A method is provided for producing a bioelectrode capable of reducing potential variation noise due to a polarization voltage. The method for producing the bioelectrode comprises forming an electrically conductive rubber body containing a silicone rubber and a silver powder, and immersing the electrically conductive rubber body in an inorganic salt-containing solution at 70&#xb0; C. or more and 180&#xb0; C. or less.

Method for producing bioelectrode

An object of the present invention is to provide a bioelectrode, which can stably measure biological information and is suitable for repeated use, and a method of manufacturing the bioelectrode. This object is solved by a bioelectrode comprising a silver coating layer provided on a conductive silicone rubber electrode, wherein the conductive silicone rubber electrode is composed of a silicone rubber containing conductive carbon particles, the silver coating layer is composed of silicone rubber and at least one of agglomerated silver powder and flake-like silver powder, and the silver coating layer has a thickness of 18 &#x3bc;m to 80 &#x3bc;m, and, preferably, in which the silver powder contains both the agglomerated silver powder and the flake-like silver powder.

Bioelectrode and method of manufacturing the bioelectrode

A bioelectrode includes a conductive rubber electrode and a silver coating layer provided on the conductive rubber electrode and containing a silicone rubber and silver particles. The silver coating layer contains a modified silicone and contains ions for ion conduction among the silver particles.

The present invention aims at providing a cover structure of a tactile sensor and a tactile sensor that can secure sufficient adhesion between a sensor body and a covering layer without providing an adhesive layer and have no possibility of causing a sensor to make detection error due to the covering layer formed thereon. A cover structure of a tactile sensor according to the present invention includes a sensor bodyand a covering layermade of elastic body molded on the sensor body. The covering layerincludes at least two layers of an outer layerdisposed as the outermost layer and an inner layerdisposed to come in contact with the sensor bodyand having a higher adhesiveness and a lower hardness than those of the outer layer, and is integrally molded with the sensor bodyby the cast molding. It is preferable that the sensor bodybe disposed on the top surface of the base, the covering layercover over the sensor bodyand the base, and the inner layerdo not cover the bottom surface of the base

A polymetaphenylene isophthalamide porous hollow fiber membrane is produced by extruding a film-forming solution comprising polymetaphenylene isophthalamide, polyvinylpyrrolidone and an inorganic salt through a concentric double annular spinning nozzle while keeping the film-forming solution at 70&#xb0; C. or higher, thereby conducting dry-and-wet spinning, followed by moisture retention treatment, where it is preferable to subject the resulting porous hollow fiber membrane obtained by dry-and-wet spinning to heat treatment in water at 80&#xb0; C. or higher before the moisture retention treatment. The polymetaphenylene isophthalamide porous hollow fiber membrane resulting from wet heat treatment under wet heat conditions at the temperature of 100&#xb0; C. and the humidity of 8% for 1,000 hours or more has a strength at break of 10 MPa or more and a elongation at break of 80% or more, where the elongation at break can keep at least 80% as high as that before the wet heat treatment, and also has distinguished resistance to moisture and heat and humidifying performance, so that the membrane can be used as an effective humidifying membrane for polymer electrolyte fuel cells, etc.
