Adaptive Metalen: A Powerful Replica of The Human Eye

Following the contemporary progress in meta-surfaces, a group of researchers from Harvard SEAS (School of Engineering and Applied Science) has leveraged upon this development to produce a photoelectric artificial ‘eye’. Seeing that focus, astigmatisms and image shift are core constituents of advanced optical systems.

These Scientists were able to establish that such optical components as lenses could administer a better performance if reassembled into – a silicon metalen mounted on an ultra-slim polymer film. Termed the “Adaptive Eye” – this 30 micrometers-thick metalen, just like the human eyes automatically adjust its focus in real-time.

In addition to regulating focus, the silicon nanostructure is designed with more powerful features than the human eyes such as image shift and astigmatism. Achieving an advanced optical zoom, transfixing autofocus, and better image stabilization.

The ‘Metalen Eye’ is expected to conveniently succeed in the sphere of optical lens developments used in eyeglasses, cameras, cell phones, microscopes, telescopes and other wearable technologies such as augmented and virtual reality devices.

According to one of the Researchers – Federico Capasso, a condition of merging both the semiconductor and lens manufacturing industries had to be met, in order to see to its success.

In his words, he stated that;

“This research provides the possibility of unifying two industries, semiconductor manufacturing, and lens-making, whereby the same technology used to make computer chips will be used to make metasurface-based optical components, such as lenses.”

Originally initiated by Researcher Alan She – of the Harvard SEAS, while been fully endorsed by the National Science Foundation and the Air Force Office of Scientific Research. The ideas behind this neoteric development date back to the mid-1990s, a time at which the wavelength of light was more sparse than the sizes of the semiconductors manufactured.

Subsequently, these researchers had to come up with an algorithm to reduce the file size to ensure it is compatible with the current technology used for integrated circuits.

However, the development of the ‘Metalen Eye’ revolves majorly around the idiosyncrasies of present-day technological advancement such as AI, Machine-learning and Deep-learning fused together with nanotechnology. Having that this investigation was jointly conducted at the Center for Nanoscale Systems (CNS).

Toyota Debuts The First Solar-Powered Electric Car That Never Needs Charging

Just recently Toyota announced the launch of a new solar-powered vehicle that never needs charging. By means of a highly flexible, ultra-slim and super-efficient solar panel affixed at the top of the car, this super-vehicle is believed to able to run for about 56 kilometers without a recharge, giving it an edge over conventional electric cars, hybrid vehicles, and hydrogen-powered automobiles. Consequently eradicating the need to plug in your Electric Vehicle (EV) intermittently and embrace the world of electric cars that recharges itself on the go.

Following an interview with Toyota’s Project Manager – Koji Makino by Bloomberg, who confirmed that this electric car is one of a kind. Adding that; 

“The solar car’s advantage is that — while it can’t drive for a long-range — it’s really independent of charging facilities,”

Dubbed a unique car that could “run for ever” by Bloomberg, this technology comes to life through a partnership agreement between Toyota, Sharp, and the New Energy and Industrial Technology Development Organization (NEDO) of Japan. 

Notably, the Toyota Prius-prototype’s build comes with a 0.03 mm thick solar-panel sheet that spreads all over the hood and from the rear hatchback through to the roof. Providing enough reception to store a tremendous amount of solar energy. These powerful solar cells together with a durable battery of immense capacity are designed to house enough electrical energy to power the car up to 35 miles at night. Which is about 9 times more efficient than the current model at hand. 

Hence the director at the solar energy systems division of NEDO – Mitsuhiro Yamazaki, describes the experimental Toyota Prius solar car as being able to be driven to as far as 50 kilometers each day, for four days in a week without charging. In his words; 

“If the car is driven 4 days a week for a maximum of 50 km a day, there’s no need to plug into an outlet”.

In spite of the criticism towards this neoteric development such as the belief by expert analysts that this technology still needs a few more years to ‘cultivate’ as it is still in its nursing stage. Evidently, there is still a lot of work to be done in order to achieve the kind of solar power needed to efficiently fuel the solar car. 

That been said Toyota, however, surpasses this hurdle through its affiliation with Sharp. Whereas the advanced solar panels provisioned by Sharp is capable of converting sunlight efficiently at a rate of over 14% more than the average solar panels available on the market nowadays.

Ecuador Data Breach: Records of Over 20 Million Users Exposed

Following the outbreak of a number of cybersecurity mishaps in recent times. Ecuador as at Monday, 16th September, experienced a major data breach baring the personal information of almost all the population of Ecuador to unlicensed third-party agents. The leaked 18Gigabyte-sized data contained research documents and statistics on over 20 million individuals.

The leaked data encompasses such information as names, addresses, employment status, phone numbers, and national identity numbers. Derived from about 7.5 million personage financial and banking records, 2.5 million car ownership logs as well as detailed information on infant demography in the region, to the tune of 6.7 million children data.

According to the report released by ZDNet, this data infringement is believed to be as a result of carelessness on the part of the administrators of the IT consulting firm who allowed entry to the Elasticsearch server unchecked and without a password. Otherwise granting access to these records to anyone on the Internet.

In a statement issued by the Ministry of Telecommunications and Information Society on Monday. The Minister of telecommunications – Andrés Michelena Ayala announced that Novaestrat – the data analytics and IT consulting firm directly involved with the leaked data, and its employees are been placed under investigation upon the charges of privacy violation and distribution of private information to the general public without due authorization.

Subsequently, the Ecuadorian authorities swooped down on Williams Roberto G. – Director of Novaestrat. As the management at Novaestrat is been slapped with the allegations of accumulating these data illegally. Although a government-endorsed data analytics firm, since Novaestrat boasts of a number of contracts been awarded by the Ecuadorian government between 2015 to 2017. What is not actually known is whether the employees at Novaestrat intentionally broadcasted this data or perhaps it was a glitch on the company’s server-side handling. 

However, one certainty stands to be that these data are originally not supposed to be in the possession of the company who might have come across such data while working extensively with the government in the past. Inclined by the gravity of the data breach, the Ecuadorian government is set to take a giant leap towards implementing a stricter data privacy law with plans to pass this new law to the parliament within the next three days.
