​When it comes to the continuous monitoring of people's vital signs, the rigid electrodes that are typically adhered to the skin can be uncomfortable, awkward, and a cause of skin irritation. That's where a new soft, flexible, wireless monitor is designed to come in.

​According to the American Heart Association, about one third of Americans can't estimate their daily sodium intake. If someone has a condition such as hypertension, obesity or diabetes, then knowing the correct figure is important – which is why scientists have developed an oral sodium sensor.

Australia is looking into equipping soldiers with a personal "black box" that will act as a combination data recorder and emergency beacon under a AU$700,000 (US$567,000) contract by the Department of Defence to develop the device called the "Flight Recorder."

For a wearable electronic sensor to be truly practical it would need to be comfortable when worn for extended periods of time. A team at the University of Tokyo has now developed a breathable nanoscale mesh that can be safely worn for a week without causing any skin irritation.

Our love affair with technology is leading to a whole lot of environmental problems, including a growing stockpile of discarded devices. What if there was a way for our unwanted electronics to break down so we wouldn't even need to think about the environmental impact of disposing of them?

Wearables don't always come in the forms of smartwatches​ and fitness trackers​. One subgenre is wellness wearables, which promise to do things like manipulate your mood or teach you to meditate. We took a handful for a test-drive.

The follow-up to one of the most unique wearables to date, Thync Relax is a more consumer-friendly take on the original's brain-zapping, mood-shifting focus. But what was lost in the process?

New research shows it wouldn't take much tweaking for activity trackers and other wearables to be able to also detect when we're getting sick.​

From temporary tattoos that track your blood alcohol level, to a paper skin that responds to stimuli, it's no stretch to realize that flexible electronics will be a big part of technology going forward. Adding yet another option to this field is a clear, conductive film made by mini jet engines.

​​If you don't like the thought of bugs crawling all over you, then you might not like one possible direction in which the field of wearable electronics is heading. Scientists recently showcased their new Rovables robots, which are tiny devices that roam up and down a person's clothing.

The British MoD has unveiled a new wearable sensor technology designed to keep track of squaddies and prevent friendly fire incidents. The Dismounted Close Combat Sensors (DCCS) system will allow commanders to track troops without GPS, while providing better situational awareness.

University of Washington engineers have produced a unique method to communicate with low-power, electronic devices such as brain implants and smart contact lenses by converting Bluetooth signals into Wi-Fi.
