Abstract
It is possible to detect the compressive force being applied by means of the conventional compressive force detecting sensor. However, the time length and the magnitude of the compressive force fail to be detected and it is impossible to know the extent of damage as a result of the compressive force being applied. For solution of this problem, the compressive force detecting sensor of the invention includes a tape switch composed of a pair of belt-like electrode plates arranged in facing relation to each other with a predetermined spacing therebetween, said tape switch being covered with a pliable covering member therearound; a piezoelectric sensor having a cable or a film like shape laminated on said tape switch; and an outer shell of pliable material to cover said tape switch and said piezoelectric sensor.
