Highly Flexible Organic Nanofiber Phototransistors on a Textile Composite and Their Applications in Wearable Photosensors |
| 초록 |
For wearable smart electronics, flexible electronic devices are considered as key components. Flexible organic electronic devices with high mechanical stability have been prepared on various types of substrates. Textiles have been considered strong candidates as novel substrates for wearable electronics with high flexibility and stretchability for various applications. However, textile is hard to be utilized as the substrate of the electronic devices because of its high surface roughness. Herein, we report highly flexible phototransistors based on a textile/PDMS composite substrate and electrospun semiconducting nanofibers. The textile-based phototransistors showed stable device performance under extreme bending conditions (bending radius down to 0.75 mm and over 1,000 cycles). Finally, we demonstrated flexible 10×10 arrays of photosensors which can detect incident photonic signals with high resolution. Our results showed possibility of applications toward the wearable photosensors. |
