Cover illustration demonstrates dual-band organic photodetectors enabling bio-sensing in wearable technology, suggesting significant applications.
Flexible Sensor This cover illustrates an ultra-flexible dual-band organic photodetector for voltage-switchable visible and near-infrared light detection. The 5.6-µm-thick device attached on a human finger successfully acquires pulse wave from visible and near-infrared components, respectively, demonstrating correlation with peripheral oxygen saturation. This work highlights the potential of dual-band organic photodetectors for wearable bio-sensing applications.
