Technology & Products
Key Products
MicroWire passive magnetic sensors (temperature, pressure, magnetic field, electric current, torsion, vibration, position, flow, chemical MOF, identification, linear motion, shape memory, binary, wear & tear sensors); custom sensor prototyping and integration services; MicroWire-based sensing systems for smart electric motors, smart battery applications, self-monitored assembly, anti-counterfeit, and structural health monitoring.
Technological Advantage
Patented MicroWire technology combining glass-coated metallic microwires with proprietary sensing electronics; passive (no power needed at sensor tip); contactless readout from up to 10 cm distance through various materials; operates from -269°C to +500°C; immune to magnetic noise; embeddable without altering host material properties.
Differentiation
Value Proposition
Custom-developed, miniaturized (3-70 µm diameter) passive magnetic sensors based on MicroWire technology that enable contactless, unpowered real-time measurement of temperature, pressure, torsion, magnetic field, position, vibration, and electric current in extreme environments (-269°C to +500°C) where conventional sensors fail.
How They Differentiate
Unlike conventional sensors (thermocouples, strain gauges, optical sensors) that require power at the sensing point, wired connections, or line-of-sight, RVmagnetics' MicroWire sensors are fully passive, wireless, and can be embedded inside materials (composites, concrete, metal, human tissue) for contactless readout through solid barriers — enabling sensing in previously inaccessible locations with extreme temperature tolerance.
