| Abstract |
Electrostimulators, a type of electromedicine that applies a weak current to the body through electrodes, have proven to be effective in many types of treatments, including muscle strengthening, depression, insomnia, and epilepsy. One of the biggest challenges of these electrostimulators is how to remove the residual charge that remains after stimulation, and researchers are working on this. In this paper, an improved active charge balancing method is studied for an electric stimulation system that is safe, has a low device count, and consumes less power. PSPICE was used to simulate the system, and it was implemented using breadboard and PCB to verify the actual behavior. The implementation and simulation results showed that the system is safe for electrode impedance changes of about 55%, the number of used component is reduced by 20 compared to previous study, and the power consumption is reduced by 55%. |
