A Sensor Used to Detect the Thigh Human-Machine Coupling Force in Lower Limb Rehabilitation Robot

Abstract:

The acquisition of the patients’ active force is the key process to realize the active rehabilitation function of lower limb rehabilitation robot. This paper analyzes the relationship of human-machine coupling force and patients’ active force, based on what put forward a proposal to acquire the active force .A sensor is designed to detect the human-machine coupling force and a stress analysis is carried on based on the actual usage of the sensor. The scheme of the stress foil arrangement and bridge circuit design are discussed in the paper. And a FEA is also carried out to analyze the strain situation of the elastomer.
