Remember the Twitter tooth implant, the handy little (speculative) device that spied on your drinking, eating and smoking habits? The implant made its first debut in real life with a "tattoo" consisting of electrical sensors. Now, a team of Taiwanese researchers have gone beyond surface electronics to create a whole implantable tooth, complete with a tiny accelerometer.
Because everything we do with our mouths, from chatting to chewing, produces a unique motion profile, the team was able to predict what participants' mouths were getting up to with close to 95% accuracy. Future prototypes of the "wearable oral sensory system" will include Bluetooth (no pun intended) to wirelessly transmit data to a cell phone or computer. Just imagine waking up to a chiding letter from your parents when they find out you've been smoking, or a worried note from your doctor if she suspects you're coming down with a cold. Of course, you can always talk to yourself if you want to fake a healthy dose of social interaction.
