Tracking

When an unauthorized drone is being flown in a restricted airspace, the authorities understandably want to locate its operator. A new AI-based system may allow them to do so, succeeding where other technologies fail.

Currently the only way of getting stable video of flying insects involves tethering them in place – which some people would say isn't "flying" at all. Now, French scientists have developed a camera platform that moves through the air with the insect.

Flexible robotic surgical devices show a lot of promise, as they're able to move through delicate parts of the body without causing damage. Thanks to a new system, it could soon be cheaper, safer and easier to track where they are within the patient.

If you find existing fitness trackers a little plain and ordinary in their design, the new Amazfit X might be for you. It features a futuristic-looking curved touchscreen that wraps around your wrist, and a metal case for extra durability and polish.

Searching for sources of potentially harmful radiation isn't a job that most people would want – so why not get a drone to do it? Well, a team of Czech engineers is currently developing just such an aircraft.

If you were heading into a burning building, you'd probably want someone else to know your location within it at all times. German scientists have developed a system that's said to serve that purpose, for use by firefighters and other rescue workers.

When someone is recovering from surgery, they're typically encouraged to go for walks down the hospital hallways. Scientists have now found that by repurposing an existing device, it's possible to ascertain how much patients are heeding that advice.

Fitbit remains one of the most recognizable brands in health and fitness wearables, and it just launched its first new hardware product for more than six months: the GPS-enabled, Spotify-ready Fitbit Charge 4.

Wearables continue to get smaller, cheaper, and more capable, and the latest to enter the fray is the Wyze Band. For a mere US$25 you get just about everything you could want from a compact fitness tracker.

You may remember the smart jacket that Google and Levi's launched under the Project Jacquard umbrella – an initiative to add extra smarts to clothing. Now there's a new Jacquard product on sale in the form of smart insoles developed with Adidas.

It's definitely annoying when you're trying to swat a mosquito that's flying around a room, but you lose track of where it is. Bzigo is designed to help, as it optically-tracks mozzies and then highlights them with an eye-safe laser.

Although many scuba divers utilize wearable computers to track dive stats, those devices can't record an actual map of the underwater route that the user travelled. The newly-developed Brizo, however, is claimed to do exactly that.
