Hybrid Piezoelectric–Magnetic Self‐Sensing Actuator using Novel Dual‐Alignment Magnetic/Mechanical Processing for Vibration Control of Whole‐Body Vibrations

Multi-stimuli-responsive/-functional polymeric materials can respond to numerous stimuli and execute multiple tasks, overcoming barriers faced by single-stimuli materials. Herein, the development of hybrid piezoelectric–magnetic self-sensing actuator (HPMSA) that both sense actuate is proposed. This iron oxide/functionalized carbon nanotube/polyvinylidene fluoride film optimizes piezoelectric magnetic properties through dual-alignment fabrication, utilizing strong element bonds for simultaneous alignment. Magnetic nanoparticles are advantageous over nanorods due latter's randomized shape anisotropy decreasing magnetization. The dual mechanical processing increases polar β-crystal content 88%, where alignment alone degree crystallinity 66%. As a vibration damper, HPMSA operates within 40–600 Hz frequency, with sensing sensitivity 2.5 mV g−1 0.72 m s−2 weighted acceleration damping, lowering passenger health risks.
