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.
