Abstract

A force sensor, flexible sensing element, and method for the force sensor are disclosed. The force sensor uses a flexible sense element with two flexible arms dedicated to measuring strain related to a pitch force and two flexible arms dedicated to measuring strain related to roll force. The use of two channels for each measurement provides a command lane and a monitor lane for strain measurements. Strain gauges are disposed on both the top and the bottom surfaces of each arm, thus providing two completely redundant systems. When a failure is detected in one of the systems, the redundant system can be implemented.
