Abstract Flexible spintronic sensors provide contactless, vector-resolved readout for wearables, implantable bioelectronics, and microrobotics, yet strain-induced inverse magnetostriction disrupts anisotropy and compromises stability. Magnetoelasticity originates from spin–orbit coupling, orbital hybridization, and exchange interaction in ferromagnets, further intensified by nanoscale thin-films. Strain-decoupled strategies—low-magnetostriction alloys and stress-relaxation architectures—stabilize domain states and preserve sensitivity. Looking forward, multiscale predictive frameworks bridging electronic structure, micromagnetics, and finite-element mechanics offer robust design of strain-resilient, conformable devices.
