Murata：Radisol Redefines Antenna Interference Countermeasures for Smartphones and Wearables

　　Murata Manufacturing Co. Ltd announces the launch of Radisol – an innovative product designed to suppress interference between nearby antennas with low insertion loss, improving isolation and antenna radiation efficiency. This world-first solution is specifically engineered to meet the demands of compact modern devices like smartphones and wearables, offering benefits such as reduced power consumption, miniaturized construction, and enhanced communication quality. In addition, Radisol has been adopted by Motorola Mobility LLC (Headquarters: Libertyville, Illinois, USA, President: Sergio Buniac), in the new Edge series of smartphones scheduled to be released in August 2024. Motorola has realized a method of improving the characteristics of Wi-Fi® antennas by using Radisol.　　As the demand for smaller smartphones and wearable devices grows, the number of antennas is also increasing to accommodate the expanding range of communication methods and bands. Additionally, MIMO technology to improve communication quality and speed is encouraging an increase in the number of antennas, while new designs such as foldable smartphones are encouraging antenna crowding. This has posed new difficulties, specifically the implications on antenna isolation and the decline in antenna effectiveness, as the interference of nearby antennas leads to a decrease in radiation efficiency.　　Although discrete filters are a common solution for improving antenna isolation, they are not suitable when communication bands are closely situated, as insertion loss can impair antenna performance and occupy valuable board space. To address these challenges, Murata has created Radisol, a low-loss filter for antenna area that uses Murata’s unique ceramic multilayer technology and RF circuit design technology.　　Antenna engineers usually construct a filter circuit using discrete L and C chip components to implement effective countermeasures. Instead, Radisol is just a single 0603-sized component that resolves the persisting challenges of antenna performance and packaging constraints. It effectively suppresses antenna interference, without significantly impacting the passband, and results in enhanced radiation efficiency and reduced power consumption.　　Each Radisol component operates as a dedicated filter circuit designed specifically to mitigate the antenna interference associated with a specific communication band. The compact component integrates one capacitor and two inductors, providing band-stop filter characteristics within a single chip. Radisol features a unique design that utilizes the generation of lossless mutual inductance by two magnetically coupled coils. This setup forms a band-stop circuit with no notable insertion loss in the communication band. This specialized approach to antenna isolation enables Radisol to offer enhanced performance, with low insertion loss and high efficiency and system integration.　　Included in the Radisol family are variants designed to effectively address the needs of common bands, including 2G & 5G Wi-Fi® as well as GPS signals. This eliminates the necessity of designing discrete filter circuits, simplifying the implementation of countermeasures. Murata will continue to expand upon the initial product lineup to further meet market demands and drive further innovation in antenna technology.　　“By using Radisol engineers can address the challenges of modern communication devices without compromising signal integrity and radiation efficiency,” said Satoru Muto, General Manager of New Business Incubation Department at Murata. “By utilizing Murata's cutting-edge technology, this solution takes integration to a whole new level, eliminating the need for complex discrete filter circuits and saving valuable space.”　　Radisol samples are available for evaluation and mass production has already begun in June 2024.

Wearables Market Hits Speed Bump

Growth in wearable electronic device shipments is expected to slip below 10% for the first time in 2018 before returning to double-digit percentages each year from 2019 to 2022, according to market research firm IDC.IDC (Framingham, Mass.) forecasts that shipments of wearables — including smart watches, wristbands, earwear and other devices — grow to 122.6 million units this year, up 6.2% from 115.4 million units last year. IDC blamed the lower growth on continued softness in sales of basic wearables — devices that do not run third-party applications."The slowdown in the worldwide wearables market is a sign that this is a market in transition instead of a market in slowdown," said Ramon T. Llamas, research director for IDC's Wearables team, in a press statement.Llamas said vendors are moving beyond first-generation devices, bringing together ecosystems of partners and applications. "The wearables of tomorrow will play a more prominent role in communication, digital health care, home IoT and enterprise productivity that will make last year's wearables look quaint," Llamas predicted.Apple Chief Operating Officer Jeff Williams introduces the Apple Watch 4 at the company's event last week.Source: AppleIDC forecasts that wearable device shipments will increase at a compound annual growth rate (CAGR) of 10.6% between 2018 and 2022, reaching 190.4 million units."The shift from basic wearables to smartwatches is well on its way," said Jitesh Ubrani senior research analyst for IDC Mobile Device Trackers. "With it, we anticipate far greater diversity in terms of design, feature set, brands, and most importantly, price points than ever before. Ubrani said IDC expects growth to come from sub-$200 smartwatches as well as new products as kid's brands, fashion brands and sports brands."Although kids’ wearables have been a phenomenon in the Asia/Pacific region, they are just beginning to emerge in Europe and Latin America with the North American market to follow," Urabni said. "Meanwhile, the third generation of WearOS watches are expected to make a small splash this holiday season and gain traction throughout 2019." IDC forecasts that the shipments of smartwatches will reach 46.2 million this year, up 39% compared to 2017. The firm expects smartwatch shipments to grow at a 19.5% CAGR, reaching 94.3 million in 2022 and accounting for nearly half the wearables market.Shipments of smart wristbands are expected to remain roughly flat from 2018 through 2022, but IDC expects the devices to continue to play a significant role in the wearables market. Shipments of earwear — electronic devices that feature functionaility beyond simple audio such as fitness tracker/coaching devices and real-time language translation — are expected to grow fastest of all wearables categories over the five-year forecast period, IDC said.

IDC Forecasts Slower Growth for Wearables in 2018 Before Ramping Up Again Through 2022

The worldwide wearables market is forecast to ship 122.6 million units in 2018, up 6.2% from the 115.4 million units shipped in 2017, according to the International Data Corporation (IDC) Worldwide Quarterly Wearable Device Tracker. This will be the first year of single digit year-over-year growth for the wearables market, mostly due to continuing softness among basic wearables (devices that do not run third-party applications). However, double-digit growth will return in 2019 and through the rest of the forecast as smartwatches and new form factors gain acceptance. In 2022, IDC expects total shipment volumes will reach 190.4 million units, resulting in a compound annual growth rate (CAGR) of 11.6% over the five-year forecast."The slowdown in the worldwide wearables market is a sign that this is a market in transition instead of a market in slowdown," said Ramon T. Llamas, research director for IDC's Wearables team. "Vendors are slowly moving beyond first-generation devices and experiences, bringing together an ecosystem of partners and applications for improved user experiences that reach beyond step counting. The wearables of tomorrow will play a more prominent role in communication, digital health care, home IoT, and enterprise productivity that will make last year's wearables look quaint.""The shift from basic wearables to smartwatches is well on its way," said Jitesh Ubrani senior research analyst for IDC Mobile Device Trackers. "With it, we anticipate far greater diversity in terms of design, feature set, brands, and most importantly, price points than ever before. Fitbit's Versa was one of the first mass market smartwatches to target the sub-$200 price band and in the next six to twelve months consumers can expect more options in the same or lower price tiers."Apart from smartwatches, we also expect growth from new products as kid's brands, fashion brands, and sports brands begin to to hit the shelves," added Ubrani. "Although kids’ wearables have been a phenomenon in the Asia/Pacific region, they are just beginning to emerge in Europe and Latin America with the North American market to follow. Meanwhile, the third generation of WearOS watches are expected to make a small splash this holiday season and gain traction throughout 2019.""Through all these changes there will still be an appetite for basic wearables," noted Llamas. "Wristbands will continue to play a significant role in the wearables market, offering simpler and less expensive solutions than their smartwatch counterparts. We also expect these devices will bring a more smartwatch-like experience to the table. Meanwhile, clothing and earwear will post market-beating growth with use cases that go well beyond their primary functions."Forecast HighlightsSmartwatch volumes will reach a total of 46.2 million units shipped in 2018, up 38.9% from the 33.3 million units shipped last year. By 2022, total volumes will grow at a CAGR of 19.5% and reach 94.3 million units shipped, accounting for nearly half the entire wearables market. In the near-term, expect a boost from Fitbit's entry in the market as well as a reinvigorated WearOS to spur volumes. At the same time, Apple's new Watch will appeal to cardiac patients thanks to its approval from the FDA and AHA, and its refreshed watchOS5 provides reason for owners of older versions to upgrade.Wristband volumes will remain essentially flat throughout our forecast. Although numerous vendors have exited in recent quarters and more will exit in the years to come, what will remain are best-of-breed devices that go beyond step counting and move towards being a health and fitness companion. Combined with their simple value proposition and lower prices compared to smartwatches ($44 USD vs $289, respectively) wristbands will continue to play a significant role in the wearables market.Earwear will grow the fastest among all the other wearables products on our list. In this category, we included those devices that feature a plus-one functionality beyond audio, and already earwear has expanded to include fitness tracking and coaching and real-time language translation, and in the coming years it should not be difficult to imagine a smart assistant tucked into a user’s ear.

Paper based supercapacitor could power wearables

　　Using a simple layer-by-layer coating technique, researchers from Georgia Tech and Korea University have developed a paper-based flexible supercapacitor that could be used to help power wearable devices. The device uses metallic nanoparticles to coat cellulose fibres in the paper, creating supercapacitor electrodes with high energy and power densities – and the best performance so far in a textile-based supercapacitor.　　“This type of flexible energy storage device could provide unique opportunities for connectivity among wearable and internet of things devices,” said Seung Woo Lee, an assistant professor at Georgia Tech. “We also have an opportunity to combine this supercapacitor with energy-harvesting devices that could power biomedical sensors, consumer and military electronics and similar applications.”　　The process uses an amine surfactant to bind gold nanoparticles to the paper. Using a repeating process, the researchers created a conductive paper on which alternating layers of metal oxide energy storage materials were added.　　“It’s basically a very simple process,” Lee said. “We can fold the resulting metallised paper and otherwise flex it without damage to the conductivity.”　　The self-assembly technique is said to improve several aspects of paper supercapacitors, including areal performance. The maximum power and energy density of the metallic paper-based supercapacitor is estimated to be 15.1mW/cm 2 and 267.3μWh/cm2 – said to be better than conventional paper or textile supercapacitors.　　The next steps will include testing the technique on flexible fabrics and developing flexible batteries that could work with the supercapacitors. “We have nanoscale control over the coating applied to the paper,” Lee added. “If we increase the number of layers, the performance continues to increase. And it’s all based on ordinary paper.”

Wearables Shipments Swell as Consumer Tastes Shift

　　Worldwide shipments of wearable devices surged by nearly 18 percent in the first quarter as both the high-end Apple Watch and a slew of low-cost devices gained traction among consumers, according to market research firm International Data Corp. (IDC).　　Apple Inc. and Xiaomi Inc. have surpassed Fitbit Inc.—the early leader in wearables shipments—and now control nearly 15 percent of the market apiece, IDC (Framingham, Mass.).　　Ramon Llamas, research man ager for IDC's Wearables team, said through a press statement that consumer tastes in wearables have evolved from fitness bands to smartwatches and other products, fueling growth for the product category.　　"This allowed Xiaomi to throttle up on its inexpensive devices within the China market and for Apple to leverage its position as the leading smartwatch provider worldwide," Llamas said. "Now that Xiaomi and Apple have supplanted Fitbit, the next question is whether they will be able to maintain their position."　　Companies shipped 24.7 million wearable devices in the first quarter, up from 20.9 million in the first quarter of last year, according to IDC's wearables market tracker.　　Llamas said Fitbit remains a key player in the wearables market despite being outpaced by Apple and Xiaomi in recent quarters.　　"With a user base of 50 million, a strong presence within corporate wellness, and assets that keep it top of mind for digital health, Fitbit is well positioned to move into new segments and markets," Llamas said.　　Jitesh Ubrani, a senior research analyst for IDC, said the wearables market is still arguably in its first phase of development, where companies are seeding the market and trying to get consumers accustomed to wearing a device.　　Earlier this year, Llamas said the wearables market is shifting and would enjoy a very strong 2017 thanks to the addition of cellular connectivity in wearable devices and a slew of new products on the market, including fashionable watches that resemble more classic wristwatches as opposed to high-tech devices.　　Ubrani said the current market wearables opportunity makes it very enticing for traditional and fashion watch brands,　　Ubrani said the second phase of development of the wearables market would be all about putting the user data accumulated by wearables to good use.
