可拉伸的无线健康监测贴片，用于评估心率、血氧饱和度、紫外线暴露和皮肤颜色。材料、力学和电子设备设计方面的最新进展正在迅速为具有“皮肤”特性的健康监测技术奠定基础，这些技术可以选择长期（数周）与表皮结合。由此产生的生理传感能力大大超过了传统的硬电子系统，比如手腕上的可穿戴设备，因为它具有亲密的皮肤界面。然而，这类新兴设备的大多数例子都需要电池和/或硬连线连接才能运行。这里报道的工作介绍了无电池和完全无线模式的有源光电系统，例如设计用于皮肤多波长光学表征的薄可拉伸平台。磁感应耦合和近场通信（NFC）方案为多色发光二极管供电，并以与标准NFC支持平台（如智能手机和平板电脑）兼容的方式从集成光电探测器提取数字数据。监测心率和动脉血流的时间动态，定量组织氧合和紫外线剂量法，以及对皮肤进行四色光谱评估等方面的例子都证明了这些概念的多功能性。研究结果对医院护理和家庭诊断都有潜在的相关性。
Stretchable, wireless health monitoring patches to evaluate heart rate, blood oximetry, UV exposure, and skin coloration. Recent advances in materials, mechanics, and electronic device design are rapidly establishing the foundations for health monitoring technologies that have “skin-like” properties, with options in chronic (weeks) integration with the epidermis. The resulting capabilities in physiological sensing greatly exceed those possible with conventional hard electronic systems, such as those found in wrist-mounted wearables, because of the intimate skin interface. However, most examples of such emerging classes of devices require batteries and/or hard-wired connections to enable operation. The work reported here introduces active optoelectronic systems that function without batteries and in an entirely wireless mode, with examples in thin, stretchable platforms designed for multiwavelength optical characterization of the skin. Magnetic inductive coupling and near-field communication (NFC) schemes deliver power to multicolored light-emitting diodes and extract digital data from integrated photodetectors in ways that are compatible with standard NFC-enabled platforms, such as smartphones and tablet computers. Examples in the monitoring of heart rate and temporal dynamics of arterial blood flow, in quantifying tissue oxygenation and ultraviolet dosimetry, and in performing four-color spectroscopic evaluation of the skin demonstrate the versatility of these concepts. The results have potential relevance in both hospital care and at-home diagnostics.
