Abstract

Provided herein is a non-invasive, continuous biometric sensor system for determining a characteristic of a state of a user based on a value of a biomolecule. The system includes a biomolecule sensing device and attachment structure for coupling the sensor to the body. The biomolecule sensing device is configured for generating digital signal read data pertaining an effect of a biomolecule on the tissues of the body such as by employing Near Infrared Spectroscopy (NIS) techniques. Accordingly, the sensing device includes electronic sensing components having a photoemitter for directing electromagnetic radiation into the tissue of a body, the tissue suspected of being affected by the presence of the biomolecule, and a photoreceiver for receiving electromagnetic radiation reflected back from the tissue. The reflected electromagnetic radiation may then be used by the system to determine a presence and/or concentration of a biomolecule of interest and/or its effect on the user.

A biometric sensor system for determining a characteristic of a state of a user based on a value of a biomolecule within a body tissue, the system comprising:

an attachment structure having an elongated surface member, the elongated surface member having an inner portion and an outer portion, the outer portion being defined by a perimeter including a top surface and a bottom surface, and the inner portion being defined by an opening, the bottom surface the perimeter including an attachment element for attachment to the body tissue of a user;
an encasement member having a plurality of horizontally extended flat surfaces including a first flat surface and a second flat surface, the plurality of flat surfaces being offset from one another by a bounding surfaces, the bounding surface being positioned substantially normal to the first and second flat surfaces, together the first flat surface and the bounding surface forming a dome, the dome defining an opening of a first cavity of the encasement member, and the second flat surface forming an attachment interface extending laterally outwards from the dome by which the encasement member may be coupled to the attachment structure in a manner that the opening of the cavity is coincident with the opening of the attachment structure;
and
a biomolecule sensing device configured for being inserted through the opening of the attachment structure and dome so as to be encased within the encasement member, the biomolecule sensing device comprising:
a housing having a top member and a bottom member, each top and bottom member having an extended planar surface and a perimeter surface, the perimeter surface including a bounding wall that extends substantially normal to an outer edge of the extended planar surface such that when the top member is coupled to the bottom member a cavity is formed therebetween, the cavity being defined by interior portions of the extended planar and perimeter surfaces, together the top and bottom member bounding walls having corresponding latching mechanisms by which the top and bottom members may be coupled together so as to form the cavity of the housing, the bottom member including a window positioned within the second flat surface, the window being aligned with the opening of the attachment structure when the biomolecule sensing device is encased within the encasement member, and
a biomolecule sensor unit for detecting a characteristic of a bodily response due to a presence of the biomolecule within the body tissue, the biomolecule sensor unit comprising:
a printed circuit board having a sensor array coupled therewith, the sensor array including a sensor unit having one or more photoemitters and one or more photoreceivers, each being arranged on the printed circuit board within in the housing proximate the transparent window opposite the user's body tissue, the one or more photoemitters configured to illuminate, at a predetermined frequency and interval of light, the user's tissue below the transparent window, and each of the one more photoreceivers configured to receive a return of the light reflected back from the user's tissue below the transparent window and to generate a return signal in response to collecting the reflected light, the printed circuit board further comprising processing unit configured for processing the return signal to determine the characteristic of the state of the user based on the return of the light reflected back from the user's tissue.
