The application for the patent was published on April 17, under issue no. 16/2026.
According to the abstract released by the Intellectual Property India: "The present invention relates to a Superconducting Quantum Interference Device (SQUID) designed for the precise measurement of extremely weak magnetic fields with enhanced sensitivity, stability, and efficiency. The system operates based on the principles of superconductivity and quantum interference, utilizing a superconducting loop integrated with optimized Josephson junctions. These junctions enable the detection of minute variations in magnetic flux, ensuring high accuracy and reliability in measurements. The invention further incorporates advanced superconducting materials capable of operating at relatively higher temperatures, thereby reducing dependence on complex and costly cryogenic cooling systems. The proposed device includes a comprehensive noise reduction framework to minimize environmental interference. This framework consists of multi-layer electromagnetic shielding, vibration isolation mechanisms, and adaptive filtering techniques, which collectively improve the signal-to-noise ratio. A low-noise amplification stage is integrated to enhance weak signals without distortion, ensuring accurate signal representation. Additionally, a flux-locked loop (FLL) feedback mechanism is employed to maintain linearity and stability by continuously compensating for variations in magnetic flux. The invention also integrates a real-time data acquisition and intelligent signal processing module. This module enables rapid analysis, visualization, and interpretation of magnetic field data using advanced electronic components and computational techniques. The intelligent processing capability enhances measurement precision and supports efficient data handling. Furthermore, the system is designed to be compact, portable, and modular, allowing easy deployment in both laboratory and field environments. Its scalable architecture supports multi-channel measurements, making it suitable for applications such as medical diagnostics, geophysical exploration, scientific research, and non-destructive testing. Overall, the proposed SQUID system provides a cost-effective, reliable, and high-performance solution for ultra-sensitive magnetic field measurement, contributing to the advancement of modern quantum sensing technologies."
