Ultra-Flexible Organic Near-Infrared Photodetectors with Deformable Durable Dark Current for Photoplethysmogram Sensors |
| 초록 |
Near-infrared (NIR) photodetectors have applications in optical, chemical, and biomedical sensors. Among these diverse applications, the NIR photodetector can be used as a key component in the field of photoplethysmography (PPG) sensors. In particular, the ultra-flexible near-infrared organic photodetectors (NIR-OPDs) are attracting attention from academia and industry as a PPG sensor with outstanding flexibility and is suitable for skin. In this study, we report on NIR-OPDs with high deformation durability and performance using an organic bulk heterojunction (BHJ) layer. A NIR-OPDs with low dark current and high responsivity was fabricated using the BHJ combination composed of PTB7-Th:Y6. The optimized NIR-OPD showed a high specific detectivity of 2.2 x 1012 Jones at 800 nm. And finally, we demonstrated an ultra-flexible NIR-OPD by constructing the device on a parylene substrate. |
