Measuring System of Power Output of Wheelchair Locomotion

Abstract

This system can contimously measure the power output of wheelchair locomotion.It consists of special handrim, wheeI, wheel rotation detector, micro strain amplifier and micro data recoder.Locomotion torque is detected by 4 strain-gages that are installed between a special handrim and wheel.The voltage of locomotion torque and wheel rotation pulse are detected and recorded to a micro-data recorder.After the data has been collected, the measurements are used to calculate the running speed, distance, torque and power output.This system will fit easily onto various types of wheelchairs.
