title: A model of an electro-goniometer and its calibration for biomechanical applications.
abstract: The paper describes a detailed model of an electro-goniometer based on a elastic beam connecting two 'bases' whose relative orientation should be measured. This kind of device, which has been developed for the analysis of human motion, is also suitable for different applications even when one or more rotations around moving axes occur. After a theoretical analysis of the device working principles, experimental verifications of the model are presented. The paper analyses the characteristics of the device and shows how the goniometer outputs can be converted into more familiar angular conventions avoiding cross-talk and other artifacts.
