  • Electrical living body stimulation signal waveform generation device and electrical living body stimulation device
    Patent number: 9283384
    Abstract: An electrical living body stimulation signal waveform generation device includes a waveform generation unit that generates a low-frequency pulse signal wave and a high-frequency signal wave individually, and a waveform synthesis circuit that superimposes the high-frequency signal wave on the low-frequency pulse signal wave during an ON period of the low-frequency pulse signal wave to form a synthesized wave having a waveform in which a level gradually rises from a point of time when the superimposition is started and the ON period and an OFF period are continuously repeated, wherein the synthesized wave is given as an electrical stimulus to a living body.
    Type: Grant
