The invention discloses an electrical stimulation 
system based on 
multimodality perception feedback, and relates to the technical field of 
medical rehabilitation apparatuses. The electrical stimulation 
system comprises a sensor module, a 
digital signal treatment module, a 
serial port transport module and an electrical stimulation module, wherein the sensor module is arranged on a 
prosthetic hand;the 
digital signal treatment module is connected with the sensor module and is used for receiving collected sensor signals, generating different electrical stimulation 
wave shape codes in a 
percutaneous electrical stimulation encoding manner based on 
multimodality perception feedback, and transmitting the electrical stimulation 
wave shape codes to the electrical stimulation module through the 
serial port transport module to perform real-time 
percutaneous electrical stimulation on the evoked finger 
sensation region or replaced 
sensation region of an amputee so as to form six kinds of differentfeelings of touch, pressing, buzz, vibration, numbness and pain. According to the electrical stimulation 
system, through combination of electrical stimulation and application of the evoked finger 
sensation region, real natural feeling can be provided for users, the electrical stimulation system can be used for operating and controlling the 
prosthetic hand, pain feeling feedback can also be established, and through combination of temperature and 
humidity monitoring, the damage of the 
prosthetic hand can be avoided.
