ABSTRACT

Objective:

To design and implement a low-power and portable transcranial direct current stimulator controlled by mobile phones.

Methods:

The constant current stimulation circuit was realized by a field effect transistor, which could output stable and adjustable low-intensity direct current, and the impedance detection circuit and the over-current protection circuit increased the effectiveness and safety of the stimulator. The control and real-time detection of the stimulation circuit was realized through a microcontroller, and the parameters' settings of the stimulator and the display and preservation of the actual stimulus information were realized through the Android software on the smartphone.

Results:

The output current strength and accuracy, maximum load, as well as the timing, device connection, stimulus information collection and display all achieved the expected goals.

Conclusion:

The design realized the mobile control of the stimulator, with portability, low cost and low power consumption, providing a new solution for wider applications.
