摘要

提出了一种啮齿类动物脑深部电刺激装置，并对其在常规刺激条件下的电特性进行了描述。只使用廉价的现成组件。该装置采用3.6 V 150 mAh锂离子聚合物电池，提供两个通道进行双相刺激，可长期运行30天以上。该刺激器配备无线充电模块，能够进行非接触式充电，因此操作时间延长至数月。刺激电极-组织界面在较宽范围内的阻抗变化对刺激信号和电源寿命的影响较小。

A Rechargeable Battery-Driven, More than 4 Weeks Runtime, Biphasic Bilateral DBS Unit for Rodents

A deep brain stimulation (DBS) unit for rodents is presented and electrically characterized under usual stimulation conditions. Only inexpensive off-the-shelf components are used. The device provides two channels for biphasic bilateral stimulation and proper long-term operation for more than 30 days using a 3.6 V 150 mAh Lithium-Ion polymer battery. Equipped with a wireless charging module, the stimulator is capable to be recharged contactless and therefore operation time is extended to months. Impedance variation of the stimulation electrode-to- tissue interface within a wide range have a minor impact on stimulation signals and power supply lifetime.
