6 Upcoming Wearable Devices Compared: What’s Hot And What’s Not

Could wearable technology lead to a merging of flesh with silicon? Futurist Ray Kurzweil predicts a “technological singularity” in which artificial intelligence surpasses the capabilities of old-school organic brains. Then as perhaps an upgrade, our silicon begins merging with our bodies. Wearables, in a primitive sense, could represent a baby step toward the singularity. But as I stood outside the gates of CES 2014, holding a limp, shoddily fashioned smartwatch, I felt skeptical. Could smartwatch technology improve my, or anyone’s, life?

Two styles of watch dominated the floor show: Notifications watches (like the Pebble, which we reviewed) and health and fitness-oriented devices. Notifications watches really don’t seem useful as we already get notifications on our phones. Health-related wearables tell you things you already should know. After all, doctors have been telling patients for generations that limiting caloric intake combined with regular cardiovascular exercise greatly improves longevity. Would receiving biometric data somehow beat the advice from medical professionals? Wearables feel like a product of yet another overhyped consumer electronics show.

Swallowing my skepticism, I plodded the sprawling Las Vegas convention center, speaking to dozens of representatives. After receiving first-hand demonstrations and interviews, I present six of the more interesting and useful wearable tech devices either on the market, or soon to enter it.

What Is Wearable Technology and What Does It Do?

Wearables first arose in the 1980s – back when calculator watches were all the rage. However, the modern incarnation didn’t show until CES 2013 – compared to its ancestors, modern wearables both collect and process data. The ground-shaking distinction between older wearables and the latest incarnations is the ability to collect biometric data.

Wearable technology provides two primary functions: First, it bi-directionally transfers information from the wearable and your smartphone or tablet. Second, wearable technology converts unused real estate on the human body into something useful. Fused into a single device, smartwatches, smart headbands, and more, allow biometric data to instantaneously sync between the user and the Internet. So far two kinds of devices (notification gadgets and health-oriented products) process two kinds of data: Biological data and smartphone notifications. The fastest growing field, however, remains health-oriented products – and if CES provides a vision of things to come, the space occupied by our physical bodies will merge with the realm of the technological.

The Devices

I received a first-hand look at a variety of wearable technologies. Compared to what we saw at CES 2013, I saw modest improvements in energy consumption and performance. Most of the new smartwatches and similar devices use custom designed circuits (known as ASIC) using ARM chips. Together, these allow for extremely low energy consumption and minuscule size. They also added Bluetooth 4.0, which allows for longer battery life for both your wearable and your smartphone or tablet.

Muse Headband: The Brain Sensing Headband

muse one headband

  • Category: Health oriented
  • Price: $299 for preorders
  • Release date: Q1 of 2013 (the revision is coming out in Q2 of 2014)
  • Sensory apparatus: EEG sensors, accelerometer
  • Wireless: Bluetooth 4.0
  • Vibration: No
  • Battery life: 4 hours
  • Water resistant: No
  • Operating system compatibility: Android, iOS
  • Other: Audio output

Unlike the other wearable tech, InteraXon’s Muse is a circlet, worn about the head. It employs seven sensors (the prototype used four), which monitor users’ brain activity, specifically EEG (electroencephalography). EEG readings are the electrical activity that shows up along the scalp (and isn’t technically direct brain activity). I received assurances by co-founder, and product manager, Trevor Coleman, that Muse can distinguish between background electromagnetic radiation and the electrical activity produced by the human body. The science of EEG readings are extremely well documented, so, for the skeptics, we know that the underlying technology is based on science.

You may recall from a myriad number of soap operas that EEG sensors read whether a comatose patient is either brain dead or simply unconscious.

It’s hilarious, and not at all an accurate representation of how EEG readings work. Here’s how last year’s Muse functions:

It’s difficult to explain exactly what Muse does, although a good summary would be that it has two primary functions: First, the device gauges general levels of mental/neurological activity the user feels, by measuring the electrical activity of the scalp. Second, it allows the user to train themselves to respond more effectively to stress and anxiety. Watching the process in action reminded me a great deal of Integrative Body-Mind Training, which to date is the best understood meditation technique ever developed. Muse takes this concept to the next level by directly providing its user with quantitative data as to whether meditation/relaxation methods actually provide any real reduction in anxiety. This information displays on any connected smartphone or tablet. It measures the following brain waves:

  • Delta waves (sleep)
  • Theta waves (sleep, deep relaxation and visualization)
  • Alpha waves (relaxation and calm)
  • Beta waves (problem solving)
  • Gamma waves (higher mental activity)

My impression of the Muse is quite high. While the concept sounds vaguely wonky, it possesses a degree of theoretical backing: A recent study done on mindfulness meditation, specifically the Integrative Body-Mind Training technique, can actually cause physical changes in brain matter. The theory behind it is quite simple: If you train yourself to respond calmly to anxiety inducing scenarios you can retain higher level cognitive functions. Taking an exam or showing up for an interview, with such training, might not cause such stress. So in theory the Muse may actually work.

Rating: Hot! The emergent field of neuro-feedback falls on the cutting edge of device development. No one else is developing anything remotely close to the Muse headband.

Fitbit Force: The Smartwatch

fitbit force

The Fitbit Force offers an incremental upgrade over the previous Fitbit Flex. It includes 7-10 days of battery life, Bluetooth Low Energy (Bluetooth 4.0) and membership at Fitbit.com, which allows its user to check logs of their daily activities. These include food and water intake, body mass and other metrics that fitness geeks would want to know. From what I could tell, the device looked well-constructed and offered the vanilla wearable tech experience: Biometrics, notifications and time. Despite its limited sensor suite, the Force offers excellent value, combining a lower price-point with smartphone syncing and some degree of biometric data on its user.

  • Category: Health oriented and smartphone notifications
  • Price: $129.95
  • Release date: Currently being recalled (see below for details)
  • Sensory apparatus: Accelerometer (3-axis) and altimeter.
  • Wireless: Bluetooth 4.0
  • Vibration: Yes (cylindrical vibration motor)
  • Battery life: 7-10 days
  • Water resistant: Yes (one meter)
  • Operating system compatibilty: Browser, Android, iOS
  • Other: OLED display

The Force’s predecessor, the Fitbit Flex (which we compared against the Jawbone), was one of the most popular health-oriented wearables of last year. It received fairly good reviews and its successor seems to receive about the same attention – that is, unless you have a skin allergy to nickel, in which case you may need to look elsewhere (update: The Force was just recalled after a rash of complaints).

Rating: Hot. The Fitbit Force remains at the top of the ruggedized wearable tech. You can take it virtually anywhere. On the downside, it doesn’t offer the sophistication of other devices and its functionality remains identical to several other wearables.

The Basis Health Tracker: Carbon Steel Edition

basis smart tracker

The Basis Carbon Steel edition Health Tracker impressed me the most, at CES. It didn’t have the longest battery endurance, or latest specifications. Nor did it come with the lowest price. Instead, it offered the widest sensor suite, and an open development API for Android and iOS (although I couldn’t find any available apps). To my knowledge, the Basis Health Tracker provides the deepest biometric information on its users out of all the smartwatches and wearable tech on the market — it falls somewhere between a medical device and a consumer product. However, Basis makes it clear that it is not a medical device and shouldn’t be used as such (likely for legal reasons).

Hilariously, the Director of Product demoing the Basis Tracker, Tejash Unadkat, held an impressive 58 beats per minute heart rate, while giving a live demo. Given the anxiety of social interaction combined with the having a video camera trained on him, Tejash’s heart rate is quite impressive. In the past, my heart rate hovered around 90  – in social situations it elevated substantially more (Tejash suggested I needed to work out more). But overall, it’s an impressive technology.

  • Category: Health oriented
  • Price: $199 via Amazon
  • Release date: Available
  • Sensory apparatus: Seven sensor suite, covering activity, sleep quality, caloric burn and more.
  • Wireless: Bluetooth 2.1
  • Vibration: No
  • Battery life: 3-4 days
  • Water resistant: No
  • Operating system compatibility: Browser, Android, iOS
  • Other: Open API for app development

My battery cut out as I was filming, but as you can see, the Basis possesses a great deal of potential. It already offers the most comprehensive sensor suite out of all the smartwatches and it stands to add additional features through its open development API (according to Tejash). The entire watch also slides in and out of a USB charging cradle and many of its components are modularized for ease of replacement. Its service also includes gamification of fitness activities. We’ve written before about how gamification’s point-based approach can improve your life.

Overall, the Basis Health Tracker Titanium Edition offers outstanding health metrics at the expense of battery life. The three or four-day battery life falls a great deal shorter than the two-years offered by Casio.

Rating: Hot! While the Basis Health Tracker falls short of perfect, its sophisticated sensor suite can provide unique insights into its user’s daily activities.

Casio Smartwatch STB-1000: Ultra Rugged Design

6 Upcoming Wearable Devices Compared: What's Hot and What's Not stb1000

The Casio STB-1000 smartwatch offers a remarkable 2-year battery life. This places it at the top of the devices in recharge cycles – it also offers vibration alerts, smartphone pairing, ruggedization and bidirectional control between a paired smartphone and the watch. Essentially, you can use the watch to operate your smartphone and vice-versa.

  • Category: Smartphone notifications
  • Price: $269 until launch; after launch it costs $299
  • Release date: Q1 of 2014
  • Wireless: Bluetooth 4.0
  • Vibration: Yes
  • Battery life: 2 years
  • Water resistant: 100 meter depth
  • Operating system compatibility: Browser, Android, iOS
  • Other: LED lighting, ruggedized design

Rating: Warm. While the STB-1000 remains by far the most rugged and durable of the smartwatches, notification wearables fall short of impressive.

Qualcomm Toq: Smartwatch with Color E-Paper

qualcomm toq

  • Category: Smartphone or tablet notifications
  • Price: $269 until launch; $349 after launch.
  • Release date: Available
  • Sensory apparatus: EEG sensors, accelerometer
  • Wireless: Bluetooth 3.0
  • Vibration: Yes
  • Battery life: 5+ days
  • Water resistant: No
  • Operating system compatiblity: Android 4.0+
  • Other: Wireless charging, touchscreen

While the Qualcomm Toq didn’t debut at CES, I thought it necessary to include it in this roundup of wearable tech. Instead of providing metrics on health, it gives notifications, weather predictions and more. It’s unique in that it uses a highly advanced e-paper technology known as Mirasol. Mirasol offers similar battery efficiency as E Ink products, with the exception that it can operate in the same way as an LCD screen:  Full color and video graphics. Thanks to the low-powered screen, the Toq has more than a week of battery life (according to reports).

Had Qualcomm paired their technology with Bluetooth 4.0 and better internal components, it would have offered substantially better endurance. As it stands, Qualcomm’s Toq doesn’t particularly stand out from its competitors, except in pricing – it costs $349, making it the most expensive device in its category.

Holding it in my hand, it felt exactly like a miniature smartphone. Unfortunately, the Toq primarily provides notifications and a degree of control for your smartphone. While water-proof and semi-rugged, it fails to stand out in any serious way from its competition. On the other hand, it represents a wildly different, and technologically sophisticated device. Hopefully, the next iteration of the Toq will include Bluetooth 4.0, a richer sensor suite and wireless Qi charging, instead of its own (along with Samsung) wireless charging solution.

Rating: Warm. The high cost and lack of focus don’t allow the Toq to stand out from its competitors. While technologically sophisticated, it fails to crush similar notification gadgets.

Metria Informed Health: The Disposable Smartpatch

metria smartpatch

  • Category: Health oriented
  • Price: around $50
  • Release date: Q1 of 2014
  • Sensory apparatus: Heart rate, respiration, activity levels, sleep duration and more;
  • Wireless: Bluetooth 4.0
  • Vibration: No
  • Battery life: 7 days
  • Water resistant: Yes
  • Operating system compatibility: Android, iOS;
  • Other: Adheres to skin

The Metria smartpatch provides similar functionality to smartwatches, with a subtle, but important distinction: It’s disposable after a week. Its short-lifespan is by design. The smartpatch offers a low-cost method to aid doctors in the identification of potential health risks. We assume that most users would only need to wear one for a short period of time, so its short longevity shouldn’t cause much concern.

Looking at the device, it certainly gave off the impression of greater comfort than a smartwatch. The product manager mentioned that the adhesive is actually quite powerful and the device doesn’t stand a chance of slipping off. Of course, as a medical device you definitely wouldn’t want that happening. Considering that it offered slightly fewer sensors than the Basis Health Tracker, it offers less value to those looking to identify health problems over the long term.

Rating: Warm. While it’s potentially a revolutionary technology for the medical industry, the Metria Smartpatch isn’t something you’d just buy for the heck of it.


In my opinion, the notification watches don’t really offer much value to consumers. What can a notifications watch do that a smartphone doesn’t already provide? Some users might take advantage of their stealthy, low-profiles to text friends while in class or at meetings — but unless you enjoy slacking off, they’re superfluous and expensive. Conversely, health oriented smart devices can eventually replace expensive medical diagnostic equipment. Right now, they offer insight into your habits but in the near-distant future they could provide a great deal more benefit. Perhaps the singularity is approaching? If devices such as the Muse signal the future, our brains seem poised to become upgraded, so to speak, by our machines. As technological sophistication increases at an ever accelerating pace, the lines between our bodies and machines may blur. The potential of a technological singularity weighed on me. But before leaving the convention, I received a perverse reminder that flesh and metal might remains separate for some time.

As I returned to my hotel room, and fished through a clutch of business cards, I noticed something unusual: Someone had slipped a room card key, accompanied a room number jotted down on a piece of paper. Had someone tried to lure me to their hotel room? I had received dozens of cards that day and spoken with twice as many reps – the card provided a sad reminder that no matter how integrated we become with our machines, we still possess reckless physical desires.
