Description

technical field [0001] The invention relates to a measuring device for detecting the mechanical impedance of the human body, in particular to a novel measuring device for the mechanical impedance of the human body and a method for measuring the mechanical impedance of the human body in motion by constructing a virtual exercise environment by using the device. Background technique [0002] Human mechanical impedance is a set of parameters used to characterize the physiological characteristics of limbs from an engineering point of view. At present, domestic research on the physiological characteristics of limbs is limited to the fields of electrical impedance and myoelectricity, and there is no research on the mechanical impedance of the human body. Most of the foreign researches on the mechanical impedance of the human body are the research on the mechanical impedance of the human body in a static state, but it has always been difficult to measure the mechanical impedance of ...
