US Patent Issued to Washington University on Aug. 12 for "Multi-modal sensing blockchains using Fowler-Nordheim sensor data logger" (Missouri Inventor)

ALEXANDRIA, Va., Aug. 12 -- United States Patent no. 12,386,917, issued on Aug. 12, was assigned to Washington University (St. Louis).

"Multi-modal sensing blockchains using Fowler-Nordheim sensor data logger" was invented by Shantanu Chakrabartty (St. Louis).

According to the abstract* released by the U.S. Patent & Trademark Office: "A sensor blockchain system is provided. The sensor blockchain system includes a plurality of sensor-data-loggers, wherein each sensor-data-logger includes a memory device which utilizes FN tunneling. An input to the sensing interface alters the geometry of the energy barrier to change the electron leakage rate and the current state of the sensor-data logger is determined by an initial state of the sensor-dat...
