Abstract
The wireless capacitive load cell features a two-component strain member has a spring body and force transduction plate, which deforms when a load is applied to the structure. During loading, the force transduction plate moves the cantilever spring body out of a position of rest, which results in an indenter, located within the force transduction plate, contacting a capacitive transducer. The capacitive transducer converts deformation of the strain member into an electrical signal which is correlated to a specific load value. The microelectromechanical system that accompanies the capacitive transducer processes and prepares the signal for wireless transmission. The microelectromechanical system has a capacitive transducer, signal conditioner, microcontroller unit, and telemetry system. Additional embodiments of the wireless load cell may include acceleration and temperature sensors embedded within the microelectromechanical system. The spring body features hard stops to prevent excessive deformation which can be harmful to the capacitive transducer.
