  • Publication number: 20210316305
    Abstract: A microfluidic chip includes an upper surface, a lower surface opposite the upper surface, a flow passage for fluid located between the upper surface and the lower surface, a communication hole that communicate with the flow passage and open at the upper surface or the lower surface, and an annular seal formed from an elastomer, the annular seal being placed in contact with or being formed on the upper surface or the lower surface at which the communication hole opens and surrounding the communication hole. The microfluidic chip further includes a support structure fixed at a position within the flow passage, the position overlapping the annular seal, the support structure securing a height of the flow passage so as to prevent blockage of the flow passage.

  • Publication number: 20210000371
    Abstract: A bioelectrode and a method for producing the bioelectrode are provided. The bioelectrode has a non-complicated structure, satisfactory elasticity, and is capable of preventing an increase of contact impedance due to an increase of the number of times of usage. The bioelectrode includes a support member, which is an electrically conductive member, and at least one electrode member, which is a member projecting from the support member. At least the electrode member is molded from an electrically conductive rubber containing a silicone rubber and treated metal particles containing a crosslinkable functional group on a surface thereof.

  • Publication number: 20200268267
    Abstract: A bioelectrode includes a support member and at least one electrode member. The support member is a conductive member, and the electrode member is a member projecting from the support member. The at least one electrode member is molded from a conductive rubber containing a silicone rubber and metal particles, and the electrode member has an exposed face, which is a face formed by removal of a molded surface layer at a tip end.
