Such systems or devices may be utilized. Such devices are required by millions of users worldwide, such as by medical personnel or by self-employed by the users in a variety of scenarios such as medical check-ups, patient-care or hospitality, self-diagnosis via user and so forth. Conventionally, the measurement of the blood analyte level (such as, blood glucose) is done in an invasive manner such as, finger-prick methods that require a sample of blood of a user, for further testing thereof. To solve the aforementioned problem, different devices and/or methods are proposed as non-invasive, including, but not limited to, methods for blood analyte level measurements via laser exposure such as, surface plasmon resonance (SPR), optical polarimetry etc., methods for blood analyte level measurements via different spectroscopy methods such as, near infrared spectroscopy, optical coherence tomography, raman spectroscopy, and other similar methods for blood analyte level measurements. However, such methods and systems are highly complex and expensive to manufacture and thus, scaling for the general population is not feasible. Consequently, a need for a simple, effective and cost-effective device, system or method for measuring the blood analyte level in a non-invasive manner is developed.
