Abstract: Spintronic sensors with excellent sensitivity to magnetic field, low power consumption, compactness and CMOS compatibility can be one of the critical sensing devices supporting the Internet of Things (IoT) and enabling smart living. Smart living is a trending and connected lifestyle that envisions efficient and sustainable energy utilization, stable and reliable power supply, intelligent and coordinated transportation and mobility, and personalized and cost-effective healthcare. Its realization needs the IoT which is a compelling platform connecting trillions of sensors and collecting data for connectivity and analytics. IoT is more advanced than traditional monitoring systems where limited sensors and wired communication can merely collect fragmented data in the application domains. In this paper, we review successful applications of individual spintronic sensors as sensor nodes in electrical current sensing, transmission and distribution lines monitoring, vehicle detection, and biodetection. The wireless spintronic sensor networks (WSSNs) working at the massive interconnected network level are proposed and illustrated to implement IoT and fulfill the promises of smart living in new energy and new applications. This technology will facilitate the intelligent surveillance and management over building, power grid, transport, and healthcare. This talk hopefully will shed some insights for realizing smart living through the integration of IoT with spintronic sensor technology.

Biography: Philip W. T. Pong is a chartered physicist, a chartered electrical engineer, and a chartered energy engineer.
