Abstract

Magnetoactive polymer composites (MAPCs) are materials composed of a polymer matrix embedded with magnetic particles that mechanically respond to external magnetic fields. MAPCs can be programmed to be adjusted remotely without physical interventions using a magnetic field to generate the desired re...
