A non-invasive biometric sensing and monitoring device 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 encasement member having a set of opposed surfaces offset from one another by a bounding member, a first of the opposed surfaces forming a top surface and a second of the opposed surfaces forming a bottom surface, together the plurality of opposed surfaces and boundary member bounding a cavity, the cavity configured for retaining one or more components of the biometric sensing and monitoring device;
- an extended substrate layer positioned within the cavity and being configured for effectuating a coupling between one or more of the retained components:
- a frequency synthesizer, coupled to the substrate and being configured for generating a signal to be transmitted;
- a microwave structure unit positioned on the extended substrate layer and being coupled to the frequency synthesizer, the microwave structure unit having a first port and a second port, the first port being separated from the second port by an extended segment of a microwave structure of the microwave structure unit, the extended microwave structure segment forming a curvilinear pathway between the first and second ports, each first and second port including a positive and a negative lead separated from one another by a first distance, the first port coupling the frequency synthesizer to the extended microwave structure and being configured for receiving the signal and for transmitting a first portion of the signal linearly forward in a confined manner along the curvilinear pathway of the microwave structure from the first port to the second port, and further being configured for transmitting a second portion of the signal radially forward in a non-confined manner from the first port to the second port so as to produce both a confined signal portion and a non-confined signal portion, the second port being configured for receiving both the confined signal portion and the non-confined signal portion;
- a power detector positioned on the extended substrate layer and being coupled to the second port of the microwave structure unit, the power detector being configured for receiving at least a portion of each of the confined and non-confined signal portions, and in response thereto generating both confined and non-confined transmission response data;
- an analog to digital converter coupled to the power detector and being configured for converting an analog signal portion of the confined and non-confined transmission response data into digital confined and digital non-confined transmission response data;
- and
- a control unit for directing operations of the frequency synthesized, power detector, and analog to digital converter in accordance with one or more generated or received instructions.
