本文介绍了一种低频无线电能传输系统（WPTS）的实验使用的压电换能器与磁铁尖质量作为接收器。采用溶胶-凝胶法制备了压电双晶片悬臂梁，并将其应用于可穿戴设备。该装置将施加的电磁场耦合到梁的机械横向振动，然后在连接到电端口的负载电阻两端感应电压。因此，这种耦合机制被称为磁机电（MME）效应。在磁通密度为100.3 μT时，在200 kΩ的电阻中产生3.4 μW的功率。示出了利用相同的压电谐振器用于能量收集和无线功率传输模式的潜力。
This paper presents experiments on a low-frequency wireless power transfer system (WPTS) using a piezoelectric transducer with a magnet tip mass as a receiver. The thin-film piezoelectric bimorph cantilever is fabricated by sol-gel processing with the aim to miniaturize the system for wearable applications. The device couples an applied electromagnetic field to the mechanical transverse vibration of the beam, which then induces a voltage across a load resistance connected to the electrical ports. This coupled mechanism is therefore referred to as the magneto-mechano-electric (MME) effect. A power of 3.4 μW is generated in a resistance of 200 kΩ at a magnetic flux density of 100.3 μT. The potential of utilizing the same piezoelectric resonator for both energy harvesting and wireless power transmission modes is shown.
