Taking greenhouse gas analysis on the road, er, rails

Research-grade air quality sensors are costly—around $40,000. For cities trying to monitor their greenhouse gas emissions, the cost may limit the number of sensors they can install and the data they can collect.

Terraced graphene for ultrasensitive magnetic field sensor

National University of Singapore physicists have developed a sensitive two-dimensional (2-D) magnetic field sensor, which can potentially improve the detection of nanoscale magnetic domains for data storage applications.

Having an eye for colors: Printable light sensors

Cameras, light barriers, and movement sensors have one thing in common: They work with light sensors that are already found in many applications. In future, these sensors might also play an important role in telecommunications, ...

Slow light to speed up LiDAR sensors development

Quicker is not always better, especially when it comes to a 3-D sensor in advanced technology. With applications in autonomous vehicles, robots and drones, security systems and more, researchers are striving for a 3-D sensor ...

A wearable vibration sensor for accurate voice recognition

A voice-recognition feature can be easily found on mobile phones these days. Oftentimes, we experience an incident where a speech recognition application is activated in the middle of a meeting or a conversation in the office. ...
