Magnetic-Based Polydimethylsiloxane Microspheres for Magnetic Field Measurement [PDF]

IEEE Transactions on Instrumentation and Measurement, 2022
Magnetic-based polydimethylsiloxane microspheres (MPMs) are fabricated and its applications for measurement of magnetic field are investigated. The MPMs are prepared by first incorporating the uniformly sized Mn3O4 nanocrystals into polydimethylsiloxane (PDMS) matrix, and then using a self-assembling method to obtain a chain of microspheres on the ...
