薄膜多电极探针在相互之间距离为1mm的八点上测量直流电位,手术期间被用来测量人脑深部区域的慢变化电位。电极被置于一个直径为2mm,长为33cm的圆柱形手术测试仪上,该测试仪与接近于实体的Freiburg设备一起使用。现已引入一些新的技术来解决遇到的问题:1)在曲面基片上利用软膜片达到使组成成份分层的目的;2)在接近于实体的设备内为了在薄膜传感器和铜线之间获得安全的结合面
The thin-film multi-electrode probe measures the DC potential at eight points at a distance of 1 mm from each other and is used to measure the slow change potential in the deep region of the human brain during surgery. The electrodes were placed on a cylindrical surgical tester measuring 2 mm in diameter and 33 cm in length, which was used with a near-real Freiburg device. Some new technologies have been introduced to solve the problems encountered: 1) the use of flexible membranes on curved substrates for the purpose of delaminating the constituents; 2) in the proximity of physical devices to thin film sensors and copper wires Get a safe combination between
