Wearable Sweat Sensor A real time Analyzer of your body biochemistry

Wearable biosensors analyse your sweat and send health reports to smartphone in real time

Wearable sensors is the new hot topics now.  Earlier in this blog I shared how the smartphone and innovative wearable technology will change the future of healthcare industry.  A recent publication in Nature magazine reveals the true existence of a wearable sensors, which can analyze body biochemistry from your sweat and send the report to your smartphone in real time.  They call it as wearable sweat sensors.

This is a flexible plastic patches, which can read the molecular composition of sweat and send the real time analysis report to a smartphone. It could provide an alarm that you need to take some medication or you are getting dehydrated and needs to drinks some water.

Several labs have been developing sensors for sweat, which contains a multitude of electrolytes and metabolites — the final products of the body’s biological processes (for example, the lactic acid that builds up after exercise). But these sensors have tended to measure only one component of sweat at a time, and generally cannot transmit their measurements in real-time.

Putting together existing advances in wearables technology, Javey’s team made the sensors from a flexible electronics board joined to a flexible printed plastic sensor array, which can detect glucose, lactate, sodium, potassium and body temperature. When the sensors come into contact with sweat they generate electrical signals that are amplified and filtered, and then calibrated using skin temperature. The data are then wirelessly transmitted to a smartphone.

Challenges and Conclusion

There are still many challenges to overcome before you can expect to buy a sweat sensor incorporated into a wearable fitness band. For one thing, scientists aren’t used to working with such tiny quantities of fluid, and people aren’t always sweating.

Sweat sensors will never be as accurate as blood tests, which are the “gold standard”. Our bodies closely control the molecular composition of our blood, but the content of our sweat is more variable and is sometimes influenced by microbes on our skin — so the medical relevance of the information that sweat provides will need to be rigorously tested. However, sweat does have an advantage: taking blood samples with a needle is not a practical means of assessing health on a minute-by-minute basis.

In time, the researchers hope to incorporate more sensors that might provide an even deeper picture of what’s happening in the body. Some research suggesting that certain biomarkers in sweat may correlate with symptoms in people with depression.  By looking at those other chemicals we may be able to get information about the mental health of an individual.

Pebble Time's iOS app hasn't been approved by Apple yet

The iOS faithful who already received their shiny new Pebble Time smartwatches are likely more than a little disappointed. The wearable is shipping to Kickstarter backers, but there's one big problem: the Pebble Time Watch iOS app hasn't been approved by Apple yet. Despite pushing minor bug fixes for approval on May 22nd, and asking that the folks in Cupertino fast-track the request, the software needed to get the gadget up and running isn't in the App Store. Even though a version of the app was approved on May 18th, it can't be released "due to quirks in the App Store submission process and rules."

The company says it considered adding features for the Time to the existing Pebble iPhone app, but a new version of that software has been waiting on approval for over a month. For now, Pebble advises owners to find a pal with an Android device to sort the initial setup, and to bug Apple about the issue. You still won't be able to leverage any apps that require the device to be paired with a smartphone, though, and that's a major bummer.

We reached out to Apple on the matter and we'll be sure to update this post if he hear back.

SmartBand 2 wearable from Sony is with heart rate monitor

Sony reveals SmartBand 2 wearable with heart rate monitor

Companies often unveil new a product by putting an executive on stage and making them say nice things about it. Other times, they'll launch a fancy webpage and put up glamorous photos of whatever they're launching. Sony, on the other hand, appears to be unveiling a new product today by accidentally publishing information about it in the Play Store. Which, I suppose, still gets the job done.

The slip-up makes it appear that Sony is making a new version of the SmartBand, its wearable that's meant to help people track what's going on in their life. This new one, called the SmartBand 2, adds a heart rate monitor, which should make it function much better as a fitness tracker. It also has a brand new app, which is what appears to have gone live in the Play Store early and revealed this information. The new app looks a lot better than Sony's dedicated Lifelog app, but you'll apparently still need to download both to get the full experience.

Like the existing model, the SmartBand 2 is also able to track steps and sleep, alert wearers of incoming messages on their phone, and vibrate when they have an alarm. It also has a dedicated button you can press to take a snapshot of all the data it has at the given moment, which is supposed to help you record meaningful moments in your life. That seems like a bit of a stretch, but it certainly sets the band apart from the many similar offerings already out there. It's not stated when the SmartBand 2 will be released, but given that its app is out there, it seems like it should be pretty soon.
