(A) Large, bulky magnetic field generators necessary for the control of small soft robots comprised of MEs (Manamanchaiyaporn et al., 2020), (B) a rigid MRF valve, showing both traditional and jamming designs (Leps et al., 2020), (C) a magnetically-selected sME-based joule heater (Yun et al., 2019), and (D) an anisotropic hybrid sME with varying resistivity and piezoelectric properties based on the anisotropy angle of the magnetic particles (Yun et al., 2020).
