The invention discloses an electrical stimulation system based on multimodal sensory feedback, which relates to the technical field of medical rehabilitation equipment and includes a sensor module, a digital signal processing module, a serial port transmission module and an electrical stimulation module; the sensor module is arranged on a prosthetic hand, The digital signal processing module is connected to the sensor module, receives various sensor signals collected and generates different electrical stimulation waveform codes through the transcutaneous electrical stimulation coding method based on multimodal sensory feedback, and then transmits them to the electrical stimulation module through the serial port transmission module , to perform real-time transcutaneous electrical stimulation on the evoked finger sensory area or alternative sensory area of the amputee to form six different sensations of touch, pressing, buzzing, vibration, numbness, and pain. The present invention combines the application of electric stimulation and induced finger sensation area, can give users a real natural feeling, can be applied to the control of prosthetic hands, and also establishes the sensory feedback of pain, combined with the detection of temperature and humidity, can avoid Damage to the prosthetic hand.
