Dirt. For millennia, the dark, rich soil underlying farms and gardens worldwide has been central to human survival. It’s also a lot more complex than it looks. Within every clump of soil lies an ...

MIT researchers have created a quantum sensor that can measure multiple physical quantities at high-resolution. The sensor is made from so-called nitrogen-vacancy centers in diamonds, where a carbon ...

Fig. 1. Strip-type deformation sensors. One ply of cured carbon fiber/epoxy prepreg to be monitored is used as a thin, flexible sheet with optical fibers — one embedded in the upper surface and one in ...

Rather than building ever-larger Coriolis, vortex or ultrasonic sensors, engineers can use smaller measuring paths and combine their outputs to accurately measure flow in large-diameter pipelines.
