Latest Patents

One of her latest innovations is the oscillator-based solid-state spin sensor. This sensor is designed to be high-performance, low-volume, low-weight, and low-power. It operates based on a self-sustaining oscillator that can sense various fields, with a demonstration in magnetic sensing. The oscillator utilizes a dielectric resonator containing paramagnetic defects, connected to a sustaining amplifier in a feedback loop. The resonance frequency of the dielectric resonator shifts in response to changes in the magnetic field, allowing for precise measurements. The sensor consumes less than 300 mW of power and exhibits a sensitivity at or below tens of pT/√Hz, with a volume of less than 1 mL in some implementations.

Another notable patent is the ferrimagnetic oscillator magnetometer. Unlike traditional methods that use lasers, this magnetometer shifts the resonance of entangled electronic spins in a ferrimagnetic crystal when an external magnetic field is applied. The resulting microwave sidebands can be processed to yield magnetic field measurements with exceptional sensitivity, potentially reaching the spin projection limit of 1 attotesla/√Hz. This innovative approach relaxes stringent requirements on digitizers, making it a significant advancement in the field.
