Abstract

A functional electrical stimulation system having a boost module to raise an output voltage of a primary power to a first preset voltage, an energy storage module, connected to the boost module, configured to store electrical energy of the first preset voltage, a central control unit configured to generate data packets of electrical stimulation parameters, and an electrical stimulation output channel, connected to the energy storage module, configured to receive the data packets of electrical stimulation parameters, analyze the electrical stimulation parameters from the data packets, convert electrical energy stored in the energy storage module to an electrical stimulation pulse corresponding to the electrical stimulation parameters and apply the electrical stimulation pulse to a part of a user. The functional electrical stimulation system can enhance flexibility and autonomy of an electrical stimulation pulse so that the user can select a personalized electrical stimulation pulse type according to his/her actual conditions.
