1. A sensor for measuring a tilt angle based on electronic textile, comprising:
- a plurality of textile electrodes disposed at predetermined uniform intervals on a textile surface;
a textile conductive wire of which one end is connected to a center between the plurality of textile electrodes;
a metal bead connected to another end of the textile conductive wire to thereby be connected to the textile surface and suspended at a distance from the textile surface; and
a measurement means to calculate a tilt angle of the metal bead relative to a plane including at least one of the plurality of textile electrodeswherein the measurement means calculates the tilt angle of the metal bead using capacitance between each of the two different textile electrodes and the metal bead, andwherein the measurement means measures capacitance of each of the two conductive wires that constitute the textile conductive wire and thereby determines a difference in the measured capacitance between the two conductive wires as capacitance between the textile electrode and the metal bead.
