1. A posture monitoring device configured to monitor a posture by measuring a degree of stretching of a first part and a second part of a dorsal part which are divided by a spinal column, the posture monitoring device comprising:
at least one first elastic resistance element which includes a pair of first electrodes respectively formed on opposite ends of each of the at least one first elastic resistance element, and a first conductive material that has elasticity and is connected to each of the pair of first electrodes, the at least one first elastic resistance element disposed in a longitudinal direction of the spinal column and configured to be attached onto or inserted into skin of the first part, the first conductive material configured to be formed as a string through a combination of elastic materials and conductive nanoparticles, and to exhibit electrical resistance that changes according to a mechanical strain occurring in the at least one first elastic resistance element;
at least one second elastic resistance element which includes a pair of second electrodes respectively formed on opposite ends of each of the at least one second elastic resistance element, and a second conductive material that has elasticity and is connected to each of the pair of second electrodes, the at least one second elastic resistance element disposed in the longitudinal direction of the spinal column and configured to be attached onto or inserted into skin of the second part, the second conductive material configured to be formed as a string through a combination of elastic materials and conductive nanoparticles, and to exhibit electrical resistance that changes according to a mechanical strain occurring in the at least one second elastic resistance element;
a power supply configured to apply a current or a voltage to the at least one first elastic resistance element and the at least one second elastic resistance element through the electrodes formed on both ends of each of the at least one first elastic resistance element and the at least one second elastic resistance element; and
a meter configured to be connected to each electrode of the pair of first electrodes and the pair of second electrodes in order to measure current or voltage flowing in the at least one first elastic resistance element and current or voltage flowing in the at least one second elastic resistance element.
