摘要：

Internet of Things (IoT) has been considered as the next industry revolution.Current IoT platforms are normally based on external power supply orbatteries. In this talk, Prof. Liu will propose a novel IoT platform based onspintronics. The platform consists of self-independent power supply forwearable sensing, computing, and communication based on micro electromechanical systems (MEMS), and spintronic logic gate with extremely lowpower consumption. He will demonstrate a flexible MEMS that can collectthe energy of sound¹ . He will also demonstrate a spintronic logic gate basedon electric field modulated motion of magnetic skyrmions²
