磁感应是一种探测磁场并对其作出反应的能力，这种磁场使某些生物能够根据地球磁场进行定位，以达到导航目的。然而，事实证明，仅基于与地磁场的相互作用并可供人类使用的人工磁接收装置的开发具有挑战性。在这里，我们报告了一种顺应性和机械坚固的电子皮肤指南针系统，它允许人们相对于地球磁场进行定向。罗盘是在6亩厚的聚合物薄膜上制造的，并容纳了基于各向异性磁阻效应的磁场传感器。传感器的响应被定制为线性，并通过将传感器布置在惠斯通电桥配置中，实现了围绕地球磁场的最高灵敏度。我们的方法也可以用来为虚拟和增强现实应用程序创建交互设备，我们通过使用电子皮肤指南针在游戏引擎中对虚拟单元进行非接触控制来说明这一点的潜力。
Magnetoreception is the ability to detect and respond to magnetic fields that allows certain organisms to orientate themselves with respect to the Earth's magnetic field for navigation purposes. The development of an artificial magnetoreception, which is based solely on an interaction with geomagnetic fields and can be used by humans, has, however, proved challenging. Here we report a compliant and mechanically robust electronic-skin compass system that allows a person to orient with respect to Earth's magnetic field. The compass is fabricated on 6-mu m-thick polymeric foils and accommodates magnetic field sensors based on the anisotropic magnetoresistance effect. The response of the sensor is tailored to be linear and, by arranging the sensors in a Wheatstone bridge configuration, a maximum sensitivity around the Earth's magnetic field is achieved. Our approach can also be used to create interactive devices for virtual and augmented-reality applications, and we illustrate the potential of this by using our electronic-skin compass in the touchless control of virtual units in a game engine.
