| Summary: | Microcurrent electrical therapy (MET) is a therapeutic method using low voltage microamperage stimulation. For the application in Indonesia, this method still needs policy, facility, and further research supports. This research is to develop the adequate microcurrent electrical stimulation instrument for medical research application for medical doctors in Indonesia. This one develops the open system microcurrent electrical stimulator, called OpenMCS and stimulation signal program called uStimS. The development of OpenMCS is based on PIC 16F877A microcontroller while the uStimS was programmed using MicroCode Studio-PICBASIC PRO version 2.46 software. The OpenMCS consists of the modality of therapeutic signal data processor circuit, 16-bit DAC with bipolar output, voltage to current converter, and the protection system circuit while the uStimS consists of the main program and therapeutic signals generator. The testing comprises OpenMCS performance test, protection system test, and pre-clinical test as the supporting test. The obtained results from output signal parameters have mean error of 0,28%, 0,83%, and 0% for amplitude, frequency, and pulse width. The protection system test shows the error rate of 0,59%, 0,70%, and 0,66% for exceeded current, exceeded electrical charge, and exceeded mean current. Pre-clinical test was held by comparing EEG signal from the patients, before and after the microcurrent stimulation at cranial nerve on P4 point. The result shows the increasing of alpha wave activity after stimulation. The accomplishment of this research results the adequate microcurrent electrical stimulation instrument for medical research, more excellent in feature and more economics than the similar products in market. The further development can be set to research on the advantage of microcurrent for health, microcurrent signal for degenerative disease treatment, microcurrent stimulator products for clinical usage, beauty treatment, and animal treatment. <br />
