Recent progress in branch of flexible electronics led to the expansion of its applications in artificial intelligence, the Internet of Things (IoTs), wearable electronics, etc. Flexible magnetic field sensors enable new generation of devices based on touchless interaction [1, 2]. However, integration of highly-sensitive magnetic sensors into non-planar surfaces still remains challenging. Although transfer printing method has been adopted to diversify the applicable substrates, the selection freedom is still limited. We propose a green transfer printing method, capitalizing on the following features: 1) our technique only relies on biocompatible water and does not resort to any additional treatments; 2) sensors can be transferred onto arbitrary substrates without performance degradation; 3) the transferred sensors have robust mechanical stability. Thanks to the above advantages, the magnetic sensors demonstrate promising potentials in on-skin electronics as human-machine interfaces, smart agriculture and household IoTs applications.
