Inductive sensing of magnetic microrobots under actuation by rotating magnetic fields

PNAS Nexus, 2023
Abstract The engineering space for magnetically manipulated biomedical microrobots is rapidly expanding. This includes synthetic, bioinspired, and biohybrid designs, some of which may eventually assume clinical roles aiding drug delivery or performing other therapeutic functions. Actuating these microrobots with rotating magnetic fields (

A Flexible Magnetic Field Sensor Based on AgNWs & MNs-PDMS

Nanoscale Research Letters, 2019
This paper presents a new flexible magnetic field sensor based on Ag nanowires and magnetic nanoparticles doped in polydimethylsiloxane (AgNWs & MNs-PDMS) with sandwich structure. The MNs act as the sensitive unit for magnetic field sensing in this work.
