xMEMS' Cypress will be a massive improvement for what MEMS drivers are capable of doing for wireless earbuds.
The first affordable headphones with MEMS drivers don't disappoint
Solid-state headphones have been on the horizon for years, but the first consumer product to feature it comes from a name you might not have expected.
Creative unveils first true wireless headphones with MEMS drivers
The company partnered with xMEMS on the technology.
Could MEMS be the next big leap in headphone technology?
California-based xMEMS is one of a small handful of companies pushing the new, solid-state technology. It promises high fidelity with a tiny footprint, but will listeners be convinced?
Panasonic introduces its first true wireless, noise-cancelling earbuds
True wireless earbuds are obviously trending. At CES this year, we've already seen models by Harman Kardon, Jabra and Shure. Now, Panasonic and its Technics brand are introducing three more options: the Panasonic RZ-S500W and RZ-S300W and the Technics EAH-AZ70W.
Bosch's reworked automotive sensors can help control flying taxis
As companies from Boeing and Uber to Lilium work to develop flying taxis, Bosch wants to make the sensors they'll require more accessible. The company says conventional aerospace technology is too expensive and bulky to use in autonomous flying vehicles. So, today, Bosch announced a plug-and-play sensor box that adapts automotive industry sensors for use in flight.
'Hovering' antennas promise speedy 5G phone networks
Wireless networks already have to deal with increasingly crowded waves, and that's only going to get worse when 5G rolls around. Any boost to the signal could lead to a big jump in performance, especially when you're using very high frequencies that are more prone to interference. But how do you provide that boost? Researchers have an idea: 'hover' the antenna. They've developed millimeter wave antenna arrays that are almost entirely separated from the substrate you'd usually mount them on, preventing that substrate from weakening the signal like it does with conventional antennas.
Qualcomm's Raj Talluri: wearable displays should always be on
Qualcomm isn't exactly known for launching its own consumer products, but in the case of its $350 Toq smartwatch, the move makes sense for Raj Talluri, SVP of Product Management. "Sometimes you have to build the whole thing to show what's possible," said the exec. "Qualcomm has a history of doing that." What Talluri's referring to here is how Qualcomm's once-dormant Mirasol technology enables always-on wearable displays, while maintaining a low power consumption. This contrasts with the experience on many other LCD-powered smartwatches, which have their screens turned off while idle to save power. This pain point alone is enough to deter the average consumers.
World's smallest FM transmitter built with graphene, ruined by Psy
Researchers have been using graphene to develop an assortment of technologically advanced things for a while, from camera sensors and contact lenses all the way to frickin' lasers. That's why it's not a surprise to see a group of engineers from Columbia University create the world's smallest FM transmitter using the atom-thick material. The end product isn't just for show, either, as it can pump tunes over the airwaves to a regular FM radio -- the team even used Gangnam Style to prove that it works. As interesting as the teensy transmitter is, the engineers have no plans to build a radio for ants, and this is merely part of a larger study into nano-electromechanical systems. Now all we need is for someone to make a tiny violin and a pair of tweezers small enough for us to play.
Oppo phone, not Nexus 5, will be first to nab DigitalOptics' speedy MEMS camera
DigitalOptics has just announced that its MEMS multi-focus camera unit will arrive first on an Oppo handset, calling reports that it might first come to a rumored LG Nexus 5 "inaccurate." It added that Oppo is an "exclusive launch partner" for now, saying the modules will arrive in its premium models at some point in the future. The Lite-on-built 8-megapixel camera module has drawn buzz thanks to its high speed focusing compared to a typical voice coil-equipped smartphone camera, enabling possibilities that are somewhat similar to Lytro image capture. If you're interested in seeing whether the reality can live up to that, however, it appears you'll have to scratch Google's next handset off your list.
DigitalOptics enlists Lite-On for MEMS camera production
Five months after DigitalOptics' memscam module showed off its Lytro-like multi-focus feature at MWC, it has a production contract. Lite-On, the company known for budget Blu-ray drives and moldable mice, plans to start production of the speedy camera part later this year and hit "high volume capacity" sometime in 2014. We left MWC impressed by the MEMS' (microelectromechanical system) 10ms settling time and are curious where this clever contraption could wind up. Speaking of which, Lite-On assures us that its "Chinese Smartphone customers" are interested.
Qualcomm finishes $120 million investment in Sharp, becomes third-largest investor
Chipmaker Qualcomm has finalized its investment in beleaguered display manufacturer Sharp. Announced back in December 2012 and totaling $120 million, the second portion of the investment was delayed earlier this year when Sharp failed to satisfy conditions for the investment. Sharp's now confirmed the transaction, which gives Qualcomm a 3.53 percent share of the display maker, and will presumably increase its involvement on new screen tech being developed between the two companies. The combination of Qualcomm's MEMs display products and Sharp's high-resolution IGZO screens will apparently make its way into a number of devices in varying sizes. Qualcomm isn't the only company with a vested interest in Sharp's recovery, either -- Samsung also holds a 3 percent stake.
HTC says One's dual-membrane microphones block bad vibes
Nobody expects studio quality recording from a smartphone, but the technology in HTC's recently launched One at least allows distortion free audio to be nabbed in the quietest or loudest environments, according to the company's blog. Describing BoomSound tech, HTC says the system brings two dual-membrane MEMS microphones to the handset, one of which is focused on sensitivity and the other on high decibel sources. The two signals are then combined electronically, resulting in whisper-level tones that are free of hiss along with concert level blasting that won't clip or distort. By HTC's reckoning, that means the audio that goes along with those UltraPixels will be clear whether you're capturing a physics lecture or death metal concert.
DigitalOptics' fast MEMS camera enables Lytro-like post-capture refocus (video)
Tech shows like CES and MWC are great for taking a peek at what's coming up in the world of consumer electronics, even down to the component level. At the latter show this year, we came across DigitalOptics whose name may not sound familiar, but you may already be using its HDR, red eye removal, face tracking, face beautification and other related technologies on many phones (like Oppo's) and cameras (sorry, not allowed to name them here). Now, this year the company will also be offering its MEMS (microelectromechanical system) lens actuator which, compared to its traditional voice coil counterpart, is apparently more reliable, longer lasting, more efficient and faster with a 10ms settling time instead of the usual 20 to 25ms.
Xsens teases wearable 3D body sensors that won't cost, will track an arm and a leg (video)
When we think of full-body motion capture, we most often associate it with movie-grade equipment that demands a dedicated room, odd-looking suits and a corporate bank account to finance it all. Xsens hints that we may not have to rent a professional studio (or stand in front of a Kinect) to get complete body tracking for personal use. It's planning to show a wearable, 3D-capable tracking system at CES that uses "consumer grade" MEMS sensors to monitor joint positions and movement -- in other words, the kind of technology that might go into a phone's accelerometer, just strapped to our arms and legs. Further details are scarce, although Xsens is pressing for uses in everything from fitness to gaming. We'd like to see partners line up so that there's a product we can buy in a store. Until then, we'll have to make do with the company's skateboard-dominated teaser clip, which you can find after the break.
Qualcomm COO Steve Mollenkopf talks 28nm supply, low-end market and displays
It goes without saying that it's been a good year for Qualcomm -- so good that the mobile chipmaker invited us over to its San Diego headquarters to share the story. There we met up with President and COO Steve Mollenkopf, who started off the session by reflecting on the 28nm production "issues" since mid-year. Without naming any participating foundries, Mollenkopf carefully reiterated that the supply struggled to match the "tremendous demand" of the new 28nm Krait-based products at the time, but he thinks Qualcomm will be out of that problem starting this month. "It was something that we had this year and last fiscal year, but moving forward, I don't see that to be an issue," said Mollenkopf. Judging by the increasing number of devices carrying Qualcomm's quad-core chipsets, we certainly hope this is the case.
Sharp and Qualcomm to team up for energy-efficient IGZO display venture
We already knew that Sharp's been asking around for some much-needed help recently, and now we can all breathe a sigh of relief, as Nikkei is reporting that said manufacturer has finally found a new friend to help co-develop its energy-efficient IGZO LCD panels. Set to announce as soon as Tuesday (presumably Japan time), the deal will involve Qualcomm initially throwing in five billion yen ($61 million) by the end of the year, with a double-down of another five billion yen after "sufficient progress has been made." There's no timeline yet on when (or if) a full investment would be secured, but if all goes to plan, Qualcomm will eventually hold nearly five percent of Sharp's stock, whereas Sharp will more or less get back the 10 billion yen it lost to Sony following the termination of their joint venture earlier this year. Additionally, Sharp will also share some of the IGZO magic with Qualcomm to help improve the latter's Pixtronix MEMS display technology. Not a bad way for the two companies to wrap up 2012, eh? Richard Lai contributed to this report.
STMicroelectronics details pressure sensor in your Galaxy S III, can tell when you're mountaineering
If you're the sort to tear down your Galaxy S III, you might have noticed a mysterious STMicroelectronics LSP331AP chip lurking on the motherboard. While we've known that it's a pressure sensor, we now know that it's a new generation -- new enough that ST is just getting to explaining the technology to a mainstream audience. The piezoresistor-equipped MEMS chip tracks altitude through atmospheric pressure with an uncanny knack for precision; it can tell when you've crossing between floors, which could be more than handy for future iterations of indoor navigation. Don't worry if you're an extreme sports junkie that might push the limits, either. The sensor can do its job at the kinds of pressure you'd normally see when 32,800 feet high or 5,900 feet below sea level, which should keep it working even if you're checking your phone during a climb up K2 or a HALO skydive. We don't know if anyone beyond Samsung is lined up to use ST's pressure sensor in their devices, but we wouldn't be surprised if it becomes a mainstay for smartphones and outdoor gear in the near future.
Engineer Guy shows how a phone accelerometer works, knows what's up and sideways (video)
We love finding out how things work, and arguably one of the most important parts of the smartphones and tablets we thrive on is the accelerometer gauging our device's orientation. Imagine our delight, then, when we see the University of Illinois' Bill Hammack (i.e. The Engineer Guy) giving a visual rundown of how accelerometers work. Although it's certainly the Cliff's Notes version of what's going on in your Android phone or iPhone, the video does a great job of explaining the basic concepts behind three-axis motion sensing and goes on to illustrate how MEMS chips boil the idea down to the silicon form that's needed for our mobile hardware. Hammack contends that it's one of the coolest (and unsung) parts of a smartphone, and we'd definitely agree; you can see why in the clip after the break.
Gyroscope manufacturers benefit as iPhone, iPad sales soar
Apple isn't the only company reaping the benefits of increased sales of the iPhone and iPad. IHS iSuppli is reporting that sales of MEMS (microelectromechanical systems) gyroscopes have skyrocketed as well thanks to use of the devices in Apple's mobile line. (Photo above is of an iPhone 4 MEMS gyro -- not this kind of gyro -- component.) MEMS gyroscopes accounted for US$665.4 million in revenues in 2011, compared with only $394.5 million in 2010 -- a 66% rise in revenues in just one year. IHS iSuppli explains the popularity of MEMS gyroscopes in today's mobile electronic devices: "The rise of gyroscopes to the top was in large part due to the boom in 3-axis versions of the device, used mostly in tandem with 3-axis accelerometers for more accurate motion sensing. While accelerometers are responsible for correctly orienting phones and tablets to the viewer's perspective whether the devices are held vertically or horizontally, gyroscopes improve the motion-based interface, especially for gaming. Emerging applications for gyroscopes in smartphones also include optical image stabilization and navigation-related functions." In Apple's iPad and iPhone, the MEMS gyroscopes come from one supplier: STMicroelectronics. Half of the company's 2011 MEMS revenues came from sales to Apple. In the near future, it's expected that companies like Apple will switch to what are called 6-axis inertial measurement units, which combine the 3-axis gyros and 3-axis accelerometers onto one chip.
