Abstract:
1. An apparatus for stimulating a living body comprising: a light source unit which irradiates a pulse-type optical signal for generating a pulse-type electrical signal; a photovoltaic cell unit which generates the pulse-type electrical signal using the pulse-type optical signal; and an electrode unit which is electrically connected to the photovoltaic cell unit, the electrode unit receives the pulse-type electrical signal directly from the photovoltaic cell unit and stimulates the living body using the pulse-type electrical signal, wherein the photovoltaic cell unit transmits information about an intensity of the pulse-type electrical signal to the light source unit, and wherein the light source unit receives the information about the intensity of the pulse-type electrical signal from the photovoltaic cell unit and controls an intensity of the pulse-type optical signal based on the intensity of the pulse-type electrical signal.
