Abstract

An electronic stimulation device is adapted for electrically stimulating a target zone of an organism with relative low pain sensations without generating relative much sensations of paresthesia. The electronic stimulation device comprises at least one electronic stimulation unit. The electronic stimulation unit includes at least one first electrode and at least one second electrode. The electronic stimulation unit receives a high-frequency electrical stimulation signal to impel the first electrode and the second electrode to generate an electric field. The range of the electric field covers the target zone, and the electric field strength ranges from 100 V/m to 1000 V/m. The frequency of the high-frequency electrical stimulation signal ranges from 200 KHz to 1000 KHz.
