Conductive hydrogel could find use in soft robotics and more

Ordinarily, if you want to build a device that’s highly electrically conductive, you have to use rigid metals. Now, however, scientists at Carnegie Mellon University have created a soft and flexible material that fits the bill.Continue ReadingCategory:… Continue reading Conductive hydrogel could find use in soft robotics and more→

More secure two-factor ID system requires users to make faces

Although facial ID verification tech may seem pretty impressive, it can be thwarted. An experimental new system is claimed to be more foolproof, by requiring users to make specific facial movements.Continue ReadingCategory: Good Thinking, LifestyleTags… Continue reading More secure two-factor ID system requires users to make faces→

Security keypad designed to thwart thieves – by being transparent

In order for a thief to bypass a security system’s interface, they generally have to see that interface in the first place. That’s why Swiss scientists have designed an access code keypad which is completely transparent.Continue ReadingCategory: Good T… Continue reading Security keypad designed to thwart thieves – by being transparent→

“Growing” heart valve implant would never have to be replaced

When a child receives a replacement heart valve, the device doesn’t grow along with them. This means it will have to be surgically replaced, multiple times. Such may not be the case, however, with a new valve that’s currently in development.Continue Re… Continue reading “Growing” heart valve implant would never have to be replaced→

Pressure-sensing cap designed to guarantee a proper helmet fit

Even though a properly-fitted sports helmet is vital to avoiding brain injuries, the fitting process is still largely a subjective one. A newly designed pressure-sensitive cap, however, could objectively ensure that each athlete gets the right helmet.C… Continue reading Pressure-sensing cap designed to guarantee a proper helmet fit→

VR wristband tracks finger-taps via vibrating wrist bones

Currently, if you want a VR setup to “know” what your individual fingers are doing, you either have to wear special gloves or place your hands directly in front of a camera. A new system, however, keeps tabs on the fingers via a simple wristband.Contin… Continue reading VR wristband tracks finger-taps via vibrating wrist bones→

Analysis of speckled laser light could help prevent heart attacks

Heart attacks often occur when plaque deposits break off of blood vessel walls, subsequently blocking arteries that carry oxygen to the heart. A new imaging process could identify those unstable deposits, allowing them to be treated before they rupture… Continue reading Analysis of speckled laser light could help prevent heart attacks→

Fruit n’ veg film designed to detect pesticide residue

Fresh produce suppliers may say there’s no pesticide residue on their fruits and veggies, but … are they telling the truth? Store workers could soon be able to check, using an inexpensive stick-on film.Continue ReadingCategory: ScienceTags: ITMO Univer… Continue reading Fruit n’ veg film designed to detect pesticide residue→

Light and flexible Litelok is back, in beefier Core incarnation

Back in 2015, former aeronautical engineer Neil Barron presented his Litelok as a lighter, more flexible alternative to bicycle U-locks. His company is now offering a rougher, tougher version, called the Litelok Core.Continue ReadingCategory: Bicycles,… Continue reading Light and flexible Litelok is back, in beefier Core incarnation→
