Elastic magnetic sensor with isotropic sensitivity for in-flow detection of magnetic objects

Abstract

We present a conceptually new approach for the detection of magnetic objects flowing through a fluidic channel. We produce an elastic and stretchable magnetic sensor and wrap it around capillary tubing. Thus, the stray fields induced by the flowing magnetic objects can be detected virtually in all directions (isotropic sensitivity), which is unique for elastic sensors when compared to their rigid planar counterparts.
