Abstract
An impulse sensor having: a long elastic structure formed of a material to be deformed according to an impulse; a cable insertion hole formed in the elastic structure; and a cable inserted through the cable insertion hole, the cable being operable to cause a variation in propagation energy due to its deformation. A distance from a central line of the cable to an outer surface of the elastic structure is varied in a longitudinal direction of the elastic structure.
