Abstract: The current invention is associated with a wearable mobile health monitoring device that provides high-fidelity physiological signal detection. Traditional health wearables are fundamentally limited by the use of traditional sensors, such as photoplethysmography (PPG), which are not sensitive enough to provide pre-symptomatic screening and are highly susceptible to motion artifacts that contaminate data in daily life. This invention overcomes these important limitations by integrating a nitrogen-vacancy (NV) diamond magnetometer, a solid-state, room-temperature quantum head, into a small, power-controllable design. This quantum implementation provides picotesla level sensitivity in a ruggedized package that can be used in ambulatory conditions, in contrast to the high-sensitivity sensors of the previous art that needed cryogenic cooling. The system is intended for non-invasive detection of the tiny biomagnetic fields of order of pico-Teslas to nano-Teslas that are produced in muscles and nerves by the underlying ionic currents of cellular electrophysiology. The gadget highlights these bio-signals against instrumental and ambient noise using an integrated ultra-low-power microcontroller and an advanced AI-based signal processing platform. This pipeline has trained neural networks and implemented algorithms to do intelligent noise removal and feature extraction in order to convert raw quantum measurements into useful information. The ultimate goal is to enable new diagnostic applications. This involves ongoing monitoring of peripheral nerve health by tracking measurable changes in the nerve action potentials in order to identify neuropathy early. It can also be used to monitor subtle neuro-magnetic activity to create a clear baseline of health and detect the subtle, upstream functional impairments that occur before the clinical manifestation of neurodegenerative diseases such as Parkinson's and Alzheimer's. The invention has ushered in a new era of proactive and preventative medicine by successfully integrating a quantum sensor into a functional wearable, providing a previously unattainable window into how the body works.
