Abstract:
Objective To design a stimulating instrument for physiology experiment.Methods A sine wave was produced by a high frequency oscillator,and then the sine wave increased in voltage by a transformer to accord with the maximal range needed.Afterwards,the increscent sine wave became a direct current signal with high voltage by a rectifier and a filter.Finally,the signal became a stimulating impulse to be exported by a switch,which was controlled by a controlling signal with adjustable frequency and width.Results Voltage range adjusted between 1 and 80V;Frequency adjusted between 0.1 and 200Hz;Impulse width adjusted between 0.1 and 5ms.Conclusion The stimulating instrument designed can be used to do electricity stimulating experiment in Physiology.
