[[Strain gauge|Strain gauges]] [[Deformation (engineering)|deforms]] when torque is applied. This results in changes in [[Electrical resistance and conductance|electrical resistance]] proportional to the torque, allowing to measure the strains. These sensors provide high accuracy, and their reliability and simple integration results in their wide usage.<ref name=":0" />

=== Piezoelectric effects ===

[[File:SchemaPiezo.gif|thumb|Animated schema of the piezoelectric effect]]

By using [[Piezoelectricity|piezoelectric crystals]], these sensors create an [[electric charge]], when mechanical stress is applied, thus capturing high-[[frequency]] dynamic torque events.<ref name=":3" />
