对于生物医学应用,可植入设备需要外部或内部电源来运行。电线和电池的限制强调了植入物需要无线功率传输(WPT)系统。在本文中,一个灵活的接收器模块提出了WPT应用使用聚萘二甲酸乙二醇酯(PEN)。WPT系统在4 MHz工作频率下,在5 mm距离处通过空气实现0.15%的最大功率传输效率(PTE)。通过6层组织模型评价了拟定WPT系统的比吸收率(SAR)。
For biomedical applications, implantable devices require an external or internal power source to operate. The restricting wires and battery limitations emphasize the need for wireless power transfer (WPT) system for the implants. In this paper, a flexible receiver module is presented for WPT applications using Polyethylene Naphthalate (PEN). The WPT system achieve a maximum power transfer efficiency (PTE) of 0.15% at 5 mm distance through air at 4 MHz operating frequency. The specific absorption rate (SAR) for the proposed WPT system is evaluated through a 6-layer tissue model.
