The pressure sensitive sensor includes a sheet base, an application-side and a receiving-side electrode provided on the sheet base and conducting coatings provided on the electrodes. The conductive electrodes have pressure-sensitive conductive ink containing conductive carbon black. Resistance between the application-side electrode and the receiving-side electrode changes by a contact area between the conductive coatings on the electrodes. The pressure-sensitive conductive ink has an enhanced strength as a resin and an enhanced effect of dispersion of the conductive carbon black by adding 30 to 70 parts by weight of silicon dioxide to 100 parts by weight of silicone elastomer component as a binder. The pressure-sensitive sensor has output stability and linearity at temperatures in a wide range from &#x2212;40&#xb0; C. to 85&#xb0; C.

Pressure-sensitive sensor

An apparatus for personal identifying retrieves the personal identification number and entry conversion data corresponding to the identification number when a user is identified. The apparatus converts the numeric values entered from the numeric buttons, based on the entry conversion data. The apparatus collates the converted numeric values with the personal identification number.

A pressure-sensitive conductive ink composition includes a thermoplastic resin and a conductive filler. The thermoplastic resin is added with a curing agent capable of a partial crosslinkable reaction. The resulting composition maintains its pressure-sensitive characteristics, even at elevated temperatures.

Pressure-sensitive conductive ink composition

A polyurethane elastomer actuator comprising a polyurethane elastomer 1 capable of deforming due to the orientation by an electric field, wherein the shrinkage displacement occurring at the time of the application of an electric field is transformed into other displacement. This polyurethane elastomer actuator does not require electrolyte and high voltage. Since it is not accompanied by chemical reactions and heat generation, its durability hardly deteriorates. This actuator deforms largely during driving.
