  • Patent number: 9314183
    Abstract: A transducer assembly including a support terminal and at least one probe extending from the support terminal is adapted to enable a transducer to penetrate and slide through patches of hair covering a subject area of a person. The probe includes at least one leg structure supporting a transducer disposed at the distal end of the leg structure for sensing or stimulating the state of a particular property of a selected subject area when the transducer is applied by the leg structure to the selected subject area. The leg structure is so disposed in relation to the support terminal as to be disposed at a non-perpendicular angle to the subject area when the transducer assembly is applied to the selected subject area. The leg structure is adapted to flex when the transducer is applied under pressure to the selected subject area to thereby cause the transducer to slide on the subject area.

  • Patent number: 9272130
    Abstract: Provided are a living body stimulating electrode, a living body stimulating electrode apparatus, and a method for producing a living body stimulating electrode. The living body stimulating electrode has a flexible circuit board (FPC) between a living body stimulating electrode and a resin part. The resin part and the FPC are fixed with the living body stimulating electrode. Specifically, the flexible circuit board is disposed between the living body stimulating electrode and the resin part, and one or both of a stimulating electrode and a contact electrode constituting the living body stimulating electrode have an engaging part having a pressing part and a fixing part. The pressing part presses the flexible circuit board onto the resin part. Simultaneously, the fixing part is penetrated through a through hole formed in the flexible circuit board and pressed into a hole formed in the resin part, thereby fixed to and held by the resin part.
