Abstract: A system for an acoustically driven ferromagnetic resonance (ADFMR) based sensor. The system may include a power source, that provides an electrical signal to power the system, at least one circuit comprising a set of ADFMR circuits, sensitive to external electromagnetic fields, a power splitter, a power combiner and a detector circuit. The system functions to detect and measure external electromagnetic (EM) fields by measuring a perturbation of the electrical signal through the ADFMR circuits due to the EM fields.

Abstract: Systems and method for a multi-array magnetic sensing component, which can include a circuit base platform; a set of magnetic sensors arranged on the circuit base platform; and a circuit system comprising intermediary circuit components, signal input, and a signal output, the signal input being an electrical oscillator signal input and being directable to each magnetic sensor in the set of magnetic sensors, the signal output including magnetic field measurements from the set of magnetic sensors, wherein each magnetic field measurement is individually selectable, the circuit system being configured to turn on or off subsets of the set of magnetic sensors, and the intermediary circuit components including a mixer.

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.
