Google patents a wearable odor-sensing (and masking) device


Like a Glade Plug-in for your armpits? 


While most of the wearable devices on the market today have been geared towards tracking activity levels, monitoring sleep habits or even analyzing fitness routines, we may be on the cusp of a new era in body-adorned gadgetry. That’s because Google has received a patent for a movement-tracker that activates a web-connected air freshener to emit a fragrance to mask any offending odors caused by physical activity. In other words, you’ll no longer need to smell your armpits to ensure that you’re free of B.O.

How it works is pretty self-explanatory. If the device, shall find you on the smelly side, it will give off a nice-smelling fragrance to deoderize you. What’s more, the gizmo also plugs into your social media accounts to help steer clear of any friends who may be in your vicinity. If someone is nearby, the device will send the not-so-fresh-smelling wearer a map with a route to navigate around those folks. The one-of-a-kind gadget is also equipped with a tiny fan to ensure the fragrance gets to the right place.

“When a user is wearing the fragrance emission device and begins to exert himself or herself, an activity module within the device may detect the physical exertion. The activity module may detect a rise in sweat levels, an increase in body odor or body temperature, or any other parameter that may indicate the user is exercising or otherwise exerting themself,” Patent No. 8,950,238 reads.

When the activity module determines that the user is performing a physical activity, it alerts the device’s built-in predictor. This predictor then uses the information provided by the activity module to predict when the user will generate body odor in the future, and when a fragrance will need to be applied to the user.

“For the purposes of brevity, the material applied to the user will be described as a fragrance, however, the material applied may also be an odor neutralizer, which would serve to neutralize or eliminate the body odor generated by the user instead of covering it up with a fragrance. In some embodiments, the predictor may also use information stored within the device regarding past instances where a fragrance was emitted, combine that information with the current information supplied by the activity module, determine when body odor will be generated by the user, and dispense an appropriate amount of fragrance at an appropriate time,” the patent document explains.

Once the predictor determines when the user will begin to generate body odor, an optional alert module located within the device may alert the user of the situation and let the user know when the fragrance will be emitted. The user will then have the opportunity to override the impending fragrance emission, based on the current circumstances of the user. This will particularly come in handy if, say, you are planning on showering immediately after a high-intensity workout.

“Should the user choose to reject the fragrance emission, a suppressor located within the device will cancel the scheduled fragrance emission such that the material dispenser will not dispense the fragrance at the scheduled time. Should the user choose to accept the fragrance emission instead, the suppressor will not cancel the scheduled fragrance emission, and the material dispenser will dispense the fragrance at the scheduled time.”

Of course, this doesn’t mean that the Google concept will actually make it to product form. Though, given the proliferation of fitness-focused apps and wearables, it does mean that the world is becoming more active and therefore will get a bit stinkier, too. Interested in learning more?

InBody Band puts body composition at your fingertips


Now you can measure your body fat, muscle mass and so much more anytime, anywhere. 


It was nearly impossible to walk around the CES 2015 show floor without coming across some sort of fitness tracker or smartwatch. In such a competitive market, companies are continually looking for new ways to differentiate themselves from the wearable pack. And, while a vast majority of fitness trackers let you monitor caloric intake, steps and sleeping habits, a new gadget has set out to measure a user’s body composition as well.

BodyBand

Recently launched on Kickstarter, the InBody Band is a snap-on device that features a simple touchscreen display and four sensors located on its front and back. Users simply place their fingers on the front-facing sensors and, combined with the data from your wrist, retrieve a reading in just seconds. The wearable uses a series of electronic pulses, and some proprietary algorithms, to analyze metrics such as muscle mass index and body fat percentage, while simultaneously clocking heart rate and tracking movement with the aid of its built-in 3D accelerometer.

Like other smart bands available today, the device can monitor real-time activity and sleep habits, as well as help set specific goals to achieve. Furthermore, the InBody Band is capable of distinguishing between walking and running, thus providing more precise information and feedback on your daily routine. It is also water-resistant enough to withstand some hand-washing or a quick shower even, however is not recommended for the pool or any other aquatic activities.

Create a color-changing sweatshirt with a potentiometer and GEMMA


Stay warm while looking cool! 


While we’ve covered a number of Becky Stern’s slick wearable creations in recent months, the timeliness of this one couldn’t be better for our friends in the Northeast as they battle these bitter cold months. Thanks to her latest tutorial, Makers can now easily create their own color-changing NeoPixel hoodie using a soft potentiometer, conductive thread, some tiny LEDs and an Adafruit GEMMA (ATtiny85).

sensors_textile-potentiometer-hoodie-01

Conductive thread is used to connect the potentiometer to the wearable platform board, which is sewn to the zipper on the front of the sweatshirt. This allows for the use of the drawstring to perform a sliding action. The sensor’s ribbon was divided in half, leaving two pieces: one for the pull tab, the other to slide along.

sensors_demo-textile-potentiometer-hoodie

“The yarn in the sensor has a high resistance that GEMMA can measure with its analog input. The charm moves along its length, changing the amount of yarn connected to the input,” Stern explains.

Stern notes that a Maker could also couple a temperature control action of zipping/unzipping the hoodie with the LED color-changing effect. However, for simplicity sake of the demonstration, she decided to keep them separate.

sensors_textile-pontentiometer-hoodie-demo

With a simple Arduino sketch and stitching of the NeoPixels tasked with altering colors, you’re just about ready to go. The code uses the changing value of the slide sensor to adjust the blinking speed of GEMMA’s onboard LED. Slide the sensor and watch the LED blink faster or slower.

Before completing the project, a Maker must cut a small hole in the upper inside edge of the hoodie’s front pocket, and thread through a JST extension wire for the AAA battery pack. Store the batteries inside the pocket, and run the extension cable up through the front facing to plug into GEMMA’s JST port. And, voila!

Building a Pro Trinket smartwatch


Don’t feeling like buying a smartwatch or waiting around for Apple’s launch in April? You can make your timepiece instead! 


Maker James Chin has recently been working on a new watch, controlled by a Pro Trinket (ATmega328) and a real-time clock. The DIY wearable is equipped with a potentiometer under the OLED screen and a momentary button to control the watch.

james-chin-diy-smartwatch

“But what I think is the best part is on the right. There are female headers that allow me to connect multiple ‘modules’ to it, like the LED shown in the picture.”

At the moment, the Maker has included a white LED, a black light LED, as well as with a switch along the side that he used to play Pong. Moving ahead, Chin also plans on adding a TV-Be-Gone, an XBee, an accelerometer, and some analog sensors. Sounds pretty awesome to us!

We look forward to seeing future iterations of this build. Great find, Adafruit!

Report: 720,000 Android Wear devices shipped in 2014


Motorola’s Moto 360 led the pack in sales for Android Wear devices last year, a new report reveals.


According to the latest report from research firm Canalys, over 720,000 Android Wear-based devices were shipped in 2014, making up 16% of the total 4.6 smart wearable bands sold. Over the 12-month span, the [MXT112S powered] Motorola Moto 360 led the pack among other companies, while LG’s round G Watch R performed significantly better than its original G Watch, and Asus and Sony entered the market with their own Android Wear devices.

Outside of the Android ecosystem, Pebble shipped a total of one million units from its 2013 launch through to the end of 2014. Continual software updates, an increase in apps, and price cuts in the fall were among the key factors in helping to maintain strong sales in the second half of the year. Meanwhile, Fitbit remained the global leader in the basic wearable band market.

Following a completely different strategy to other vendors, Xiaomi shipped over a million units of its Mi Band, the colorful and affordable basic device. As Canalys notes, this included one day of sales of over 103,000 units.

“Though the Mi Band is a lower-margin product than competing devices, Xiaomi entered the wearables market with a unique strategy, and its shipment volumes show how quickly a company can become a major force in a segment based solely on the size of the Chinese market,” explained Canalys Research Analyst Jason Low.

All eyes will now turn to Apple as the market awaits the arrival of its new smartwatch this April. The research firm points out that the product will dramatically grow the market for smart bands and wearables overall.

“Apple made the right decisions with its WatchKit software development kit to maximize battery life for the platform, and the Apple Watch will offer leading energy efficiency,” said Canalys Analyst Daniel Matte. “Android Wear will need to improve significantly in the future, and we believe it will do so.”

“Ironically, it could be the Apple Watch launch that determines the future of Google’s platform, and the degree to which OEMs back it,” writes TechCrunch’s Darrell Etherington. “While it’s designed as a competitor to what Android is doing with its own wearable platform, its presence in the press and in consumer minds could encourage more Android device owners to look around for their own equivalent, considering the other option is switching platforms altogether. Even if initial comparisons greatly favor Cupertino’s wrist-based computer, long-term, Android Wear could benefit.”

Android Wear became much more plentiful in the latter half of 2014. However, the numbers likely have OEMs watching and waiting to see how the market evolves from here, given that there’s already price pressure on some of these.

A look at some of today’s wearable microcontrollers


This list is sew awesome!


Created by Leah Buechley of MIT, and introduced commercially with SparkFun back in 2007, the LilyPad was the first board to feature sew-through contacts for stitching soft circuits. Since then, a number of “ready-to-wear” electronics platforms have emerged, each of which have helped usher in a new generation of textiles that look to redefine wearable technology. In fact, a recent Gartner report revealed that the emergence smart garments will potentially disrupt the market. So much so that embedded clothing shipments are projected to rise from a mere 0.1 million units in 2014 to 26 million units in 2016.

As first noted by MAKE: Magazine’s Boris Kourtoukov, “there’s a plethora of options” when it comes to these microcontrollers. What’s more, they all possess one common trait: they’re powered by Atmel. These so-called body boards are now giving Makers the ability to easily (and affordably) produce their own projects in ways that otherwise would have been unimaginable.

So, without further ado, here’s a look at some of today’s most prominent boards ready for adornment.

Trinket

adafruit-trinket-5v

Trinket goes to show that big things really can come in small packages. In fact, the tiny MCU is one of the lowest-cost Arduino IDE programmable boards on the market today. Adafruit designed a USB bootloader so Makers could easily plug it into any computer and reprogram it over a USB port just like an Arduino. It comes in two different versions: 3V and 5V. Both work the same, but have different operating logic voltages.

Pro Trinket

MFG_2000

A bigger sibling of the aforementioned board, this 5V unit combines everything you love about Trinket along with the familiarity of the common core found in Arduinos. It’s like an Arduino Pro Mini with more pins along with built-in USB. The Pro Trinket, which still only measures 1.5″ x 0.7″ x 0.2” in size, features 18 GPIO, two extra analog inputs, 28K of flash, as well as 2K of RAM. Like its older brother, the MCU has onboard USB bootloading support and Optiboot support, so Makers can either program their Pro Trinket over USB or with a FTDI cable just like the Pro Mini. (Recently, paying homage to our friends at Hackaday, the Adafruit crew even unveiled a Hackaday.io branded board — black solder mask, Jolly Wrencher and all. And, it’s stunning.)

Ready to wear sensor hubs


Majeed Ahmad explores the latest sensor hub offerings for wearable devices.  


By Majeed Ahmad

Atmel has beefed up its sensor hub offerings for wearable devices with SAM D20 Cortex M0+ microcontroller core to add more functionality and further lower the power bar for battery-operated devices. The SAM D20 MCUs offer ultra-low power through a patented power-saving technique called “Event System” that allows peripherals to communicate directly with each other without involving the CPU.

Atmel is part of the group of chipmakers that use low-power MCUs for sensor management as opposed to incorporating low-power core within the application processor. According to market research firm IHS Technology, Atmel is the leading sensor hub device supplier with 32 percent market share.

Sensor hubs are semiconductor devices that carry out sensor processing tasks — like sensor fusion and sensor calibration — through an array of software algorithms and subsequently transform sensor data into app-ready information for smartphones, tablets and wearable devices. Sensor hubs combine inputs from multiple sensors and sensor types including motion sensors — such as accelerometers, magnetometers and gyroscopes — and environmental sensors that provide light level, color, temperature, pressure, humidity, and many other inputs.

Atmel has supplied MCU-centric sensor hub solutions for a number of smartphones. Take China’s fourth largest smartphone maker, Coolpad, which has been using Atmel’s low-power MCU to offload sensor management tasks from handset’s main processor. However, while still busy in supplying sensor hub chips for smartphones and tablets, Atmel is looking at the next sensor-laden frontier: wearable devices.

SAM D20 Evaluation Kit

SAM D20 Evaluation Kit

Wearable devices are becoming the epitome of always-on sensor systems as they mirror and enhance cool smartphone apps like location and transport, activity and gesture monitoring, and voice command operation in far more portable manner. At the same time, however, always-on sensor ecosystem within connected wearables requires sensor hubs to interpret and combine multiple types of sensing—motion, sound and face—to enable context, motion and gesture solutions for devices like smartwatch.

Sensor hubs within wearable environment should be able to manage robust context awareness, motion detection, and gesture recognition demands. Wearable application developers are going to write all kinds of apps such as tap-to-walk and optical gesture. And, for sensor hubs, that means a lot more processing work and a requirement for greater accuracy.

So, the low-power demand is crucial in wearable devices given that sensor hubs would have to process a lot more sensor data at a lot lower power budget compared to smartphones and tablets. That’s why Atmel is pushing the power envelope for connected wearables through SAM D20 Cortex M0+ cores that offload the application processor from sensor-related tasks.

The SAM D20 devices have two software-selectable sleep modes: idle and standby. In idle mode, the CPU is stopped while all other functions can be kept running. In standby mode, all clocks and functions are stopped except those selected to continue running.

Moreover, SAM D20 microcontroller supports SleepWalking, a feature that allows the peripheral to wake up from sleep based on predefined conditions. It allows the CPU to wake up only when needed — for instance, when a threshold is crossed or a result is ready.

The SAM D20 Cortex M0+ core offers the peripheral flexibility through a serial communication module (SERCOM) that is fully software-configurable to handle I2C, USART/UART and SPI communications. Furthermore, it offers memory densities ranging from 16KB to 256KB to give designers the option to determine how much memory they will require in sleep mode to achieve better power efficiency.

Atmel’s sensor hub solutions support Android and Windows operating systems as well as real-time operating system (RTOS) software. The San Jose–based chipmaker has also partnered with sensor fusion software and application providers including Hillcrest Labs and Sensor Platforms. In fact, Hillcrest is providing sensor hub software for China’s Coolpad, which is using Atmel’s low-power MCU for sensor data management.

The company has also signed partnership deals with major sensor manufacturers — including Bosch, Intersil, Kionix, Memsic and Sensirion — to streamline and accelerate design process for OEMs and ensure quick and seamless product integration.
