Problems solved by technology

[0003] At present, the application of the stretchable electric stimulation flagship in the field of two-way human-computer interaction is still blank. External temperature, electrotactile sensation, electrophysiological feedback, etc. directly affect the interaction between the machine and the human body, and the controllable behavior and intensity of the machine’s stimulation to the human body are still unclear. Further research is needed, the internal relationship between various electrical stimulation signals and human physiological behaviors needs to be revealed, and the stimulation behavior of flexible electrical stimulation devices on the human body needs to be deepened.
