A distinctive feature of cast microwires with an amorphous structure of special alloys is their magnetic bistability. The magnetization reversal of such microwires is carried out in one jump (the Barhauzen effect). The critical length of the microwire segments on which the bistability effect is preserved is 5 mm and is 10-20 times smaller than for bistable bands and wires obtained by other methods, and the rate of magnetization reversal of bistable microwires is several times greater than that of analogues. Core material Fe-based alloys Insulation Glass and others. d is the diameter of the core from less than 1 μm to tens of μm D - outer diameter D / d(0.7 ÷ 1.7) + 10 / d Resistance 5 - 500 kΩ / Ohm Start field 1 - 200 A / m Magnetization reversal time 10 - 15 us Coefficient of squareness≤ 5 % Critical length≥ 5 мм Bistable microwires are intended for use in code markers for encoding goods (RFID), documents, securities, coding and remote control of actuators, sensor sensors, converters of electrical and non-electrical quantities; pulse transformers, chokes, delay lines.
We develop micro-winding technologies for ultra-small coils with ≤10 μm wires with magnetic /non-magnetic cores / coreless with diameter of ≥ 75 μm; Various shapes, geometries (1D, 2D, 3D, flat, coreless, helical, etc.); Measuring the external environmental parameters in harsh conditions, such as high humidity, low/high temperatures, pressure or even radiation; Capabilities for batch and high – quantity production. We can adjust the technology upon the requirements of the customer. Technological possibilities: - The minimum wire diameter is 5 μm (various insulations: Polyimide, Glass, PTFE (teflon), Polyvinylbutyral, etc. - Possibly integration of cores for various magnetic improvements - Coreless microcoils with various shapes - We provide the possibility to plant the coils on transistor pinouts for further integration into electronic circuits - There's the possibility to solder to the coils on PCB's for further integration into electronic circuits (RoHS and REACH compliant) - Other possibilities are placing the microcoils on various shaped potcores. Further fine tuning is possible for high frequency applications. - Quantity range - from 1 piece to millions of pieces!

What is a nanowire? Nanowires are small-diameter wires for manufacturing windings of electric micromachines, measuring coils and control devices. Nanowires are obtained from various metals and alloys: conductive, resistive, magnetic, semiconductor, with their simultaneous coating by glass insulation, with a diameter of less than 1 μm, including precious materials (Au, Pt, Ag, etc.). The use of nanowires - non-electric measuring transducers (temperature, pressure, speed, force, mass, etc.); - inductive converters; - transformers, motor windings; - complexes of filamentous nanostructures; - electrodes. DIAMETER OF MICROWIRES LESS THAN 1 micro m
