Abstract

Functional electric stimulator (FES) is a device which is used to apply electric pulses to a muscle to trigger the\nmovement. FES is most effective in treating conditions like foot drop, Spinal cord injury and rehabilitation. FES helps to\nrestore mobility by applying electrical pulses to the paralyzed muscles so as to enhance that person’s ability to function and\nlive independently. Existing FES is of high cost thus not affordable by most of the people in India. FES thus designed is cost\neffective and is focused on rehabilitation. It has both current and voltage regulated stimulation system. It has dual\nmicrocontrollers. Arduino due is used as the master controller. It takes various parameters from the slave devices and triggers\nthe device accordingly. It also controls the device by mapping input on to the output. Arduino Uno is used solely for the\ngeneration of the stimulation signal. Serial peripheral interface (SPI) and I2C protocols are used to communicate between\nmaster and slaves. Due to its cost effectiveness it will be of great use for middle class community.
