Recent technologies on wearable devices and skin-mountable sensors are increasingly versatile with development of electronics technology and need of useful applications. Desirable skin-attachable sensors should have primary requirements such as strong adhesion, stable signal detection, and comfort. In this paper, we report a skin-attachable, reusable, stretchable, and large area covering surface electromyography(EMG) sensor. Sensor consists of serpentine structures referred as interconnects and frames which have different width and radius of curvature to change stiffness and compliance. The sensor enables simultaneous surface EMG signal detection from multiple muscles and control device for home electronics with the detected EMG signals.
