无线能量传输是实现未来传感器节点的关键技术。目前的方法是基于感应链路或RF遥测，两者在实现更高的功率密度方面都面临限制。多铁遥测技术可以解决这一挑战，并为远程供电提供新的方法。介绍了一种在磁致伸缩载体上集成压电薄膜以实现高效多铁性功能的方法。各种多层架构的输出功率性能进行了研究。多铁性柔性叠层随后与二极管整流器拓扑和存储电容器集成以产生期望的输出。结果表明，新的功率遥测机会与先进的材料堆栈与柔性封装集成。
Wireless power transmission is becoming a key technology in realizing future sensor nodes. Current approaches are based on inductive links or RF telemetry, both face limitations in achieving higher power densities. Multiferroic telemetry can address this challenge and provide a new approach for remote powering. This paper describes an integrated piezoelectric film on magnetostrictive carriers to achieve highly-efficient multiferroic functions. Various multi-layered architectures were investigated for output power performance. The multiferroic flexible stacks subsequently integrated with diode rectifier topologies and storage capacitors to generate the desired output. Results demonstrate new power telemetry opportunities with advanced material stacks with flex package integration.
