Miniature wireless interactive transcranial electrical stimulation system

The invention relates to a miniature wireless interactive transcranial electrical stimulation system, which ensures the basic functions (five stimulation modes of tDCS, tACS, tPCS, tRNS and Sham), adjustable current amplitude, adjustable current frequency, adjustable duty ratio and adjustable stimulation duration during stimulation, and has the advantages of simple structure, low cost and the like. On the premise that a mobile terminal remotely sets stimulation parameters, monitors the stimulation parameters in real time and records the stimulation history in good operation, closed-loop control of current is achieved, it is guaranteed that stimulation current is constant when impedance changes, the impedance detection and overcurrent protection functions are achieved, use safety is guaranteed, the size is smaller, and the mutual information transmission speed is higher. The small size is easy to integrate with other equipment in combined treatment; the battery is integrated with the device, so that the chargi
