that can acquire vital signs from the human body represent an important trend for healthcare. Combined strategies of materials design and advanced microfabrication allow the integration of a variety of components and devices on a stretchable platform, resulting in functional systems with minimal constraints on the human body. In this presentation, I will demonstrate a wearable multichannel patch that can sense a collection of signals from the human skin in a wireless mode. Additionally, integrating high-performance ultrasonic transducers on the stretchable platform adds a new third dimension to the detection range of conventional soft electronics. Ultrasound waves can penetrate the skin and noninvasively capture dynamic events in deep tissues, such as blood pressure and blood flow waveforms in central arteries and veins. This stretchable platform holds profound implications for a wide range of applications in consumer electronics, sports medicine, defense, and clinical practices.
基于柔性电子设备获取人体生命特征信号是医疗保健设备发展的一个重要趋势。结合材料设计和先进的微加工技术，各种组分和器件可集成在可拉伸的平台上，从而实现对人体的约束最小的健康检测功能系统。在本演讲中，我将介绍一种可穿戴的多通道贴片，该贴片以无线模式感应来自人体皮肤的一系列信号。此外，在可伸缩平台上集成了高性能超声换能器，从而拓宽了传统柔性电子器件的三维空间探测范围。超声波可以穿透皮肤并且无创伤地捕获深层组织中的动态生理活动，例如中央动脉和静脉中的血压和血流波形。此类可伸缩的平台对商品化电子产品、运动医学、国防和临床等领域均具有深远的影响和意义。
