As shown in Figs. 7A and 7B, the flexible device 100 is provided with a bar-shaped terminal body, but the present invention is not limited thereto.

Here, the body of the flexible device 100 includes a case 101 which forms an outer appearance. The case may be divided into a front case and a rear case, and a case may be provided between the front case and the rear case Various electronic components can be embedded in the formed space.

In some cases, electronic components can be mounted on the surface of the rear case, and electronic components mounted on the surface of the rear case include a battery, a USIM card, a memory card, and the like that are detachable by the user.

The casing 101 of the flexible device 100 is provided with a display unit 151, an audio output unit 152, a camera (not shown), a user input unit 130, a microphone (not shown), an interface Can be arranged.

The display unit 151 occupies most of the main surface of the front case. The sound output unit 152 and the camera (not shown) are disposed in an area adjacent to one end of the both ends of the display unit 151, A user input unit 130 and a microphone (not shown) may be disposed in adjacent areas.

The user input unit 130 may have a button system for recognizing when the user applies pressure, There may be a touch method in which a sensor is provided and a command of a user is inputted only by the user's touch.

Then, the flexible device 100 may be thinned so that the flexible device 100 can be rotated by applying a force to the user's hand.

Therefore, the flexible device 100 of the present invention can be variously shaped according to the direction of the force of the hand held by the user.

FIGS. 8A and 8B show a first embodiment showing a bending direction of a flexible device according to an external force. FIG. 8A is a view showing a flexible device bending in a longitudinal axis, and FIG. 8B is a view showing a flexible device bending in a lateral direction.

As shown in Fig. 8A, when an external force is applied to the left and right sides of the flexible device 100, the flexible device 100 can be turned around the vertical axis.

In this case, since the central region of the longitudinal axis of the flexible device 100 is bent most, the most pressure is applied, and the edge region of the longitudinal axis is bent the least, so that the least pressure can be applied.

Therefore, the piezoelectric sensor disposed at the central region of the longitudinal axis of the flexible device 100 receives the most pressure, and the piezoelectric sensor disposed at the edge region of the longitudinal axis receives the least pressure, The current value measured from the piezoelectric sensor disposed in the center region of the vertical axis will be larger than the current value measured from the piezoelectric sensor disposed in the edge region of the vertical axis.

8B, when an external force is applied to the upper side and the lower side of the flexible device 100, the flexible device 100 can be centered on the horizontal axis.

In this case, since the central region of the horizontal axis of the flexible device 100 is bent most, the most pressure is applied, and the edge region of the horizontal axis is bent the least, so that the least pressure can be applied.

Therefore, the piezoelectric sensor disposed at the central region of the horizontal axis of the flexible device 100 receives the most pressure, and the piezoelectric sensor disposed at the edge region of the horizontal axis receives the least pressure, The current value measured from the piezoelectric sensor disposed in the central region of the abscissa axis will be larger than the current value measured from the piezoelectric sensor disposed in the edge region of the abscissa axis.

As shown in Fig. 9A, when an external force is applied in the diagonal direction between the horizontal axis and the vertical axis of the flexible device 100, the flexible device 100 can have an edge area.

In this case, since the edge area of the flexible device 100 is bent most, the most pressure is applied and the remaining area is hardly bent, so that only a very small pressure is applied or no pressure is applied at all.

Therefore, since the piezoelectric sensor disposed in the corner area of the flexible device 100 receives the most pressure, the current value measured from the piezoelectric sensor disposed in the corner area of the flexible device 100 is smaller than the current value measured in the piezoelectric sensor Will be greater than the current measured from the sensor.

9B, when an external force is applied in the diagonal direction between the horizontal axis and the vertical axis of the flexible device 100, the flexible device 100 may have a plurality of corner areas.

In this case, since the piezoelectric sensors disposed in a plurality of corner areas of the flexible device 100 are subjected to the greatest pressure, the current values measured from the piezoelectric sensors disposed in the multiple corner areas of the flexible device 100, Lt; RTI ID = 0.0 > a < / RTI > piezoelectric sensor disposed in the region.
