  • Secco E.L. - viscoelastic coefficient for finger - report

    Biomch-L members

    About my question on viscoelastic coefficient for human finger joints
    and a dynamic model of it:

    > I'm a phd student at Univ. of Pavia - Italy
    > I'm working to simulate the natural movement of an artificial human
    > finger.
    >
    > The question: preparing the dynamic model I am not be able to find
    > indicative values of the viscoelastic coefficient of the cartilagineus

    > finger joints (MP, PIP and DIP)
    > Is there any study on this? And on the inertia, weight and other
    dynamic
    > parameters of phalanges?
    >

    I've received these two answers and references:

    If I'm not mistaken, all of these studies employed either static or
    dynamic
    modeling.

    to live always the real intensely, without negating or forgetting
