Device for improving in vivo penetration of molecules into cells, comprising a generator of square unipolar electric pulses, an electrode device electrically linked to the generator, and a means ( 8 ) of injecting the active agent into the tissues. The generator is adapted to generate a signal consisting of a series of square pulses at a low and constant voltage ( 611 ) in PWM (Pulse Width Modulation) mode in accordance to the form of the required pulses. The signal is used to divide a constant voltage current ( 631 ) output by a direct voltage source ( 530 ) and generate a current ( 641 ) having a required voltage ( 130 ).
