Abstract

The Artificial Accommodation System is a micro mechatronic system which will be implanted into the capsular bag to replace the human crystalline lens. Depending on the patients' actual need for accommodation, the system autonomously adapts the refractive power of its integrated optical element in a way that the projection on the patients' retina results in a sharp image. As the Artificial Accommodation System is an active implant, its subsystems have to be supplied with electrical energy. Therefore an inductive power supply system will be developed which is able to autonomously power the Artificial Accommodation System over a period of 24h and can be recharged wirelessly. This Paper describes the design process of the coils needed for inductively transferring power to the implant. It can be shown that by means of optimization it is possible to transfer 50 mW of power to the interior of the Artificial Accommodation System.

人工调节系统感应供电系统的设计

人工调节系统是一种微型机电一体化系统，它将被植入胶囊袋中，以取代人体的晶状体。根据患者的实际需要，该系统自动调整其集成光学元件的折射能力，从而使患者视网膜上的投影产生清晰的图像。由于人工调节系统是一种主动植入物，它的子系统必须提供电能。因此，将开发一种感应供电系统，该系统能够在24小时内自主为人工调节系统供电，并可以无线充电。本文介绍了电感式向植入体传输功率所需线圈的设计过程。结果表明，通过优化，可以将50兆瓦的功率传输到人工调节系统的内部。
