A number of instruments have been reported in the literature
that is specifically designed to measure skin friction.
These devices can be grouped into two classes; in the first
group, a probe slides over the skin, while in the second
group a probe is rotated against the skin. Such deviceshave been designed to measure the efficacy of cosmetic treatments.
In this paper, we report on the manufacture and use in
exploratory experiments of a new test system that is designed
to evaluate the frictional component of the feel of fabrics. The
new design enables the friction between the finger tip and a
material to be determined in real time at speeds and normal
loads that are typically used by individuals in their sensory
evaluation of materials. The aim of the development has been
to provide a lowcost but reliable instrument that can be easily
used to produce dependable data.

2. Design of the friction test rig
The basis of the system is the use of strain gauged flexure
element technology. Fig. 1 is a schematic diagram of the test
system.
The 150mm square sample table forms the top part of
the X-axis flexure couple. The lower planar element in the
X-flexure couple also forms the lower element of the Y-axis
flexure couple that flexes in the perpendicular direction. The
second planar element of the Y-axis couple passes between
the planar elements for the X-flexure couple.
For both the X- and the Y-flexure couples, displacement
between the two planar elements is resisted by the spring force
of the flexure elements, and is measured by the strain gauges
bonded to the flexure elements. The strain gauges on the fourflexure elements are formed into a Wheatstone bridge. The
output from this bridge forms a signal proportional to the
frictional force in the relevant direction.
Measurement of the vertical force is made by using three
strain-gauged flexure couples. These are arranged with two
on one side of the X- and Y-flexure couples, and one on the
other side to give a triangular configuration. Again, each of
these flexure couples has four strain gauges arranged in a
Wheatstone bridge configuration, and the signal from these
gives a measure of the vertical force at that sensor. The sum
of the three vertical forces equals the total normal force, and
the partitioning of forces between the three sensors is used
to calculate the position of the application of force on the
sample table.
