Provided herein is a non-invasive biometric sensing and monitoring device that may be employed in a non-invasive method with the potential for comprehensive analysis and data processing. The non-invasive biometric sensing and monitoring device may be employed for determining a characteristic of a state of a wearer using the device based on a value of a biomolecule within a body tissue of the user. The device may include a housing for retaining one or more components of the biometric device. The components may may include a substrate, such as a printed circuit board, and may further include one or more of an signal generator, a microwave structure based sensor unit, a filter unit, a receiver component, an analog to digital converter, a control unit, one or more buffers, a communications module and controller as well as an analytics system.
