Determination
of Mechanical Properties of Soft Tissues Using PHANTOMTM
Device
The PHANTOMTM
is a
haptic device which is can be programmed to produce a predefined
force. In this project the PHANTOMTM
was programmed to produce a force
that is gradually increased over a period of time. This force is
applied on various material and the the corresponding deformation in
the material is measured. This information is then used to calculate
the mechanical properties of the material.
Highlights of the work:
In indentation test some areas get compressed
and some areas get shared. Fresh goat tissue specimen was taken of
irregular shape. As per measured co-ordinates Pro\E model prepared.
Then quasi-static test carried out with help of haptic device. Same
time simulation also run on ANSYS & found good agreement with
experimental results. Young modulus comes out to be 4.8KPa which
close approximation.
