Because of portability and flexibility, flexible wearable electronic devices will be increasingly used in today's human life. In this paper, mechanical analysis of paste process of wearable electronics to skin is carried out, and the skin comfort is judged by mechanical response of skin surface. Theoretical result of interface between flexible electronics and skin when sensors are of different shapes is obtained. Numerical calculation is carried out, and effects of geometric and physical parameters on skin stresses are investigated. It is found that for devices with the same width and thickness, the strip shape is more likely to cause skin discomfort than the circular shape. Conclusions in this paper provide theoretical basis for designing wearable electronics.

由于便携性和灵活性，柔性可穿戴电子设备将在当今人类生活中得到越来越多的使用。本文对可穿戴电子产品粘贴到皮肤上的过程进行了力学分析，并通过皮肤表面的机械反应来判断皮肤的舒适度。当传感器具有不同的形状时，获得了柔性电子设备与皮肤之间的界面的理论结果。进行了数值计算，并研究了几何和物理参数对皮肤应力的影响。已发现，对于具有相同宽度和厚度的设备，条形比圆形更容易引起皮肤不适。本文的结论为设计可穿戴电子设备提供了理论基础。
