HIGH CONTACT DENSITY PLANAR ARRAY

摘要

A laminated multi-electrode biocompatible implant (8), comprising a first layer (30) of flexible, biocompatible dielectric material having a first, exposed surface. A second layer (20) of flexible biocompatible dielectric material, is adhered to the first layer. Further, a third layer (10) of flexible biocompatible dielectric material is adhered to the second layer (20). Additionally, a first conductive trace (18) is interposed between the first layer (30) and the second layer (20) and a second conductive trace (18) is interposed between said second layer (20) and said third layer (10). Finally, a first conductor, which breaches said first layer, conductively connects the first conductive trace to the exposed surface of the first layer, thereby forming a first electrode (44) and a second conductor (40), which breaches the first layer (30) and the second layer (20), conductively connects the second conductive trace (18) to the exposed surface of the first layer (30), thereby forming a second electrode (42).
