In this paper, we examined the working process of taste cells and especially the sour taste, studied the signal corresponding to this taste in the case taste cell, used the recorded samples, simulated the signal corresponding to the sour taste by using the soft wares and mathematical techniques, converted the signals from analogue to digital and obtained the signal equation. Finally we designed the micro-controller circuit corresponding to this signal. This circuit can be designed and implemented on an IC that can be fixed on the taste cells of the sour taste and stimulates the taste cells this way and the neurons send the electric message resulting from the stimulation to the brain and the person will feel the sour taste without having the intact taste cells.
