  • Publication number: 20200367795
    Abstract: A wearable device and method for noninvasive and continuous monitoring of blood glucose level in a patient. The device may include a unilateral permanent magnet generating a static magnetic field to a target area under the skin of the patient, the target area comprising blood vessels and tissue surrounding the blood vessels. The device may also include a transmitter delivering a radiofrequency (RF) field to the target area to excite proton nuclear spins in the target area, wherein at least a portion of the transmitter is positioned between the magnet and the skin. The device may further include a sensor detecting a RF signal from the excited proton nuclear spins in the target area. A processing arrangement may receive data corresponding to the detected RF signal from the sensor and determine a level of blood glucose in the patient based on the data.
