Latest Patents
Fred Wellstood holds a patent for a "Scanning SQUID microscope with improved spatial resolution." This invention features a scanning SQUID microscope designed to acquire spatially resolved images of the physical properties of an object. The microscope includes a SQUID sensor positioned perpendicular to the plane of the object under investigation, allowing for the detection of the tangential component of the magnetic field generated by the object. The scanning process involves a position signal from a position interpreting unit, along with relevant output signals from the SQUID sensor, which are processed to derive spatially resolved images. The specific orientation of the SQUID sensor enhances the area of the SQUID chip, facilitating the fabrication of modulation and feedback lines in the same technological process. Additionally, the design incorporates larger contact pads, which reduce contact resistance and simplify connections with bias and read-out wires.
