∆R = Change in resistance of strain gauge
S
a
= Gauge factor of strain gauge
R
o
= Resistance of strain gauge unstrained
ε = Strain applied to strain gauge
The electronic hardware, described in Section 3.3, measures the change in resistance and the
software, described in Section 4, converts this change to force and torque components.
