摘要
电刺激可以促进细胞的生长及分化,进而促进组织的生长及伤口的愈合。文中采用AFG3102型函数发生器,结合Visual Studio 2010开发平台以及TekVISA函数库编写上位机软件,控制其输出任意目标波形。该波形经过电压放大器放大,可以直接应用于细胞培养,形成对细胞的恒压刺激。该细胞电刺激器可以提供频率可调、幅值（0~15 V）与波形可变的刺激信号,实现对细胞生长的恒压刺激。
The electrical stimulating signal can promote cell migration,proliferation and differentiation,and tissue growth. In the paper,AFG3102,an arbitrary function generator（Tektronix）,was used to generate the stimulating signal with arbitrary shape through control software in the computer. This signal can be amplified and then used to stimulate cells directly in the constant voltage mode.The results show that the stimulator can provide stimulating signals with arbitrary waveform in the amplitude ranging from 0 V to 15 V.And the instrument designed and implemented can meet the need of stimulating cells with target waveforms and voltages.
