| Summary: | 碩士 === 國立暨南國際大學 === 生物醫學科技研究所 === 93 === For the past decade or so, the light or micro-current stimulation has gone from being an experiment phase to a healing instrument of our life. Although the instrument has great healing for human, it is singular to each other. If the two singular stimulations are to combine to form one new instrument, it will have better effect and more choice.
In this study, we design a driver circuit that is multi-function and has a function of sweep frequency for combined light with micro-current stimulation device. We use the constant current circuit to design the output stage and to simplify the driver circuit and output stage of light and micro-current system. In the part of control, we use the microchip (PIC) to control the system. The frequency, time and power of the stimulation parameter were chose and stimulate by swept-frequency. In stimulation of light, the frequency is scan, 73, 146, 292, 584, 1168, 2336, 4672Hz and power is from 0 to 5mW/cm2. In stimulation of micro-current, the frequency is scan, 0.3, 9, 30, 292Hz, and the power is 0 to 1mA. The stimulation time of system is 0 to 20 minutes. By the combination of firmware and hardware, the light and micro-current stimulation instrument were applied to therapy and looks treatments that can be safer and more profitable.
