Abstract: An electrical stimulation control circuit including a pulse generator, a processing circuit and an electrode is provided. The pulse generator is configured to generate a switching signal. The processing circuit generates an energy signal according to the switching signal. The electrode is configured to contact the skin of a living body and includes a first comb electrode and a second comb electrode. The first comb electrode receives the energy signal and includes a plurality of first electrodes. The first electrodes are electrically connected to each other and extended along a first direction. The second comb electrode receives a ground signal and includes a plurality of second electrodes. The second electrodes are electrically connected to each other and extended along a second direction opposite to the first direction. The first electrodes and the second electrodes are arranged in a staggered manner and electrically insulated from each other.
