Carbon-based, Ultraelastic, Hierarchically Coated Fiber Strain Sensors with Crack-controllable Beads |
| 초록 |
Fiber-based electronics or textronics are spotlighted as a promising strategy to develop wearable devices for conformable machine-human interface and ubiquitous healthcare systems. We have prepared a highly sensitive fiber strain sensor with a broad range of strain by introducing a single active layer onto the fiber. In contrast to other metal-based textronics, our hierarchical fiber sensors are based on coating carbon-based nanomaterials with responsive microbeads onto elastic fibers. Utilizing the formation of uniform cracks around the beads, the device performance was maximized by adjusting the number of beads in the carbon-coating layer. Our fiber sensors were repeated tested more than 5000 times, exhibiting excellent cyclic responses to on/off switching behaviors. For practical applications, the hierarchical fiber sensors were sewed into electrical fabric bands to monitor waveforms of pulsations, respirations, and various postures of level of bending a spinal cord. |
