1. A measuring device for ambulation data, comprising:
- a bending sensor installed in a bottom of a shoe to sense a bending signal transmitted by bending of the bottom of the shoe and generate a voltage signal while a user is walking, the bending sensor includinga piezoelectric element to sense the bending signal, anda substrate installed on a surface of the piezoelectric element,wherein the piezoelectric element and the substrate overlap each other and an area of the piezoelectric element is greater than an area of the substrate;
a control unit electrically connected to the bending sensor to derive an ambulation parameter by processing the outputted voltage signal;
an inertial measurement unit installed in the shoe separately from the bending sensor and measuring at least one of walking direction, walking speed and acceleration of the user; and
a terminal to output the ambulation parameter transmitted from the control unit and the inertial measurement unit,wherein the bending sensor is placed at a middle portion of the bottom of the shoe between a toe part and a heel part of the shoe such that the bending sensor is placed under an arch part of the user'"'"'s foot and not directly pressed by a forefoot and a heel of the user.
