Abstract:
This article describes a complete system prototype to be used in aesthetic mesotherapy. The system is composed by two main blocks: a Master block, whose chief component is a CPU, which provides the user interface and a Slave block, implemented with a micro controller and a wave generator, which produces the appropriated voltages and currents compatible with the mesotherapy treatments. The whole system is powered by a 12V power supply and the output signal has a voltage that range between -54 V and 54 V. The output signal is composed by the overlap of two frequencies: the first one is selected in the range from 1.2 kHz to 1.8 kHz and the second one is in the range from 0.07 Hz to 2 Hz. The system is being tested in clinical environment with real patients showing very good promising results.
