摘要
无线神经刺激与记录系统对于长期研究动物行为、治疗慢性神经性疾病具有重要意义。头台神经植入是目前常用的神经刺激方法之一。在这项工作中，开发了一种基于家庭的无线电力传输(WPT)系统，为3d打印的头台供电，该头台由接收器(RX)线圈、整流器和用于光遗传刺激的发光二极管(LED)组成。多层发射机(TX)线圈设计用于在28.5 cm × 18 cm的住宅面积上提供电源。与其他最先进的系统相比，该系统使用较少的顶级谐振器，能够在5厘米距离内通过空气介质实现41.7%的最高效率。
A Novel 3-D Printed Headstage and Homecage based WPT System for Long-term Behavior Study of Freely Moving Animals
Wirelessly powered neural stimulation and recording system is crucially important for the long-term study of the animal behaviors for the treatment of chronic neuropathic diseases. Headstage based neural implant is one of the popular methods to stimulate the neurons. In this work, a homecage based wireless power transfer (WPT) system is developed to supply power to a 3-D printed headstage which consists of a receiver (RX) coil, a rectifier and a light-emitting diode (LED) for optogenetic stimulation. A multilayer transmitter (TX) coil is designed to provide power over the 28.5 cm × 18 cm homecage area. The proposed system is able to achieve a maximum of 41.7% efficiency at 5 cm distance through air media using less number of headstage resonators compared to the other state-of-the art works.
