work reports a novel triple-functional electronic skin (e-skin)
which shows both wonderful thermal–magnetic–mechanical
sensing performance and interesting magnetic actuation behavior. The
flexible e-skin comprises thermo-sensitive, magnetic, and conductive
tri-components, and their sensitive characteristics under 5–70
°C, 0–1200 mT, and 0.1–5.1 MΩ are studied,
respectively. Owing to the unique piezoresistive characteristic and
magnetorheological effect, the e-skin exhibits a rapid response time
(38 ms) to the external stimuli. The assembled e-skin with the triple-layer
structure can act as a functional sensor to monitor various human
motions, magnetic fields, and environmental temperatures. Based on
this e-skin, an intelligent magneto-active gripper is further developed,
and it can be used to grasp and transport targets by the actuated
force of magnetic field under various working conditions. Importantly,
the multi-functional sensing capability endows the gripper with real-time
deformation and ambient temperature perception characteristics. As
a result, because of the ideal multi-field coupling sensing and magnetic
active features, this e-skin shows a wide prospect in wearable electronics,
man–machine interactions, and intelligent transport systems.
