Abstract
A weight sensor assembly including a strain gauge load cell is disclosed. The weight sensor assembly may be used in a smart cap. The weight sensor includes a platform for weighing objects and a load cell. The load cell includes an annular portion, and first and second beams coupled to the platform. Each of the beams includes a first end fixed to the annular portion and a second end that deforms as the platform displaces downward in response to an applied force. One or more strain gauges are mounted on the beams.
