To perform wearable and continuous health monitoring, epidermal electronics for all kinds of sensing have been developed, yet neither organic nor inorganic materials‐based epidermal devices are able to perform the functions like signal collection, processing, transmission, or power supply. Here, a strategy is reported to build skin‐like hybrid integrated circuits (SHICs) with stretchable sensors and commercial chips for long‐term respiratory monitoring. It can independently perform signal acquisition, processing, converting, and wireless transmission with carrying power supply. Thermal theory model is established to characterize the breathing air's interaction with the sensor, which helps in signal analysis. Respiratory monitoring on human body is tested in diverse daily activities including exercising, dining, drinking, and sleeping with a custom‐developed phone application to record and display the respiratory signal. Results show that the SHIC is of high efficiency and accuracy to track the breath patterns continuously in both static and moving scenarios. Furthermore, the SHIC is a feasible and promising platform that can be extended with multiple sensors or actuators in individualized medical applications and physiological study.

面向面部的类似于皮肤的混合集成电路,用于连续呼吸监测

为了执行可穿戴和连续的健康监测,已经开发了用于各种传感的表皮电子设备,但是基于有机或无机材料的表皮设备均无法执行信号收集,处理,传输或电源之类的功能。在这里,据报道有一种策略可以构建具有可拉伸传感器和商用芯片的皮肤状混合集成电路(SHIC),以进行长期呼吸监测。它可以在带电源的情况下独立执行信号采集,处理,转换和无线传输。建立热学理论模型来表征呼吸空气与传感器的相互作用,这有助于信号分析。在各种日常活动中对人体呼吸监测进行了测试,包括锻炼,就餐,饮水,并与定制开发的电话应用程序一起睡觉,以记录和显示呼吸信号。结果表明,SHIC在静态和动态场景下都能高效,准确地连续跟踪呼吸模式。此外,SHIC是一个可行且有前途的平台,可以在个性化医疗应用和生理研究中扩展多个传感器或执行器。
