A sensor embedded in your tooth could tell doctors if you have defied medical advice to give up smoking or to eat less!
Built into a tiny circuit board, the sensor includes an accelerometer that transmits data to a smartphone. So from each tell-tale jaw motion pattern, the software can work out how much chewing, teeth grinding, smoking, coughing, talking or (…okay I’ll stop there!) that you are doing.
The device can be fitted into dentures or a dental brace, and the team at the National Taiwan University in Taipei plan to miniaturise it further to fit into a cavity or crown. Results so far look promising, with the system having recognised ‘oral activities’ correctly 94 per cent of the time in tests to date. New Scientist and IEEE Spectrum have both covered the story.
It kind of takes ‘wearables’ into a whole new sphere! Don’t you think?
