Researchers at National Taiwan University have developed a tiny sensor that can be embedded into a tooth cavity, dentures, or braces to stop you from lying through your teeth, in a manner of speaking. The sensor is able to detect with nearly 94 percent accuracy common oral activities such as chewing, drinking, speaking, and coughing. The end goal of something like this is to enable healthcare applications, such as fluid or intake monitoring, or to tell if a patient has been smoking.

There have been other similar sensors before, but rather than being placed on the body, this one goes inside the body, right in the mouth. According to the researchers who developed the device, the advantage of this placement is that it's able to more accurately capture the motion of oral activities.

"Because the mouth is an opening into human health, this oral sensory system has the potential to enhance oral-related healthcare monitoring applications such as dietary tracking," the researchers say.

The sensor is an accelerometer that analyzes unique mouth movements for different oral activities. The breakout board that it's attached to measures 4.5mm by 10mm, small enough to be placed inside a tooth or dental equipment. It's coated with dental resin to protect it from saliva. While the prototype is a pretty barebones system, the researchers say in actual deployment, it would also include a small Bluetooth radio to wirelessly transmit data to a nearby mobile phone for data analysis and oral activity recognition.

That. Is. Disgusting. That's bigger than the tooth! If a dentist ever puts one of these in me, there will be Hell to pay...

I agree this would not be very appealing to me....or most people everywhere.

That would drive anybody nuts if it was in your mouth!

Just because you ~can~ build something, doesn't mean that you should,.......

Dogs are great judges of character, and if your dog doesn't like somebody being around, you shouldn't trust them.

ugh, you guys ever get a blackberry seed stuck in your mouth? Or a piece of steak? Imagine that stuck like that for however long that thing stays in your mouth... It would be so annoying I think that I would begin debating in my mind re-enacting the famous scene from castaway, involving the pair of figure skates

"It was terribly dangerous to let your diet wander when you were in any public place or within range of a telescreen or a tooth. The smallest thing chewed could give you away. A nervous tic, an unconscious look of anxiety, a habit of muttering to yourself, a jaw spasm--anything that carried with it the suggestion of food, of having something to eat. In any case, to wear an improper expression of chewing on your teeth...; was itself a punishable offense. There was even a word for it in Newspeak: Toothcrime..."

Orwell1984, I absolutely loved that book. 1984 was the first thing I thought of when I read the title of this article.

Unbelievable! This is INSANITY to put non-stop radiofrequency microwave radiation from Bluetooth directly into the mouth.

Bluetooth operates at 2.45 GHz - the same as your MICROWAVE OVEN!

Please watch this video to see and hear the radiation that comes off from Bluetooth. http://www.youtube.com/watch?v=M4RWGImXwGI

I agree that this is dangerous to the individual. There are now thousands of credible research studies that prove serious health damage (ie. brain barrier leaks, cancer, electric hypersensitivity, headaches, tinnitus, etc.). You can find many of these studies at: www.bioinitiative.org. To put a radiation producing device in your mouth is insane!
