Q-Blood Sense: Coherence-Based Molecular Signal Isolation A Non-Contact Engineering Framework for Blood Composition Estimation

Q-Blood Sense is a conceptual engineering framework for non-contact exploration of blood-related signal features using coherence-based digital lock-in techniques. The system aims to detect structured modulations in weak bio-potential fields associated with collective ionic and dielectric behaviors within blood vessels. The approach emphasizes engineering feasibility and signal-processing investigation rather than biochemical measurement or clinical diagnosis.
