摘要： A tire wear measurement device detects a magnetic field of a magnetic body embedded in a tread portion of a tire and measures the degree of wear of the tire from a change in the magnetic field. The tire wear measurement device includes a first magnetic field detection portion placed at a position at which the magnetic field of the magnetic body can be detected, and a second magnetic field detection portion disposed at a position at which the intensity of the magnetic field of the magnetic body differs from the intensity at the position at which the first magnetic field detection portion is disposed.

摘要： A polymer particle containing magnetic material includes a core and a polymer layer. The core includes magnetic fine particles. The polymer layer is located outside the core and surrounds the core. A shape ratio (Ric) is defined in each of the magnetic fine particles by dividing a diameter (Di) of an inscribed circle of the magnetic fine particle by a diameter (Do) of a circumscribed circle of the magnetic fine particle. The shape ratio (Ric) of the magnetic fine particle is 0.50 or more and 0.94 or less. The diameter (Di) of the magnetic fine particle is 5 nm or more. The diameter (Di) and the shape ratio (Ric) of the magnetic fine particle satisfy a relation formula of Di≤9.28×e{circumflex over ( )}(1.17×Ric).

摘要： Methods and apparatuses of identifying a type of material or material combination in a measurement location by Magnetic Induction Tomography (MIT) is disclosed. The methods can comprise providing a primary magnetic field primarily in a first direction into the measurement location; measuring an orthogonal component of a secondary magnetic field; classifying the orthogonal component of the secondary magnetic field with reference to a material or material combination type and thereby identifying a type of material or material combination in the measurement location. The orthogonal component of the secondary magnetic field is in a direction substantially orthogonal to the first direction.

摘要： A system and method for monitoring a characteristic of a material by measuring electrical or magnetic properties of the material. The system includes a material monitoring device having at least one electrode and at least one magnetic coil, and is in communication with a machine learning model trained to recognize characteristics of the material based on electrical and magnetic properties of the material. The material can be stimulated with an electrical stimulus or stimulating magnetic field, and an electrical response signal or magnetic response signal can be measured. Applications to monitoring water quality, beverages, foodstuffs, and other characteristics of materials is discussed.

摘要： Disclosed herein is a detection device comprising sensors with spin torque oscillators (STOs), at least one fluidic channel configured to receive molecules to be detected, and detection circuitry coupled to the sensors. At least some of the molecules to be detected are labeled by magnetic nanoparticles (MNPs). The presence of one or more MNPs in the vicinity of a STO subjected to a bias current changes the oscillation frequency of the STO. The sensors are encapsulated by a material, such as an insulator, separating the sensors from the at least one fluidic channel. A surface of the material provides binding sites for the molecules to be detected. The detection circuitry is configured to detect changes in the oscillation frequencies of the sensors in response to presence or absence of one or more MNPs coupled to one or more binding sites associated with the sensors.

摘要： The present invention relates to a magnetometric device that measures the magnetic properties of a sample and whose most notable characteristic lies in that it is portable and highly precise, and can be used for the detection of a magnetic signal from nanostructures exposed to a fixed external magnetic field of excitation, of a unique value, it not being possible to alter the external magnetic field. The fixed external field can only be altered by modifying the device by means of exchanging the permanent magnets; however, once the device is sealed, this field does not vary. Different quantities of the same magnetic material may be placed in the sample holder, increasing the measurement signal; the present device can therefore determine the magnetic mass being measured following calibration of the magnetic material employed.
