EuQlid, Inc. recently secured a major technological breakthrough with the issuance of U.S. Patent No. 12724091. This patent, titled ‘Solid-state spin sensor with a compliant head’, introduces a powerful way to precisely measure magnetic fields. Scientists can now generate spatially resolved maps of magnetic fields with high resolution to inspect complex materials and devices.
Advanced Detection for Magnetic Fields
The innovation focuses on a compliantly coupled sensor head exhibiting translational and rotational compliance. This system uses a color center ensemble in a solid-state substrate for detecting magnetic fields. A specialized optical microscope works in conjunction with an optical driving system to facilitate viewing and spin polarization. A magnetic field generator ensures biasing of the ensemble for better sensitivity. Actuation is controlled by a system responsive to force data or image data for precise positioning of the color center ensemble focally and in contact with a sample. This setup allows for incredible accuracy during wide-field quantum sensing of irregular surfaces.
October 2026 Patent of the Month
Swanson Reed granted this technology the Patent of the Month award for the Maryland state for the month of October 2026. This distinction highlights the invention as a substantial contribution to quantum sensing and industrial metrology. Developed by inventors David Glenn, Cole Meisenhelder, Stephen DeVience, Connor Hart, and Aakash Ravi, the solid-state spin sensor stands out for its unique non-destructive mapping capabilities. The patent demonstrates a clear advancement for the semiconductor and energy storage sectors, aligning directly with the criteria of rigorous technological progress that Swanson Reed recognizes in the region.
Eligibility for R&D Tax Credits in the USA
The practical applications of this solid-state spin sensor present multiple avenues for companies to qualify for an R&D tax credit in the USA. Businesses that integrate this quantum sensing technology to develop new or improved semiconductor packaging, optimize backside power delivery systems, or evaluate battery degradation can claim these efforts as qualified research activities. The process of testing new operational parameters, experimenting with three-dimensional architecture validation, and overcoming technical uncertainties using the precise magnetic field mapping provided by the sensor directly aligns with the four-part test required by the Internal Revenue Service. Consequently, organizations investing in these experimental engineering integrations can effectively offset their development costs through federal and state R&D tax incentives.
