Abstract: A system and method for a wearable field sensing device for biological electromagnetic (EM) field measurement including: a wearable structure; a biological sensor array, on or within the wearable structure, such that each biological sensor is situated adjacent to the body of the user, and wherein each biological sensor includes at least one ferromagnetic resonance (FMR) sensor; a power system, providing the power for the system; and control circuitry, electrically coupled to the system. The FMR sensor comprises an acoustically driven ferromagnetic resonance (ADFMR) sensor. The system may additionally include sensor shielding and an ambient sensor array to detect a block external fields.

Abstract: A system and method for design and operation an acoustically driven ferromagnetic resonance (ADFMR) based sensor for measuring electromagnetic fields that includes: a power source providing an electrical signal to an ADFMR circuit, sensitive to electromagnetic fields, wherein the ADFMR circuit comprises an ADFMR device. The system detect and measure external electromagnetic (EM) fields by measuring a perturbation of the electrical signal through the ADFMR circuit due to the EM fields. The system and method may function to facilitate the design and operation of a chip-scale ADFMR device usable to measure EM fields.
