About
Yoshimi Hatsukade is a leading figure in the development of high-temperature superconducting (HTS) SQUID-based non-destructive evaluation (NDE) systems. His research focuses on creating robust, mobile NDE platforms that can operate in unshielded, real-world environments. A key contribution is the integration of HTS-SQUID gradiometers and magnetometers onto robotic arms, enabling three-dimensional scanning of fixed structures. His work on ramp-edge Josephson junctions and bicrystal substrates has been instrumental in improving sensor robustness. Notably, his 2011 paper on an HTS-SQUID gradiometer with ramp-edge junctions has garnered 16 citations, while his 2008 and 2009 papers on robot-based mobile systems each have 10 citations. Hatsukade has demonstrated the detection of deep-lying defects in aluminum alloys using eddy current techniques with a moving SQUID, a significant step for industrial applications. His development of active magnetic shielding using fluxgate sensors has been crucial for maintaining performance in noisy environments. Through these innovations, Hatsukade has advanced the practical deployment of SQUID sensors for structural health monitoring, bridging the gap between laboratory sensitivity and field-ready inspection tools.
