It’s a thin band with a physical button on the side.Both have touchscreens, although the Charge 3 has a monochrome display compared to the Versa’s color LCD. You can swipe across from the sides of the display to access fitness tracking features or settings. To go back, press the side of the Charge 3. The Versa has three physical buttons that let you go back, start or stop activities, and make selections.You can change the watch faces on both in the Fitbit app. But the Charge 3 has fewer watch faces to choose from than the Versa, which has plenty of third-party options.Change the straps with this toggle on the Versa (left) and button on the Charge 3 (right). Angela Lang/CNET I found it hard to see the display on the Charge 3 in direct sunlight, regardless of the brightness setting selected (you can choose between auto or normal brightness). For me, the Versa was easier to see outdoors and you get an extra brightness setting to choose from.To change up the look of your Fitbit, each offers interchangeable straps. The Charge 3 has quick release buttons at the back, while the Versa uses a small metal bar that you have to toggle to change the strap. It’s a lot easier to swap the straps out on the Charge 3 than it is the Versa, especially if you’re looking for a quick change.Each display is coated in Gorilla Glass 3 to protect against scratches and bumps.Winner: Tie, depending on which size you preferFitness tracking features are similar on bothBoth Fitbits have an optical heart rate sensor, sleep tracking, female health tracking and water resistance to 50 meters. Neither has GPS built-in. Instead, they use connected GPS. So if you want to track your route, pace and elevation during an outdoor workout, you’ll need to take your phone with you.Check out your previous workouts from the Fitbit app. You can also tap into each one to see a breakdown of heart rate zones and calories. Tracking a run will also show a breakdown of your average pace. Screenshot by Lexy Savvides/CNET They both have automatic workout detection, and you can set goal-based exercises to get a notification once you pass a set distance, time or calorie goal.The Charge 3 lets you put six different workout shortcuts on the exercise screen, while the Versa gives you space for seven shortcuts. You can choose from 19 workout types from the Fitbit app (run, hike, walk, swim, bike, spinning, pilates, interval workout, golf, elliptical, weights, workout, treadmill, stairclimber, yoga, tennis, kickboxing, circuit training, martial arts, bootcamp). Both give you reminders to move, prompting you to complete a number of steps an hour to “win”.I found the fabric and plastic Fitbit straps fairly comfortable to work out with during a run or sweaty Pilates session.Thanks to its larger screen, the Versa gives you more metrics from your workout once you complete your exercise routine. It’s also the only one that lets you go back and view your past few workouts from the watch face, rather than diving into the Fitbit app itself.The Versa has lots of third-party apps available (which we’ll cover in the next section) which makes it easier if you prefer to track your workout in a different app. During workouts, I found the Charge 3 often gave a higher reading on my heart rate than the Versa. During an outdoor run, it said my maximum heart rate was over 200 beats per minute. From using previous heart rate trackers and smartwatches (and comparing with the Versa), running at the same intensity on the same route never gave me a max heart rate over 190.The Versa comes with the Coach app. A bit like a personal trainer on your wrist, it runs you through a sequence of moves with quick visual cues on the screen. It’s a nice extra if you want to squeeze in a quick workout. For similar workouts on the Charge 3, you’ll need to use the Fitbit Coach app on your phone.Fitbit metrics don’t sync to Apple Health, so keep this in mind if you are an iOS user who likes to consolidate data in one app.Winner: VersaBoth have smartwatch features, but the Versa does moreIt’s easy to get notifications mirrored from your phone on each Fitbit, and they both work with iOS and Android. That being said, you’ll only be able to respond to notifications if it’s tied to Android. You can customize quick responses to messages from the Fitbit app.Fitbit Pay is a mobile wallet that lets you tap to pay with NFC at compatible terminals. It’s only available if you buy the special edition of both (which does come at a premium). Angela Lang/CNET The Versa is the only one that can store music. It has space for around 300 songs, but the process to get those tunes onto the watch is cumbersome. You need to download a desktop app then make sure the Versa and your computer are on the same Wi-Fi network to start the transfer.If you prefer a streaming service, the only two options available are Pandora and Deezer, as long as you have a subscription. There is a third-party Spotify app available, but it is only to control playback from your phone.There are also many more third-party apps available on the Versa than there were when it first launched. Here’s a list of some of our favorites. The Charge 3 doesn’t have third-party apps at the time of writing.As the Versa was released in April 2018, a new edition of the watch potentially called Fitbit Versa 2 may be around the corner. We don’t have any insider information, but we’d love to see on-board GPS and Fitbit Pay integrated into the new version.Winner: VersaBattery life is stellar on the Charge 3There’s no contest here. You’ll get around six to seven full days on the Charge 3 before you need to juice it up, while the Versa gives you around four full days. Each has a proprietary clip-in charger. If you’re coming from the Charge 2, the cable for the Charge 3 is different.Winner: Charge 3What about price?At the time of writing, the Charge 3 costs $150 for the regular edition and $20 more gets you the special edition with Fitbit Pay and extra bands. The Versa is $200 and the special edition, also with Fitbit Pay, costs $30 more. Since the Versa was released almost a year ago, it has been discounted several times to a price that’s pretty comparable to the Charge 3 (the cheapest we’ve seen it in the past is $90).So comparing the Charge 3 and the Versa on price isn’t always straightforward, as you can get them for around the same price at certain times of the year.Winner: TieWhich is the best Fitbit for me?If you want Fitbit’s top of the line fitness tracker with a heart rate monitor and without too many bells and whistles, get the Charge 3. The battery will last you a long time and you’ll get notifications mirrored from your phone.If you’re looking for a smartwatch with a big screen, more robust fitness tracking on the watch itself, and the added bonus of a personal trainer on your wrist, get the Versa.

Digitally programmable perovskite nanowire-block copolymer composites Citation: Ultra-Fast Quantum-Dot Information Storage (2008, March 21) retrieved 18 August 2019 from https://phys.org/news/2008-03-ultra-fast-quantum-dot-storage.html Explore further This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. The information-storage market is dominated by two main types: Flash memory, used in memory sticks and cell phones, and dynamic random access memory (DRAM), which is the main memory in a personal computer. Both types have their advantages and disadvantages, but a new type of memory, based on tiny atom clusters, called quantum dots, may soon displace both of them. In research published in the March 4, 2008, online edition of Applied Physics Letters, scientists from the Technical University of Berlin, in Germany, and Istanbul University, in Turkey, describe how they created a type of quantum-dot-based memory device that can save information at speeds of only a few nanoseconds (billionths of a second).The paper’s lead author, Technical University of Berlin scientist Martin Geller, explained to PhysOrg.com, “Flash memory, which is today’s market-driver in the semiconductor industry, and which everybody knows from memory sticks, digital cameras, and mp3-players, has a slow write time. The semiconductor industry is seeking faster Flash memories, but hasn’t found an ultimate solution yet. Our quantum-dot-based memory may provide long storage time without power consumption of Flash memory, as wells as a fast write time and better scalability to real-life devices.”To be fair, the other established predecessor of quantum-dot memory, DRAM, does have some excellent qualities. It offers very fast information-access times—under 20 nanoseconds—and the information can be repeatedly written and rewritten on a DRAM; it has excellent so-called endurance. But a DRAM device has a big disadvantage: It is volatile, meaning the information has to be refreshed every ten milliseconds to be maintained, also resulting in a high power consumption.“The very first prototype of our new quantum-dot-based memory scheme is already almost as fast as DRAM,” said Andreas Marent, a physicist at the Technical University of Berlin who took part in the research. “And in contrast to DRAM or Flash, the physical characteristics of quantum dots limit the write time to the picosecond, or trillionth of a second, range. That means a better device prototype should be more than 100 times faster than today’s DRAM.”The prototype consists of quantum dots of indium arsenide (InAs), a compound of the metals indium and arsenic, embedded in a layer of gallium arsenide (GaAs; gallium is also a metal). The GaAs layer is “p-doped,” which means it contains impurity atoms that impart it with excess free positively charge called holes. This InAs/GaAs structure is topped with a layer of “n-doped” GaAs, which contains extra electrons. Altogether, the structure is a p-n diode, an electrical device that allows current to flow only in one direction.When a voltage is applied across this structure, the quantum dots become charged, which allows them to store bits of information, i.e. “0” or “1” values. Whether the quantum dots represent a 0 or 1 depends on the capacitance of the diode—how much charge it is holding. A larger capacitance indicates the quantum dots do not hold much positive charge, which equates to a “0.” A smaller capacitance means that the dots are filled with holes, representing a “1.”Geller, Marent, and their colleagues say that the write times of their quantum-dot schemes are currently limited by the experimental setup and certain physical characteristics of the memory structure. In the future, after they make improvements to the structure, they expect that write times faster than 1 nanosecond may be possible. Even picoseconds seem possible, since the structure’s physical limitation is in that range.Said Prof. Dieter Bimberg, who is the group’s leader at the Technical University of Berlin and co-author on the paper, “Our results and patents demonstrate that quantum dots like these we are studying might, in just a few years, revolutionize semiconductor memory.”Citation: Appl.
