Abstract
According to some embodiments, a load cell for determining a weight of a large object comprises a base plate comprising at least one recessed opening, a bulk metallic glass plug disposed in the at least one recessed opening of the base plate, and a top plate positioned above the base plate. A portion of the top plate is supported by the bulk metallic glass plug. The load cell further comprises a micro strain sensor coupled to the bulk metallic glass plug. The micro strain sensor is operable to determine a change in micro strain on the bulk metallic glass plug. The bulk metallic glass plug extends to a height where the top plate does not contact the base plate.
