To improve efficiency, it is necessary to characterize and reduce flow separation on curved surfaces. To this end, researchers have now developed a flexible, thin film microelectromechanical system-based airflow sensor that can be utilized to measure complex, three-dimensional flow separation in curved walls for high-speed airflows.

Thus far, however, IR detectors have relied on bulky (and expensive) materials and technologies. A team of scientists has now succeeded in developing a cost-effective miniaturization process for IR spectrometers based on a quantum dot photodetector, which can be integrated on a single chip.
