Tilt sensor and fabrication method of the tilt sensor

PURPOSE: A tilt sensor and a manufacturing method thereof are provided to reduce toxic material generation and manufacturing costs because an additional semiconductor process is not existed. CONSTITUTION: A tilt sensor comprises substrates(110) facing each other, nano wires(120), a current applying terminal(130), and a voltage measuring terminal(140). The nano wires are respectively formed in each substrate, thereby contacting to each other and comprising a piezoelectric characteristic. The current applying terminal applies a current between the substrates. The voltage measuring terminal is arranged in a different position on the substrate and measures a voltage between the substrates.
