Nanorod LEDs could make multifunctional displays
Nanorod LEDs could make multifunctional displays 13.02.2017 - 23:27

Cell phones and other devices could soon be controlled with touchless gestures and charge themselves using ambient light, according to researchers at the University of Illinois and Dow Electronic Materials. Made of nanorods arranged in a thin film, LEDs arrays that can both emit and detect light could enable new interactive functions and ...



Chip to secure wireless chargers against counterfeit
Chip to secure wireless chargers against counterfeit 13.02.2017 - 23:24

To resolve the problem of counterfeit wireless chargers - which could cause power surges that fry a device’s circuitry – researchers from MIT’s Microsystems Technology Laboratories have built a chip that blocks attempts to wirelessly charge a device’s battery unless the charger first provides cryptographic authentication....



Software package allows power supply designers to get smart
Software package allows power supply designers to get smart 13.02.2017 - 23:20

Starting from a few specifications, such as required power or the entry and exit voltages, SmartCtrl – a program developed by the Universidad Carlos III de Madrid (UCM) – is said to provide those designing electronic power converters with a predefined map of solutions. This, say the developers, accelerates design work as engin...



‘Keep alive’ device draws power from sensor output
‘Keep alive’ device draws power from sensor output 08.02.2017 - 23:37

A low-cost chip developed at the University of Bristol is said to extend battery life in sensors; in some cases, by more than 10 times. The patent pending UB20M voltage detector is a ‘keep-alive’ device which, when combined with a suitable sensor, is said to eliminate standby power by enabling zero-power sensing and listening. The...



All digital PLL said to outperform comparable solutions
All digital PLL said to outperform comparable solutions 08.02.2017 - 23:34

Imec, Holst Centre and Rohm have described an all-digital phase-locked loop (ADPLL) for IoT radio transceivers at ISSCC 2017 in San Francisco. According to the partners, a PLL is not only one of the major power consumers in a radio, but can also take up to 30% of the radio area. In contrast, the ADPLL occupies just 0.18mm2 in a 40nm CMOS proc...



Plastic NFC tag to communicate with smartphones
Plastic NFC tag to communicate with smartphones 08.02.2017 - 23:27

imec, Holst Centre and Cartamundi claim to have demonstrated the first thin film tag on plastic, compatible with the near field communication (NFC) barcode protocol – a subset of ISO14443-A – which is available as a standard in many commercial smartphones. “Making a plastic electronics device compatible to the ISO standard o...



Solitons form a new field of electronics
Solitons form a new field of electronics 08.02.2017 - 23:23

Self-reinforcing solitary wave packets called solitons could achieve a more stable transmission of information, according to scientists at the Centre for Artificial Low Dimensional Electronic Systems (CALDES), within Korea's Institute for Basic Science (IBS). Their experiments and models are said to pave the way to a new field of electronics...



Op amp said to ‘set the standard’
Op amp said to ‘set the standard’ 08.02.2017 - 23:12

In a move which it claims sets the standard for precision amplifiers, Texas Instruments has launched the OPA388, which it describes as the first operational amplifier to offer zero-drift and zero-crossover technology. This, it continues, allows the device to maintain high precision across the entire input range in such applications as test an...



Time synchronisation for energy efficient sensors
Time synchronisation for energy efficient sensors 24.01.2017 - 23:53

One of the key ideas behind the IoT is the use of sensor networks to gather data. But when there may be thousands of sensors in a network, each sensor needs to be as low cost as possible. However, low cost sensors often have limited energy and computing capacities, so making the most of these limited resources is important and Austrian resear...



Topological photonic crystal made of silicon
Topological photonic crystal made of silicon 24.01.2017 - 23:41

A new principle, in which electromagnetic waves, including light, can propagate on the edge of a 2D photonic crystal without being scattered, has been developed by researchers from Japan’s International Center for Materials Nanoarchitectonics (MANA) and the National Institute for Materials Science (NIMS). It was known that scattering of...
