Conformity Evaluation of Cranial Electro-stimulation Prototype with Low Current Intensity and Smartphone Application

We designed cranial electro stimulation with a low current intensity, which is applied to the head indirectly using direct current intensity. Unidirectional transcranial stimulation is a non-invasive brain stimulation method that has been shown to be effective in modulating cortical excitability and guiding human perception and behavior. The purpose of this research is to design a low-current-intensity cranial electro-stimulation therapy device that is affordable, dependable, and feasible. The CES has a frequency range of 10, 13, and 15 Hz and treatment times of 15, 30, and 45 minutes. The CES generates a current intensity of 0.25, 0.5, 0.75, and 1 mA. The design of CES prototypes was tested at Balai Pengamanan Fasilitas Kesehatan (BPFK) Jakarta, Indonesia, which includes electrical safety measurement, performance testing, and battery reliability. The BPFK Jakarta declares that the test meets the requirements of the testing method and that the tool has passed the test. In addition, the tool has been issued a certificate with no YK.01.03/XLVII.2/PK/2022.
