N2 - Wearable and flexible magnetostrictive materials are required for the realization of devices related to the Internet of Things. Soft magnetostrictive materials are also expected to be used as tactile devices in telemedicine applications. This study reports on the successful fabrication of a material made up of Fe49Co49V2 alloy particles dispersed in a polyurethane (PU) matrix (PU–FeCoV); this material was used to make soft magnetic composite sheets with a positive magnetostriction effect. It was found that several PU–FeCoV soft composite sheets also showed a negative magnetostriction on one side of the composite sheets. This study revealed that the large pores induce this bending phenomenon in the PU–FeCoV soft composite sheet. The magnetic flux density of the PU–FeCoV soft composite sheets was found to vary with repeated loading. Hence, we believe that PU–FeCoV soft composite sheets may have potential applications as flexible sensing and vibration energy harvesting devices as well as in haptics devices.
