Patent ID: 7174790

Claim:
An object detecting device for preventing a seizure of an object between an opening and an opening-closing unit for opening and closing said opening, an end of said opening-closing unit being arranged to contact an edge of said opening, said object detecting device comprising: a pressure-sensitive sensor disposed at one of said opening and said opening-closing unit, said pressure-sensitive sensor comprising: pressure-sensitive means for generating an output signal depending on deformation; and support means for supporting said pressure-sensitive means at said one of said opening and said opening-closing unit, said support means being capable of being bent along a shape of one of said end of said opening-closing unit and said edge of said opening; and judging means for judging the contact of the object with said pressure-sensitive sensor on the basis of an output signal of said pressure-sensitive sensor, wherein said pressure-sensitive means has a co-axial structure including: a central electrode; a piezoelectric layer around said central electrode; and an outside electrode around said piezoelectric layer; and wherein said outside electrode includes: a polyethylene terephthalate layer; and an aluminum film on said polyethylene terephthalate layer.
