A body area sensor network (bodyNET) is a collection of networked sensors that can be used to monitor human physiological signals. For its application in next-generation personalized healthcare systems, seamless hybridization of stretchable on-skin sensors and rigid silicon readout circuits is required. Here, we report a bodyNET composed of chip-free and battery-free stretchable on-skin sensor tags that are wirelessly linked to flexible readout circuits attached to textiles. Our design offers a conformal skin-mimicking interface by removing all direct contacts between rigid components and the human body. Therefore, this design addresses the mechanical incompatibility issue between soft on-skin devices and rigid high-performance silicon electronics. Additionally, we introduce an unconventional radiofrequency identification technology where wireless sensors are deliberately detuned to increase the tolerance of strain-induced changes in electronic properties. Finally, we show that our soft bodyNET system can be used to simultaneously and continuously analyse a person’s pulse, breath and body movement.

人体区域传感器网络（bodyNET）是可用于监视人体生理信号的联网传感器的集合。对于其在下一代个性化医疗系统中的应用，需要可拉伸的皮肤传感器与刚性硅读出电路的无缝混合。在这里，我们报告了一个bodyNET，该bodyNET由无芯片和无电池的可拉伸皮肤传感器标签组成，这些传感器标签与连接到纺织品的柔性读出电路无线链接。我们的设计消除了刚性组件与人体之间的所有直接接触，从而提供了仿形的皮肤模拟界面。因此，该设计解决了软皮设备与刚性高性能硅电子产品之间的机械不兼容问题。此外，我们引入了一种非常规的射频识别技术，其中故意使无线传感器失谐，以提高应变引起的电子特性变化的容忍度。最后，我们证明了我们的softbodyNET系统可用于同时连续地分析一个人的脉搏，呼吸和身体运动。
