    Abstract: 본 발명은 평평한 형상의 전극판; 상기 전극판은, 다수개로 배치되되, 상기 전극판과 전극판 사이에 배치되는 절연성 와셔에 의해 서로 이격되고, 상기 전극판에 형성되는 결합공에 삽입되는 절연성 체결부재에 의해 체결되고, 상기 전극판에는 다수개의 통공이 형성되며, 상기 전극판의 양극은 티타늄(Ti) 기재에 백금(Pt)이 도금된 것인 전극구조에 관한 것으로, 물의 전기분해시, 통공에 의해 전극판에서 발생되는 수소기포 및 산소기포를 상기 전극판으로부터 쉽게 이탈시킬 수 있고, 전극판의 표면에 종래의 돌출부와 같은 부분이 없으므로, 전극판과 다른 전극판을 이격 배치하여 전극판조립체를 구성할 때 그 부피를 최소화시킬 수 있고, 장시간 사용시에도 전해액의 농도 유지가 가능하고, 불순물로 인한 전극 사이의 숏트현상을 감소시킬 수 있다.

    Abstract translation: 电极结构技术领域本发明涉及具有扁平形状的多个电极板的电极结构体。 电极板通过绝缘垫圈彼此间隔开,并且通过插入在电极板中形成的联接孔中的绝缘耦合构件联接在一起。 多个通孔形成在电极板中。 电极板的正极通过用铂(Pt)镀钛(Ti)基材而形成。 在水的电解过程中,可以通过通孔有效地从电极板产生氢气泡和氧气泡。 由于在电极板上没有典型的突起,当电极板彼此间隔开以形成电极板组件时,其体积可以最小化。 即使长时间使用,可以可靠地维持电解液的浓度,能够防止由于杂质导致的电极之间的短路。

    Abstract: Microelectrode assemblies and related methods are disclosed for bio-stimulating and/or bio-sensing a target tissue. The assemblies can include a two-side substrate, an array of microelectrodes, each of the microelectrodes including a nano-wire embedded within the substrate and extending from a proximal end to a distal end and through the substrate, each nano-wire having a diameter preferably less than 1 µm. The substrate can include portions made of nano-porous material(s) through which the microelectrodes pass. The substrate with the embedded nano-wires can effectively be fluid impermeable. The proximal ends of the nano-wires can be adapted to be connected to an electronic device and the distal ends are adapted to be disposed in a biological environment for bio- stimulating a target tissue and/or bio-sensing activities of the target tissue. Suitable alloys such as platinum, platinum-iridium, and/or other noble-metal-alloyed compositions can be used for the nano-wires.
