可指方向的手表数字手表不久将可同时用作指方向，即使多云天气也罢。英国不莱毛斯西南理工学院的研究人员已研制出一种电子传感器，可检测到地磁埸的强度和方向。现在正进一步进行微形化，以便最后可装配在１ｃｍ见方的芯片上，装进手表内。该传感器使用一种磁阻材料，即... Watches that can point in the direction Digital watches will soon be used simultaneously as a direction, even in cloudy weather. Researchers at Southwestern Polytechnic Institute in Notre Dame, UK, have developed an electronic sensor that detects the strength and direction of geomagnetic 埸. Now further micro-shaped, so that the final can be assembled in 1cm square chip, into the watch. The sensor uses a magnetoresistive material, namely ...
