Flexible Spintronic Neuromorphic Devices for Sensing Signal Processing

Integrating spintronic devices onto flexible substrates has been demonstrated to offer new opportunities for flexible electronics. For instance, spintronics-based electronic skins enable humans to perceive and interact with magnetic fields. Beyond their advantages of low power consumption and high endurance, spintronic devices possess intrinsic brain-like computing capabilities, which, however, remains underexplored in flexible electronics. Here, we develope a spintronic neuromorphic device with inherent thermally activated relaxation and nonlinear spin-orbit torque switching behaviors, realizing the nonlinear response and fading memory requirements for reservoir computing. The device demonstrates powerful capabilities in accurately recognizing sensing signals from wearable devices, and the results pave the way for the development of next-generation intelligent and efficient wearable devices and e-skins.
