AI skeleton key fingerprint fools 1 in 5 ID systems

Fingerprint authentication systems can be fooled by generic fingerprints created by artificial intelligence, according to the New York University Tandon. “These experiments demonstrate the need for multi-factor authentication and should be a wake-up call for device manufacturers about the potential for artificial fingerprint attacks,” said researcher Philip Bontrager. “Fingerprint-based authentication is still a strong way to protect ...

Meter-surface corrects chromatic abberation

A single-layer of nano-structures on the surface of optical elements can correct chromatic aberrations across the visible spectrum, from simple lenses to “the super-complex objectives with as many as 14 conventional lenses, used in high-resolution microscopes”, according to Harvard University which has developed the technique. It has been dubbed ‘metacorrection’, and relies on pillars whose ...

How MIT e-plane works

Earlier this week, engineers at MIT flew a plane by what they have dubbed ‘solid-state flight’. Instead of propellers or some form of jet engine, the scheme uses high voltage to accelerate ions in the air, and these, in-turn, accelerate molecules in the air. In this case, there are multiple accelerators – two columns of ...

CES: Plessey honoured for micro LED displays for AR

Devon-based chip fab Plessey has wonn US recognition for its GaN-on-silicon microdisplays – being named a ‘CES 2019 Innovation Awards Honoree’ in the exhibition’s embedded technologies category. The displays could offer a route to the high intensities needed for augmented reality googles that can be used outdoors – where the display has to compete with ...

Non-ITO transparent conductor vies for foldable display market

Heraeus Electronic Chemicals of Germany is promoting its Clevios HY E conductive film for foldable touchscreen use. It is a hybrid material, of silver nanowires (to raise conductivity) and conductive PEDOT polymers. “In tests, films coated with Clevios HY E have been folded more than 300,000 times with a bending radius of 1mm with no impairment ...

e-skin senses sideways force as well as direct force

An electronic copy of human skin can detect force, and the direction of that force. When griping with thumb and fingers, a robot hand using this could sense both the weight of an object and the force applied to it, allowing more sophisticated manipulation. “This technology puts us on a path to one day giving robots ...

Plasmonic receiver for last-metres mm-wave comms

Researchers at ETH Zurich have developed a plasmonic receiver that can convert millimetre waves directly into light for an optical fibre. “Our modulator is completely independent of external power supplies and, on top of that, extremely small so that it can, in principle, be mounted on any lamppost. From there, it can then receive data ...

ST takes MCU configuration tool to v5.0

STMicroelectronics has updated its STM32CubeMX microcontroller configuration software to v5.0. “With its modern multi-panel GUI that lets users visualise and do more without changing screen view, it makes optimising MCU configuration parameters easier and more comfortable,” said the firm, without explaining what multi-panel means in this context – this video might give some clues. It comes ...

Three phase EMC filters for motor drives

Schaffner is claiming to have created a milestone in three-phase filtering with “the most compact and most modern solution in the market today”. And then it said: “these filters are based on a new design structure, resulting in a significant footprint reduction and have their connection terminals integrated within the filter enclosure.” And then it ...

Electronica: Waterproof professional connectors for outdoor use

Lemo revealed waterproof versions of its right-angled Anglissimo connectors at Electronica last week. “This product is similar to what had been announced previously, but this time it’s an evolution of the product that make this solution watertight to IP68, meaning it can be used outdoors, under the rain, it can sustain water splash and short ...
