Strain gauge

A strain gauge for mounting on a surface to measure strain in the surface, the strain gauge comprising first and second mounting pads arranged for securing to respective first and second portions of the surface, the first and second mounting pads having respective first and second upstanding walls each arranged to extend away from the surface to a bridging portion extending between the first and second upstanding walls, the strain gauge having a strain sensing element secured to one of the first and second upstanding walls, wherein:

• the first and second upstanding walls each have a proximal end that is located proximate to the bridging portion and a distal end that is spaced from the bridging portion, and
• the first and second mounting pads respectively have first and second base portions, the first base portion connected to the distal end of the first upstanding wall and extending away from the distal end of the first upstanding wall in a first direction, the second base portion connected to the distal end of the second upstanding wall and extending away from the distal end of the second upstanding wall in a second direction that is opposite to the first direction.

• wherein the bridging portion extends between the first and second upstanding walls in a bridging direction, and the strain sensing element is configured for measuring strain in the surface when the surface deforms generally parallel to the bridging direction.
