Zusammenfassung:Provided are safety shoes enabling a wearer to be easily identified at night and prevent accidents in advance. Safety shoes equipped with a piezoelectric element according to an embodiment of the present invention include a sole; an upper coupled to an upper portion of an outsole; a battery provided inside the sole; a piezoelectric element provided inside the sole; a first sensor provided on either the sole or the upper and measuring the moving speed of the sole; a second sensor provided on the upper, located near the outer ankle bone of the wearer and measuring the speed of an object approaching the upper; a vibration motor provided on the sole; lighting provided on the upper; and a control unit configured to control the vibration motor by determining whether a first access condition and a second access condition are satisfied based on the information obtained by the first sensor and the second sensor, wherein the first access condition is a condition in which the speed measured by the second sensor is greater than the speed measured by the first sensor and the second condition is a condition in which the speed measured by the first sensor is not 0. 야간에 착용자를 쉽게 식별할 수 있고, 착용자가 안전사고를 사전에 예방할 수 있는 안전신발을 제공한다. 실시예에 따른 압전소자가 구비된 안전신발은, 밑창; 밑창의 상부에 결합되는 갑피; 밑창의 내부에 구비되는 배터리; 밑창의 내부에 구비되는 압전소자; 밑창 또는 갑피 중 어느 한 곳에 구비되고, 밑창의 이동속도를 측정하는 제1 센서; 갑피에 구비되되 착용자의 바깥복사뼈 인근에 위치되고, 갑피로 접근하는 물체의 속도를 측정하는 제2 센서; 밑창에 구비되는 진동모터; 갑피에 구비되는 조명; 및 제1 센서 및 제2 센서로 획득된 정보를 기반으로, 제1 접근 조건과 제2 접근 조건의 충족 여부를 판단하여 진동모터를 제어하는 제어유닛;을 포함하되, 제1 접근 조건은 제2 센서가 측정한 속도가 제1 센서가 측정한 속도보다 큰 조건이고, 제2 접근 조건은 제1 센서가 측정한 속도가 0이 아닌 조건인 것을 특징으로 한다.
