Abstract: A system for monitoring blood content, comprising an integrated laser circuit mounted on a tooth, an integrated detector circuit mounted on the tooth at a different location from the integrated laser circuit and a power supply coupled to the integrated laser circuit and the integrated detector circuit.

Abstract: Disclosed herein is a device and method for a smart-tooth glucose monitoring device. The device is created in response to the desire for an accurate and non-invasive or partially-invasive monitoring device as an alternative to current methods of the glucometer lancet and strips. The device consists of a tooth and its pulp chamber to achieve direct measurement of blood, an optic source and sensors that measure the wavelengths emitted by the optic source. The tooth is embedded with a flexible circuit with a monochromatic light as an optic source with different sensors such as PZT transducer and photodiode within a modified porcelain crown. The monochromatic light pulses passes through the tooth and its pulp chamber and the photoacoustics measured by the sensors which can then be utilized to determine glucose concentration in the blood.
