Integrated Electronics Trends to Drive IME Market to $1.5bn by 2032

Sep 21, 2021

In-mold electronics enables electronic functionality to be embedded within molded and thermoformed plastic components. With the integration of capacitive touch, lighting, and even haptics alongside size and weight reductions of up to 70%, IME is an efficient approach to making curved touch-sensitive interfaces. Given these benefits, IDTechEx forecasts IME to be a $1.5 billion market by 2032, with applications mainly within the automotive and consumer goods sectors.

Greater integration of electronics within 3D structures is an ever-increasing trend, representing a more sophisticated solution compared to the current approach of encasing rigid printed circuit boards. In-mold electronics (IME) facilitates this trend, by enabling multiple integrated functionalities to be incorporated into components with thermoformed 3D surfaces.

New optical 'transistor' speeds up computation up to 1,000 times, at lowest switching energy possible

by Skolkovo Institute of Science and Technology
https://phys.org/news/2021-09-optical-t ... nergy.html
An international research team led by Skoltech and IBM has created an extremely energy-efficient optical switch that could replace electronic transistors in a new generation of computers manipulating photons rather than electrons. In addition to direct power saving, the switch requires no cooling and is really fast: At 1 trillion operations per second, it is between 100 and 1,000 times faster than today's top-notch commercial transistors. The study comes out Wednesday in Nature.

"What makes the new device so energy-efficient is that it only takes a few photons to switch," the first author of the study, Dr. Anton Zasedatelev commented. "In fact, in our Skoltech labs we achieved switching with just one photon at room temperature. That said, there is a long way to go before such proof-of-principle demonstration is utilized in an all-optical co-processor," added Professor Pavlos Lagoudakis, who heads the Hybrid Photonics Labs at Skoltech.

Since a photon is the smallest particle of light that exists in nature, there is really not much room for improvement beyond that as far as power consumption goes. Most modern electrical transistors take tens of times more energy to switch, and the ones that use single electrons to achieve comparable efficiencies are way slower.

Besides performance issues the competing power-saving electronic transistors also tend to require bulky cooling equipment, which in turn consumes power and factors into the operating costs. The new switch conveniently works at room temperature and therefore circumvents all these problems.

Researchers say 'unusual' metamaterial could double capacity of wireless networks
https://techxplore.com/news/2021-09-unu ... works.html
by Matthew Tierney, University of Toronto

Your office wall may play a part in the next generation of wireless communications.

University of Toronto researchers George Eleftheriades and Sajjad Taravati have shown that reflectors made of metamaterials can channel light to enable more wireless data to be transmitted over a single frequency.

They believe this newly realized property—called "full-duplex nonreciprocity"—could double the capacity of existing wireless networks. Their research is published in a paper in Nature Communications.

"This is happening," says Eleftheriades, a professor in the Edward S. Rogers Sr. department of electrical and computer engineering in the Faculty of Applied Science & Engineering.

"Within the next three to five years this technology will be adopted."

The intellectual property for the team's proof of concept was recently transferred to the Montreal-based startup LATYS Intelligence Inc., which was co-founded by U of T Engineering alumnus Gursimran Singh Sethi.

Metamaterials are synthetic structures composed of building blocks that are smaller than the wavelengths of light they are designed to manipulate.

The material used by the team is composed of repeating unit cells about 20 millimeters in size. They appear to form one homogenous object—a metasurface—for larger wavelengths of light such as microwaves, which are used to carry cell phone signals and reflect off the metasurface exhibiting a property known as nonreciprocity.

Eleftheriades uses a car's rear-view mirror to illustrate how it works.

"When you're driving and look in the rear-view mirror, you see the driver behind you. That driver can also see you because light bounces off the mirror and follows the same path backwards," he says.

Record Data Speed – 319 Terabits per Second Over 3,001 km
September 27, 2021 by Brian Wang
Researchers constructed a transmission system that makes full use of wavelength division multiplexing technology by combining different amplifier technologies, to achieve a transmission demonstration with date-rate of 319 terabits per second, over a distance of 3,001 km. Using a common comparison metric of optical fiber transmission the data-rate and distance produce of 957 petabits per second x km, is a world record for optical fibers with standard outer diameter. Researchers at Japan’s National Institute of Information and Communications Technology developed an experimental optical fiber with four cores, instead of just one.

In addition to the C and L-bands, typically used for high-data-rate, long-haul transmission, we utilize the transmission bandwidth of the S-band, which has not yet been used for further than single span transmission. The combined >120nm transmission bandwidth allowed 552 wavelength-division multiplexed channels by adopting 2 kinds of doped-fiber amplifier together with distributed Raman amplification, to enable recirculating transmission of the wideband signal. The standard cladding diameter, 4-core optical fiber can be cabled with existing equipment, and it is hoped that such fibers can enable practical high data-rate transmission in the near-term, contributing to the realization of the backbone communications system, necessary for the spread of new communication services Beyond 5G.

This could be used to upgrade the global interent backbone.

Using optical beaming to power a portable 5G base station

by Bob Yirka , Tech Xplore
https://techxplore.com/news/2021-10-opt ... -base.html
Telecommunications company Ericsson has teamed up with a company called PowerLight Technologies to send power through the air to run a 5G base station. Both companies have posted the details on their respective websites.

Consumers have already seen through-the-air power exchange in the form of wireless charging stations—such stations have used a form of technology to transfer electricity short distances, a type of energy transfer that is not expected to work over long distances. In this new effort, the two companies took a different approach—they developed a system called optical beaming in which a sending station converts electricity to a powerful beam of light that is sent through the air to a receiving station.

The light is captured at the receiving station using a special type of photovoltaic array and is then converted to electricity. The two companies have proven their concept viable by sending power from a sending station to an Ericsson 5G radio base station, which, they note, did not have any other source of power. The test system sent 48 watts over 300 meters. In its announcement, Ericsson claims that the system is capable of sending up to 1,000 watts up to distances of a kilometer. Noting that the power in the beam of light could present a hazard to both humans and wildlife, the team built a ring of protection around it—sensors formed in a ring around the beam that detect the presence of anything coming between the sending and receiving stations. In such circumstances, the beam is cut off and the base station operates temporarily on battery power.

Enhanced touch screens could enable users to 'feel' objects
https://techxplore.com/news/2021-10-scr ... users.html
by Steve Kuhlmann, Texas A&M University College of Engineering
The next time you buy a new couch, you may not ever have to leave your old one to get a feel for the texture of the new material.

Dr. Cynthia Hipwell, Oscar S. Wyatt Jr. '45 Chair II Professor in the J. Mike Walker '66 Department of Mechanical Engineering at Texas A&M University, is leading a team working to better define how the finger interacts with a device with the hope of aiding in the further development of technology that goes beyond sensing and reacting to your touch.

The team's research was recently published and featured on the cover of the journal Advanced Materials.

The ultimate goal of furthering this human-machine interface is to give touch devices the ability to provide users with a richer touch-based experience by equipping the technology with the ability to mimic the feeling of physical objects. Hipwell shared examples of potential implementations ranging from a more immersive virtual reality platform to tactile display interfaces like those in a motor vehicle dashboard and a virtual shopping experience that would let the user feel the texture of materials before purchasing them.

"This could allow you to actually feel textures, buttons, slides and knobs on the screen," Hipwell said. "It can be used for interactive touchscreen-based displays, but one holy grail would certainly be being able to bring touch into shopping so that you could feel the texture of fabrics and other products while you're shopping online."

Hipwell explained that at its essence, the "touch" in current touch screen technology is more for the screen's benefit than the user. With the emergence and refinement of increasingly sophisticated haptic technology, that relationship between user and device can grow to be more reciprocal.

Quantum-encrypted information transmitted over fiber more than 600 kilometers long

by The Optical Society
https://phys.org/news/2021-10-quantum-e ... eters.html
By implementing a new signal stabilization technique, researchers were able to achieve secure quantum communication over a record 605 kilometers of fiber using the twin-field quantum key distribution (QKD) protocol. The new demonstration paves the way for transmitting highly secure, quantum-encrypted information over long distances, such as between cities.

Mirko Pittaluga from Toshiba Europe Limited and the University of Leeds, both in the UK, will present the research at the Frontiers in Optics + Laser Science Conference (FiO LS) all-virtual meeting.

"This research extends the range of fiber-based quantum communications beyond 600km for the first time, and we think the techniques we have introduced here may be relevant for other phase-sensitive single-photon applications," said Mirko Pittaluga. "This will allow us to build national and continental scale fiber networks connecting major metropolitan areas. Together with satellite links, we can now envisage truly global quantum networks," continued Andrew Shields, head of the quantum technology division at Toshiba Europe.
