A force sensor comprising a printed circuit strain gauge has the strain gauge pattern (42) formed on a dielectric layer (38) <u>in situ</u> on the surface of the structural support (16), the strain of which is to be measured. The strain gauge may be formed from a conductive layer by etching and further areas of the same or another conductive layer on the dielectric layer may be simultaneously treated to provide processing circuit elements for the strain gauge. The method of construction can simplify the manufacture of force sensors and also improve the quality of the sensors.
