Project introduction:
A technology company in Slovakia has developed the world's small passive sensor based on MicroWire technology. The founder of the company is a European professor of microfilament technology and condensed matter magnetism, and has 25 years of research experience in basic magnetism and applied magnetism. He developed a passive non-contact sensing technology based on glass-coated magnetic microfilament.
Production technology of glass coated microfilament
Glass-coated microfilament is a kind of composite material, which is composed of metal core covered by glass shield. They are prepared by drawing and rapid quenching of molten alloy and glass. They have characteristics in magnetization process and mechanical properties. This makes them suitable components for sensing various physical quantities in engineering applications.
Magnetism is mainly determined by the magnetoelastic interaction between the magnetic moment and the mechanical stress distribution produced in the production process. Axial mechanical stress is caused by stretching and rapid quenching of wire rod. Radial stress and circumferential stress are caused by the different thermal expansion coefficients of glass coating and metal core. In addition, the shape anisotropy also depends on the physical size (wire diameter 1-40μ m, length 1-4cm).
Non-contact glass-coated microfilament sensor
The micro-wire sensor developed by the company is a miniaturized (about 3-70 m in diameter) non-contact magnetic sensor, which is used to measure physical quantities (temperature, pressure, tension, mechanical stress, torsion, magnetic field, position, etc.). The micro-conductor is composed of a metal alloy core (about 1-50 m in diameter) and a glass coating (2-20 m in thickness).
Microfilament sensors help overcome the sensing obstacles in materials, parts and processes, including IIoT, Industry 4.0, composite materials, motors, battery cells and additive manufacturing, thus realizing continuous structural health monitoring (SHM), nondestructive testing (NDT) and predictive maintenance. The system can also be used to identify and monitor the wear state.
They are small in size, high in added value, durable, simple in production process, and have symmetry, glass coating and the possibility of non-contact sensing, so they can be widely used as micro sensors in different industries: Internet of Things, Industry 4.0, structural health monitoring, automobiles, aerospace, intelligent materials, medical care, anti-counterfeiting fields and so on. Accurate measurement can be carried out in a non-contact environment. Provide data such as mechanical strain (including bending, torsion and compression), temperature, magnetic field, position/displacement, vibration and wear state.
