摘　　要：为解决光遗传学系统体积大,传输效率低,使用局限性大的问题,通过变量分析的方法,设计了一种基于无线供电的光遗传系统优化方案。该方案具有功耗低,结构简单,响应速度快,效率高且光强输出稳定的优点。仿真及实验结果表明:在两线圈距离为10 mm时,蓝光LED的两端电压能达到3.7 V。可见该优化方案结合光遗传系统的实际情况,通过实验优化系统硬件结构,显著提高了无线传输的稳定性。In order to solve the problems of large size,low transmission efficiency,and large limitation of optogenetics systems,a method of variable analysis was used to design an optimization of optogenetic systems based on the wireless powering,with the advantages of low power consumption,simple structure and fast response,high efficiency and stable light output.Simulation and experimental results show that:When the distance between the two coils is 10mm,the voltage across the blue LED can reach 3.7V.It can be seen that this optimization scheme combines the actual conditions of the optical genetic system and optimizes the hardware structure of the system through experiments to significantly improve the stability of wireless transmission.
