Provided is a displacement measurement sensor. The displacement measurement sensor comprises: a first housing in which a sensor board is placed; a second housing placed apart from the first housing; and a third housing of which one end is engaged with the first housing, and the other end is engaged with the second housing, and in which a flex sensor is placed. The third housing is made of flexible materials so the external shape of the third housing is changed in accordance with changes in the external shape of a subject on which the third housing is mounted. When the external shape of the third housing is changed, the external shape of the flex sensor placed in the third housing is also changed, so the resistance value of the flex sensor is changed as well. Accordingly, a user can measure the changes in the resistance value of the flex sensor, and measure the changes in the external shape of the subject. The present invention aims to provide a displacement measurement sensor which has enhanced durability.

    변위측정센서가 제공된다. 상기 변위측정센서는 내부에 센서 보드가 배치되는 제1 하우징, 상기 제1 하우징과 이격되어 배치되는 제2 하우징, 및 일단이 상기 제1 하우징과 결합되고, 타단이 상기 제2 하우징과 결합되며, 내부에 플렉스(flex) 센서가 배치되는 제3 하우징을 포함하되, 상기 제3 하우징은 플렉시블(flexible)한 소재로 이루어져, 상기 제3 하우징이 장착된 대상체의 외형 변화에 따라 상기 제3 하우징의 외형이 변화되고, 상기 제3 하우징의 외형이 변화되는 경우, 상기 제3 하우징 내부에 배치된 상기 플렉스 센서의 외형 또한 변화되어 상기 플렉스 센서의 저항값이 변화되며, 상기 플렉스 센서의 저항값 변화를 측정하여 상기 대상체의 외형 변화를 측정할 수 있다.
