Carbon nanotube (CNT) film-based photo-thermoelectric (PTE) imagers are crucial for multimodal non-destructive inspection but face challenges in achieving high response intensity for wireless data logging. Here, the authors develop chemically enriched PTE imagers using semiconducting-separated CNT films, achieving enhanced response intensity and noise reduction, enabling efficient remote and on-site inspections.
