Sensor

Engineers at UC Davis have developed a new radar sensor that can pick up movements just 100th the width of a human hair. Better yet, the sensor itself is only the size of a sesame seed and is energy efficient.

Researchers have developed a tiny sensor that monitors the freshness of protein-rich foods like meat, chicken and fish in real time and sends the data to your smartphone. The device has the potential to transform food safety and security worldwide.

Monitoring extreme environments requires a sensor continues to work in high temperatures. Now, researchers have developed a piezoelectric sensor that operates reliably at the temperature of erupting mafic lava, the hottest type of lava on Earth.

Researchers have created cutting-edge graphene sensors to produce an interface that allows for accurate robotic control using thought alone. The development has positive implications for healthcare and a range of other industries.

A team of engineers has developed a new type of camera that can detect radiation in terahertz wavelengths. This new imaging system can see through certain materials in high detail, which could make it useful for security scanners and other sensors.

Blind corners have long troubled drivers, but researchers have now developed a holographic camera technology that can peer around corners by reconstructing scattered light waves, quickly enough to spot fast-moving objects like cars or pedestrians.

Engineers at MIT’s CSAIL have developed a smart carpet that can accurately estimate a person’s movements or body pose without needing cameras. The system could be useful for exercise feedback, monitoring falls, or tracking for VR and gaming.

No matter how good we humans have made something, chances are nature did it better. Rather than compete, scientists have now tapped into a natural sensor with the Smellicopter, a drone that uses an antenna from a live moth to sniff out its targets.

Scientists have fashioned graphene into microscopic balloons they say can distinguish between different kinds of noble gases, by measuring how long the gas takes to escape through tiny perforations in the surface of the balloons.

Researchers at the University of Washington have developed a tiny new sensor that can be carried around on a small drone or even the back of an insect – and then dropped on demand to track the environment for years at a time.

Scientists have developed what they claim is the smallest particle sensor in the world, designed specifically to detect harmful pollutants and offer a highly localized picture of air quality by being integrated into wearables and mobile devices.

To create a great smartphone camera, first you need a great mobile camera sensor, and Samsung just unveiled a new 50-megapixel, 1/1.31-inch Isocell GN1 sensor – a component that should find its way into future Samsung phones before too long.
