Development And Experimental Study Of Multifunctional Micro Current Stimulator

With the increase of modern social life stress and working pressure, a variety of mental disorders and neurological problems are perplexing more and more people. Compared with traditional treatment methods, the use of micro current stimulation of this efficient, painless way to treat mental disorders are becoming mainstream. In this paper, we focus on the development of a wearable multi functional micro current stimulator based on Bluetooth control, and verify its validity.Described in this article wearable multi-function electrical stimulator of multi-function refers to: 1. With a variety of parameters, including the stimulation current intensity, stimulating the waveform, stimulating frequency, stimulating pulse width, stimulating time. It can help to develop targeted therapy for complex mental disorders; 2. With a combination of smart phones or smart watches with Bluetooth function. This device can receive control parameters data through Bluetooth module, and develop a Bluetooth control APP; 3. Can be used for the Cranial Electrotherapy Stimulation(CES), and Neuromuscular Electric Stimulation(NMES). 4. Constant current stimulation, current intensity does not change with the load resistance. After experimental verification, the experimental results show that the maximum error between the actual current and current theory only 0.94%.In view of the application of this device, two experiments were designed to test the validity of the cranial electrotherapy stimulation and neuromuscular electric stimulation. Electroencephalograph(EEG) power spectrum analysis and double factor analysis were performed on the pre and post CES, the results showed that the four kinds of stimulation waveforms of this device can improve the spectrum content of brain electricity and the effect is significant(p < 0.01). Double factor analysis were performed on the pre and post NMES and the results showed that the four kinds of stimulation waveforms of this device can improve the maximum isometric force of the upper arm circumference and muscle, and the effect is very significant(p < 0.01).
