Will strong and fast-switching artificial muscle be feasible?

In the American action movie "Pacific Rim," giant robots called "Jaegers" fight against unknown monsters to save mankind. These robots are equipped with artificial muscles that mimic real living bodies and defeat monsters ...

Runners prefer the same pace, regardless of distance

Stanford University scientists have found that when recreational runners are left to their own devices and outfitted with a wearable fitness tracker, they prefer to run at the same calorie-saving pace, regardless of the distance ...

Color-sorting metalenses boost imaging sensitivity

Researchers have shown that newly designed pixel-scale metasurface lenses—flat surfaces that use nanostructures to manipulate light—can be used to make imaging sensors that are roughly three times more sensitive than ...

A new 3D printing frontier: Self-powered wearable devices

When most people think of wearable devices, they think of smart watches, smart glasses, fitness trackers, even smart clothing. These devices, part of a fast-growing market, have two things in common: They all need an external ...

Scientists create UV-enabled flexible wearable technology

To enable the development of wearable devices that possess advanced ultraviolet (UV) detection functions, scientists from NTU Singapore have created a new type of light sensor that is both flexible and highly sensitive.While ...

Signs of burnout can be detected in sweat

EPFL engineers, working in association with startup Xsensio, have developed a wearable system that can continually measure the concentration of cortisol—the stress hormone—in human sweat. Their device can eventually help ...
