摘要
The present invention provides a range of motion measurement device using electroactive polymer (EAP) sensors to derive digital measurement angles. The EAP sensors may be attached to a stationary arm and rotating arm of the range of motion measurement device to detect a percentage stretched of the EAP sensors after measuring movement is performed. The percentage stretched of the EAP sensors based upon the law of cosines may be used with a transfer function in order to determine the range of motion angle of the joint.
