Thin-film electronic devices can be integrated with skin for health monitoring and/or for interfacing with machines. Minimal invasiveness is highly desirable when applying wearable electronics directly onto human skin. However, manufacturing such on-skin electronics on planar substrates results in limited gas permeability. Therefore, it is necessary to systematically investigate their long-term physiological and psychological effects. As a demonstration of substrate-free electronics, here we show the successful fabrication of inflammation-free, highly gas-permeable, ultrathin, lightweight and stretchable sensors that can be directly laminated onto human skin for long periods of time, realized with a conductive nanomesh structure. A one-week skin patch test revealed that the risk of inflammation caused by on-skin sensors can be significantly suppressed by using the nanomesh sensors. Furthermore, a wireless system that can detect touch, temperature and pressure is successfully demonstrated using a nanomesh with excellent mechanical durability. In addition, electromyogram recordings were successfully taken with minimal discomfort to the user.

具有纳米网格的无炎症，透气，轻便，可拉伸的皮肤电子设备

薄膜电子设备可以与皮肤集成在一起，以进行健康监测和/或与机器连接。当将可穿戴电子设备直接应用到人体皮肤上时，非常需要微创。然而，在平面基板上制造这种皮肤上电子器件导致透气性受限。因此，有必要系统地研究它们的长期生理和心理影响。作为无基材电子产品的演示，我们在此展示了成功制造的无炎症，高透气性，超薄，轻巧和可拉伸的传感器，该传感器可以长时间层压在人体皮肤上，并通过导电纳米网实现结构体。一项为期一周的皮肤补丁测试表明，使用纳米网状传感器可以显着抑制由皮肤上传感器引起的炎症风险。此外，使用具有出色机械耐久性的纳米网成功演示了可以检测触摸，温度和压力的无线系统。另外，成功地采集了肌电图记录，而给用户带来最小的不适感。
