由压电层和磁致伸缩层组成的磁电(ME)换能器最近被证明是微型植入式医疗设备(IMD)无线能量传输(WPT)的接收器。由于其复杂的机械-磁-电相互作用，需要研究在较小的IMD内对ME换能器进行生物兼容涂层和封装的方法，以实现最佳的ME响应。本文介绍了生物相容性涂层和包装的聚二甲基硅氧烷(PDMS)对ME响应的影响。用508µm厚的压电层制作了3个杆状~5×1×1 mm~3ME换能器。在空气中，添加~35微米的PDMS涂层使接收功率(PL)降低19.4%(131.04微瓦比105.62微瓦)。ME传感器安装在印刷电路板(PCB)上，并安装在定制的3D打印支架内。印刷电路板安装对ME传感器的PL没有显著影响，但3D打印支架在水介质中测量时，将PL从112.89微瓦显著降低到39.02微瓦。
Magnetoelectric (ME) transducers, composed of piezoelectric and magnetostrictive layers, have recently been demonstrated as a receiver in wireless power transfer (WPT) to miniature implantable medical devices (IMDs). Due to their complex mechano-magnetic-electric interactions, methods for biocompatible coating and packaging of ME transducers within a small IMD need to be investigated to achieve optimal ME response. This paper describes the effects of biocompatible coating and packaging using Polydimethylsiloxane (PDMS) on ME response. Three bar-shaped ~ 5×1×1 mm3ME transducers were fabricated with a 508 µm thick piezoelectric layer. In air, adding ~ 35 µm of PDMS coating reduced the received power (PL) by 19.4% (131.04 µW vs. 105.62 µW). The ME transducer were mounted on a printed circuit board (PCB) and inside a custom 3D-printed holder. The PCB mounting had no significant effect on ME transducer PL, but the 3D-printed holder considerably reduced PLfrom 112.89 µW to 39.02 µW, when measured in a water medium.
