Last year we heard about an "electronic skin" developed at City University of Hong Kong, which delivers tactile sensations to wearers. The university has now gone one better, with an e-skin that both senses and reproduces users' touches.

While technology is making strides in absorbing our eyes and ears in virtual worlds, it’s harder to engage senses like touch. Engineers have now developed WeTac, a thin, wearable electronic "skin" that provides tactile feedback to users in VR and AR.

City University of Hong Kong researchers have accidentally discovered a first-of-its-kind high-entropy alloy that retains its stiffness, and actually becomes springier, instead of softening at high temperature. No other known metals behave this way.

As if the ray fishes weren't unusual enough already, it turns out that their sperm is also unique. Scientists have now created a robot inspired by those sperm, which may someday lead to smaller descendants that swim within the human body.

When someone has a problematic skin condition, the affected skin is typically either stiffer or softer than normal. A new sensor has been shown to detect such differences, potentially allowing doctors to diagnose problems more quickly and easily.

Nobody likes needles, but they’re a necessary evil. Microneedle patches are emerging as a painless alternative, and now researchers in Hong Kong have developed a new version of the tech that’s made of ice, for easier manufacture and use.

Although wing-flapping micro-drones do already exist, the things tend to be quite fragile – and thus not ideally suited to real-world use. An experimental new one, however, utilizes a softer mechanism for greatly enhanced durability.

Last year gravitational waves were detected from a massive black hole collision. But now astrophysicists propose a new explanation: a collision of two boson stars – hypothetical, invisible objects that could help untangle the mystery of dark matter.

Diamond is a famously hard material, but now scientists have managed to stretch it further than ever before. Why? Stretching nanoscale samples changes their electronic and optical properties, which could open up a new world of diamond devices.

Scientists at the City University of Hong Kong have developed a new type of spray-on coating they say can give regular objects the capabilities of magnetically controlled robots, with particular potential in biomedical applications.
-
When natural ocean shoreline is replaced by an artificial seawall, a lot of precious intertidal habitat is lost. A new study, however, indicates that by covering those walls with specially designed tiles, a substitute habitat can be created.

An international team of scientists has created a new type of solar flow battery that’s efficient and long-lasting. The device is made up of a silicon/perovskite tandem solar cell, paired with a redox flow battery, with organic chemical electrolytes.
