Acoustic gunshot sensors help speed treatment of shooting victims

Acoustic gunshot sensors have been pinpointing shooting scenes and victims for years. The tech can be found in around 90 US cities in total. Meanwhile, the American military has been using it to track down the source of gunshots on the battlefield since 2011. But, the effectiveness of the sensors in saving the lives of […]

Super-thin edible sensors can monitor food temperature

Biomaterials that are rigid in form but able to degrade safely are everywhere. You can find tech like this in medical implants, environmental sensors and wearable, disposable devices. What’s harder to do, though, is to make sensors that you can digest. That’s exactly what Swiss researchers in Zurich have created, though: a thin, edible sensor […]

A Danish town has been using Bluetooth sensors to track traffic patterns

Enlarge / Who needs connected cars when almost all of us drive around emitting Bluetooth signals? (credit: dion gillard @flickr) One big promise of the connected car revolution has been the potential to help clear up traffic problems. When every vehicle and traffic signal is connected to the cloud, municipalities and local governments should be […]

One picture shows why self-driving cars are loaded with all kinds of sensors

MIT Technology Review Autonomous cars often proudly claim to be fitted with a long list of sensors—cameras, ultrasound, radar, lidar, you name it. But if you’ve ever wondered why so many sensors are required, look no further than this picture. You’re looking at what’s known in the autonomous-car industry as an “edge case”—a situation where […]

Ambient light sensors can be used to snoop on us while we’re web browsing

There are more ways to access your data than by exploiting the various software vulnerabilities and hardware bugs that we seem to hear about on a daily basis. Our gadgets actually have all kinds of weaknesses that could allow nefarious parties to steal our information, and some of them are things we’d probably never consider. […]

MasterCard adds fingerprint sensors to payment cards

Our fingerprints are quickly replacing PINs and passwords as our primary means of unlocking our phones, doors and safes. They’re convenient, unique, and ultimately more secure than easily guessed or forged passwords and signatures. So it makes sense that fingerprint sensors are coming to protect our credit and debit cards. MasterCard is testing out new […]

Camera sensors that see in only moonlight are coming to self-driving cars

The first high-sensitivity camera sensor could be coming to cars as early as 2018. On Wednesday, Sony announced the commercialization of the industry’s first high-sensitivity CMOS sensor that is capable of seeing in only moonlight. The IMX390CQV is a 2.45-megapixel camera designed specifically for driving. The minimal megapixel design allows each pixel to gather more light, […]
