Abstract:
Study the key technology of head-mounted pulsed transcranial electrical stimulator and the design of APP display control system. With STM32 as the control core, focus on the head-worn, high precision and other characteristics, to overcome the disadvantages of difficult to carry, traditional type button is not easy to control; on the basis of the traditional transcranial instrument circuit design, optimize the system power input, pulse signal shaping, software programming and other aspects, build Bluetooth communication and APP control real-time display control system; by adjusting the duty cycle of PWM wave to output 0~2mA adjustable low-frequency current, headset appearance design optimized generation by generation, adjustable size. The experimental debugging proves that the instrument has high precision, strong load adaptability and high practical value.
