US 10,478,286 B2 · Artificial vestibular organ system

Abstract

An artificial vestibular organ system includes an artificial semicircular canal; a liquid filled in the artificial semicircular canal; artificial hair for sensing movement of liquid in the artificial semicircular canal; a signal conversion unit for converting an electrical or magnetic signal generated from the artificial hair into a body stimulation signal; a body stimulation pulse generation unit for transmitting the body stimulation pulse converted by the signal conversion unit to the ampulla; and a power unit. The artificial hair can be constituted in a pressure sensing manner or in a speed sensing manner for sensing the flow rate. The pressure sensing type can be formed of flex sensor, a piezoelectric sensor, or an FSR sensor, and the velocity sensing type can include rotary wings rotated according to the flow of the liquid or a speed measuring instrument for measuring the rotating speed of the rotary wings.

Dependent claims

An artificial vestibular organ system comprising:

an artificial semicircular canal;
an artificial hair in the artificial semicircular canal configured to generate an electrical or magnetic signal according to changes in position;
and
a body stimulation pulse generation unit configured to generate a body stimulation pulse using the electrical or magnetic signal generated from the artificial hair to transmit the body stimulation pulse to an ampulla,
wherein the artificial hair is disposed on one surface of an interior of the artificial semicircular canal and is configured to sense a movement of a liquid.
