In this paper, personal electrical stimulation medcial devices using bioelectrical stimulating was developed. Therapy effect of RET(resistive electric transfer) was more effective than CET(capacitive electric transfer), but CET was adopted because of safety issue. Then, the optimum parameters that may be effective in thin skin or facial wrinkles was set. For example, the frequency of the pulse voltage for stimulation is 1.8[MHz], burst frequency is 7[kHz] or 400[Hz], the development of devices was to have ON/OFF control and frequency control. When burst frequency was adjusted 7[kHz], heat was generated in the electrode. The case of 400[Hz] the heat was little generated. The microcontroller ATmega128-based experimental results show that the proposed personal high frequency electrical stimulation devices can be applied to medical equipment using therapy effect successfully.
