Nanowerk January 2, 2018 Researchers in Germany are developing a quantum sensor that will be able to precisely measure the tiny magnetic fields we can expect to see in the next generation of hard discs. The sensor itself is just slightly larger than a nitrogen atom, with a specially grown ultra-pure diamond crystal as a substrate. The combined nitrogen-vacancy center acts as the actual sensor. Using electron spin resonance spectroscopy, they can detect magnetic fields with nanometer accuracy, and determine their force opening an extraordinary range of applications. Potentially the sensor can be used to measure brain activity. Read […]

Ocean of Things Aims to Expand Maritime Awareness across Open Seas
Source: DARPA, December 6, 2017 DARPA’s Ocean of Things program seeks to enable persistent maritime situational awareness over large ocean areas by deploying thousands of small, low-cost floats that could form a distributed sensor network. Each smart float would contain a suite of commercially available sensors to collect environmental data—such as ocean temperature, sea state, and location—as well as activity data about commercial vessels, aircraft, and even maritime mammals moving through the area. The floats would transmit data periodically via satellite to a cloud network for storage and real-time analysis. The technical challenge lies in two key areas: float development […]
