Article Synopsis
- Recent advances in bio-inspired navigation focus on skylight polarization, which has potential applications in orientation sensors, but machine learning requires extensive datasets for training.
- A new dataset was created from a long-term setup using a Division-of-Focal-Plane polarization camera to collect polarimetric images of the sky, ensuring data diversity across various weather conditions.
- This two-month dataset, featuring manually annotated images captured at 10-minute intervals with varying exposure times, is now publicly available to support further research in this field.
We report improved sensitivity to NO, NO₂ and NH₃ gas with specially-designed AlGaN/GaN high electron mobility transistors (HEMT) that are suitable for operation in the harsh environment of diesel exhaust systems. The gate of the HEMT device is functionalized using a Pt catalyst for gas detection. We found that the performance of the sensors is enhanced at a temperature of 600 °C, and the measured sensitivity to 900 ppm-NO, 900 ppm-NO₂ and 15 ppm-NH₃ is 24%, 38.
