With a total of 2 patents, his work reflects a commitment to innovation and precision.
Latest Patents
One of Stefano's latest patents is a torque magnetometer utilizing integrated piezoresistive levers. This device is designed to measure the magnetization of very small anisotropic samples. The sample holding platform is cantilevered from the substrate by parallel legs, on which piezoresistors have been applied. A Wheatstone bridge, which includes the piezoresistors, is fully integrated on a magnetometer substrate. Specific output connections are made to the electrical conductors of the bridge in a manner that eliminates Hall effect error signals in an alternative embodiment.
Another significant patent is for an apparatus and method for regulating temperature in a cryogenic test. This dual capillary inlet cryogenic test chamber can continuously regulate temperature between about 1.5 K and 400 K. A controllably heated capillary tube is located in the cryogenic reservoir, spaced from the test chamber and thermally insulated from the cryogen. This setup allows for stable operation at any temperature within its range, or to smoothly sweep through any predetermined temperature range.
