摘要	Soft actuators with good flexibility, high stability, and excellent controllability have attracted extensive attention. However, dual-modal smart self-perception actuator with contact and noncontact actuating mode remains a challenge. Notably, soft actuators with in situ self-sensing monitoring capabilities have gained increasing attention in smart flexible devices. This work reports a smart actuator composed of polydimethylsiloxane (PDMS)/magnetorheological elastomer (MRE)/Ag/ polyimide (PI) (PMAP), which can not only well respond to bending stimuli but also be actuated by electromagnetic dual-modal actuation. Benefiting from the nanowire–nanoflake coupling structure of conductive Ag layer, the PMAP film exhibits excellent electrical sensing and electro-heat generation behavior. The ΔR/R0 of PMAP film increases from 5.1% to 24.7% during the bending test. Moreover, the PMAP film realizes contact electrothermal actuation due to the mismatch of thermal expansion coefficient between PDMS matrix and PI tape. Under applying a 16 s of 2 V electrothermal actuation, the bending angle of PMAP film can increase from 31.1° to 219.3°. Moreover, MRE matrix endows the PMAP film with noncontact magnetic deformation characteristic. This multifunctional smart flexible device integrated with in situ sensing perception and contact and noncontact dual-modal actuation performances possess high potential in electronic devices and robots. © 2023 Wiley-VCH GmbH.
