Determining food identities with intra-oral spectrometer devices

An intra-oral device, comprising:

• a processor;
• a computer-readable medium storing instructions which, when executed by a processor, cause the processor to perform operations, the operations comprising:
• detecting an act of eating via a sensor of the intra-oral device;
• activating a spectrometer of the intra-oral device to measure at least one property of at least one component in a sample of a food, when the act of eating is detected;
• and
• transmitting the at least one property of the at least one component in the sample of the food to a wireless device via a wireless transmitter of the intra-oral device;
• and
• a chargeable battery for delivering electrical power to the intra-oral device, wherein the chargeable battery is charged via a motion of a mouth.

An intra-oral device comprising:

• a sensor for detecting an act of eating;
• a spectrometer for measuring at least one property of at least one component in a sample of the food when the act of eating is detected;
• a wireless transmitter for transmitting the at least one property of the at least one component in the sample of the food;
• and
• a chargeable battery for delivering electrical power to the intra-oral device, wherein the chargeable battery is charged via a motion of a mouth.

A method comprising:

• delivering, via a chargeable battery, electrical power to an intra-oral device, the chargeable battery is charged via a motion of a mouth;
• detecting, via a sensor, an act of eating;
• activating, via a processor, a spectrometer of the intra-oral device to measure at least one property of at least one component in a sample of a food, when the act of eating is detected;
• and
• transmitting, via the processor, the at least one property of the at least one component in the sample of the food to a wireless device via a wireless transmitter of the intra-oral device.
