New form of flexible electronic devices has recently emerged such as e-skins, wearable devices, and implantable systems. Especially, a flexible, and skin-attachable strain gauge sensor based on interconnected nanofibers was reported with discernible gauge factor for a flexible and highly sensitive pressure sensor. Here, we have presented the electrical circuit analysis for the distortion of mechanically interconnected nanohairs under physical stimulus of pressure. Considering the unique interlocking geometry, additional overlapping contact via pressure is proposed. In this way, we proposed a simple theory that can explain the observed electrical responses by employing the well-established friction law and electrical circuit analysis. Without involving a fitting parameter, the derived models can accurately describe the linear responses and the characteristic GF under dynamic situation and would be equally applied to other active nanoscale components exposed to a physical stimulus. |
