Description
導体107は、電極108を製作するために用いる方法と同じ種類の方法を使用して製造することができる。いくつかの実施形態では、導体107は、同一材料から作られ、電極108と同時に基板104上に配置される。いくつかの実施形態では、導体107が最初に積層され、電極108は導体107の一部上に積層される。例えば、導体107は、銀/塩化銀層が電極108に塗布される前に塗布されるシルクスクリーンのカーボンブラックでもよい。あるいは、導体107は、炭素又は銀/塩化銀層が電極108に塗布される前に塗布されるシルクスクリーンの銀でもよい。いくつかの実施形態では、導体107及び電極108は、シルクスクリーンプロセスを使用して製造する銀/塩化銀である。
(1)電極308ac/308bcはそれぞれ、左/右目の下の皮膚に配置され、電極308aa/308baはそれぞれ、左/右側のこめかみの近くに配置され、
(2)電圧差は、接触位置309ac/309bcと接触位置309aa/309ba間でそれぞれ測定され、
(3)両眼は正電位を生成する、
と仮定する。次いで、対300の鏡面対称により、電極アレイ301a及び電極アレイ301bによって測定される電圧差は、両方正である。
