Although hearing aids do make life easier for many people, their limited battery life can be problematic. Scientists have set about addressing that shortcoming, by designing a hearing aid that requires no batteries.
-
Swimming is one of those sports in which stopping to check a smartwatch can be quite disruptive. Because of this, we've recently seen a number of performance-tracking goggles. One of the newest, known as Holoswim, is now on Kickstarter.
-
Although there are now a number of devices that generate electricity via movement, most of them only work in dry environments. A new one, however, also works underwater – meaning it could be used in implants, or wearables that get exposed to sweat.
-
Rice University researchers have produced a "smart" shirt that uses interwoven carbon nanotube fibers to provide steady electrical contact with the skin, allowing for ongoing gathering of data on heart activity.
-
Although we do keep hearing about flexible wearable electronics, most such devices are still powered by rigid batteries that regularly need to be recharged. An experimental new battery, however, is soft, stretchable, and powered by human sweat.
-
A new type of wearable leverages the surprisingly large sweat output of the fingertips to generate electricity when the user is sedentary or even sleeping, providing a potentially round-the-clock source of power.
-
A new design for a so-called electronic skin addresses one of the technology's key shortcomings so far, by taking inspiration from the sweat pores in human skin to prevent the accumulation of moisture that can compromise performance.
-
It looks like something straight out of dystopian sci-fi, but then here we are. Biotlab has presented a neck-mounted wearable that provides you with a range of magnetic face shields, and a personal supply of HEPA-filtered, UV-sterilized air.
-
It's been a while since we saw a hardware update to the Vive line, but HTC has made up for it by launching two 5K-resolution virtual reality headsets at the same time: the PC-connected Vive Pro 2, and the standalone Vive Focus 3.
-
Autonomous vehicles and robots navigate with sensors and cameras – but visually-impaired people still get by with canes and guide dogs. Now, engineers have developed a wearable AI system that tracks obstacles and describes a person’s surroundings.
-
There are energy sources all over the place, if you know where to look. Researchers at CUHK have now designed new modular nanogenerators that can harvest energy from various different types of motion, such as ocean waves or a person's body movements.

The Fitbit Sense is the flagship device in the Fitbit range, the top device from one of the top names in wearables – and we've been trying to figure out whether or not it's worth the US$299.95 that you'll have to pay to get hold of one.
