G01L 1/18 using properties of piezo-resistive materials, i.e. materials of which the ohmic resistance varies according to changes in magnitude or direction of force applied to the material
Introduced: September 1968
Full Title
Full titles differ between systems:
IPC:
Measuring force or stress, in general > using properties of piezo-resistive materials, i.e. materials of which the ohmic resistance varies according to changes in magnitude or direction of force applied to the material
CPC:
Measuring force or stress, in general (measuring force due to impact G01L5/00) > using properties of piezo-resistive materials, i.e. materials of which the ohmic resistance varies according to changes in magnitude or direction of force applied to the material
