Recently, performance of a mobile phone has increased dramatically, and it is possible to integrate various biotechnologies into the mobile phone. Among the various biotechnologies, a transcutaneous electrical nerve stimulator has many advantages such as improve the circulation of blood and suppress a pain. To integrate the stimulator in the mobile phone, it is necessity to make small, low power, and safe module. In this paper, the transcutaneous electrical nerve stimulation module was designed and implemented by small boost converter. To reduce the power consumption, the external ADC was used to measure the value of the charged energy. Also, the module limits the maximum transmit power by tank capacitor value to inprove safety. To confirm the operation of designed module, an arm processor was used to control the module. The implemented module consumes only 6.6 ㎽ (without CPU) at normal stimulus mode.
