Health IoT: Scientists develop diet wearable – for your teeth

How Complete Beginners are using an ‘Untapped’ Google Network to create Passive Income ON DEMAND

tooth wearable tracks your diet

Scientists at the Tufts University School of Engineering have developed a wearable sensor that can stick to a single tooth to track a user’s diet, based on chemical changes in the mouth.

The sensor, which is mounted onto a tooth and communicates wirelessly with a mobile device, transmits information on the intake of glucose, salt, and alcohol. The subtle device has a 2mm x 2mm footprint and transmits information in response to an incoming radio signal.

The Tufts University research will soon be published in the journal Advanced Materials.

The technology has obvious preventative potential. Giving medical professionals insight into dietary habits could support the treatment of allergies, food intolerances, and eating disorders. It could also help dentists detect problems before they grow to be more serious.

A mouthful of personal data

The team at the Tufts University School of Engineering has say that, in future, sensors such as this could be able to detect and record of a wide range of nutrients, chemicals, and physiological states, well beyond the tracking of glucose, salt, and alcohol intakes.

“In theory, we can modify the bio-responsive layer in these sensors to target other chemicals – we are really limited only by our creativity,” said Fiorenzo Omenetto, corresponding author of the study and Professor of Engineering at Tufts.

“We have extended common RFID technology to a sensor package that can dynamically read and transmit information on its environment, whether it is affixed to a tooth, to skin, or to any other surface.”

The assumption is that miniature sensors such as this will work alongside mobile applications and be monitored by healthcare professionals. In the current climate, this may raise concerns among some citizens about data security and privacy.

There are obvious health benefits to round-the-clock dietary monitoring. But convincing the public that in-mouth wearables should be a mass market product may be the biggest challenge facing the technology.

Plus… Danish scientists develop sensor to detect dangerous drinking water

Danish researchers at Aarhus University have developed a sensor capable of detecting specific bacteria in drinking water, such as E. coli.

The sensor uses DNA-magnetic particle technology to seek out and isolate the bacteria using nano-sized magnets. The sensor can connect directly to a smartphone to provide a reading that detects a single cell of E. coli in less than one hour. Traditional detection methods require lab tests and can take several days.

The research team is aiming to have a commercial product ready for market within three years.

Brushing your teeth with a smart toothbrush is unnecessarily arduous

My family freaked out when electric toothbrushes came out. They’re passionate about oral health, and, finally, they could own a tool that’s more on par with a dentist’s. So everyone in my family now has an electric toothbrush.

The excitement hasn’t continued with the announcement of smart toothbrushes. Do we need a Bluetooth-connected toothbrush? Will that really enhance the mundane brushing experience?

I brought the Colgate E1, the Sonicare DiamondClean Smart, and the Playbrush on Circuit Breaker Live to find out. Unlike the other two brushes, the Playbrush is just a Bluetooth dongle that fits any regular, non-electric toothbrush. I’ve been testing the Sonicare for a few months at home, and within a week, I had already given up on…

This new dinosaur species had massive, scissor-like teeth

A 70-million-year old dinosaur species possessed massive, scissor-like chompers that it probably used to gnaw through the tough, fibrous leaves of ancient palm trees. The discovery might help explain how multiple species of vegetarian dinos could co-exist in prehistoric Europe: this new dinosaur likely ate the parts of plants that no one else wanted.

The toothy dinosaur, described this week in the journal Scientific Reports, was discovered in the south of France among a jumble of bones from other dinosaurs and reptiles. Called Matheronodon provincialis, all that remains of this new species is an 8-inch long chunk of its right upper jaw, and a few loose teeth that may have come from other individuals. The researchers estimate based on…

Scientists Have Discovered This Drug Fixes Cavities and Regrows Teeth

Goodbye, Fillings

Dental fillings may soon be left in the ash heap of history, thanks to a recent discovery about a drug called Tideglusib. Developed for and trialled to treat Alzheimer’s disease, the drug also happens to promote the natural tooth regrowth mechanism, allowing the tooth to repair cavities.

Tideglusib works by stimulating stem cells in the pulp of teeth, the source of new dentine. Dentine is the mineralized substance beneath tooth enamel that gets eaten away by tooth decay.

Teeth can naturally regenerate dentine without assistance, but only under certain circumstances. The pulp must be exposed through infection (such as decay) or trauma to prompt the manufacture of dentine. But even then, the tooth can only regrow a very thin layer naturally—not enough to repair cavities caused by decay, which are generally deep. Tideglusib changes this outcome because it turns off the GSK-3 enzyme, which stops dentine from forming.

In the research, the team inserted small, biodegradable sponges made of collagen soaked in Tideglusib into cavities. The sponges triggered dentine growth and within six weeks, the damage was repaired. The collagen structure of the sponges melted away, leaving only the intact tooth.

Thus far, the procedure has only been used in mouse teeth. Yet as King’s College London Dental Institute Professor and lead author Paul Sharpe told The Telegraph, “Using a drug that has already been tested in clinical trials for Alzheimer’s disease provides a real opportunity to get this dental treatment quickly into clinics.”

He added, “The simplicity of our approach makes it ideal as a clinical dental product for the natural treatment of large cavities, by providing both pulp protection and restoring dentine.”

The First Fully Automated Toothbrush is Here. And it Cleans Your Teeth in 10 Seconds.

Say hello to Amabrush, the world’s first automatic toothbrush, and goodbye to brushing your teeth for minutes at a time twice a day. Amabrush resembles a mouthguard with soft silicone bristles in it, and it is magnetically attached to a round handle. Put the mouthpiece in, and don’t worry about the toothpaste, it’ll do that for you. It will then go to work, brushing your teeth in the way that your dentist tells you to, in every location in your mouth, all at the same time.

Using this device, brushing all of your teeth to perfection only takes about 10 seconds from start to finish, so it’s no surprise that the Amabrush is doing really well on Kickstarter. As this article is being written, they have 25 days to go and have already raised $ 935,891, surpassing their $ 56,972 goal.

The Amabrush is just one more example of automation doing what it does best: taking over mind-numbingly dull daily tasks, freeing up humans to think about and do more compelling things. Whether it’s a significant step in automation, like self-driving cars, or just a piece of the puzzle, it’s all progress in the same direction. By extension, automation can free us from repetitive, dull jobs and free us up for more challenging careers, hobbies, passions, etc. All we have to do is be willing and ready for this change to happen.

What if you could brush your teeth in 10 seconds through the power of crowdfunding?

There are a small set of facts here, but they have profound implications for how we live our lives.

  1. There’s a new Kickstarter project called Amabrush.
  2. It’s shaped like a mouthguard, and it brushes your teeth all at once in 10 seconds.
  3. A removable handle makes the whole setup look like an adult pacifier. It’s what vibrates the “brush” mouthpiece and dispenses the toothpaste.
  4. The handle uses proprietary toothpaste capsules.

Notice what’s missing? That’s right, there’s no app. How am I supposed to set up an IFTTT recipe to tweet @ my mom every time I brush?

Otherwise, this is peak Kickstarter: a pod-based business model ($ 3 or so for about a month’s supply of toothpaste) due to an unconventional form factor (apparently the toothpaste…
