The control unit 260 controls the state detection unit 210, the communication unit 220, the sensor module failure check unit 230, the heating control unit 240, and the data storage unit 250.

In addition, the pressure sensor 212a using the nanowires of this embodiment includes the nanowires 10, the input terminal 20, the sensing unit 30, the extension unit (not shown), and the control unit (not shown).

The nanowire 10 is made of a metal material having a single crystal structure, and is made in the form of a wire having a nano size, that is, both a cross section and a length.

The input end 20 is coupled to one end, that is, the right end of the nanowire, and at this time, the left end of the nanowire is fixed.

At this time, an external load (F1) is applied to the input terminal (20), and this load is transmitted to the nanowire (10).

The sensing unit 30 senses whether the nanowires 10 vibrate when a compressive load is applied to the nanowires 10, and outputs a signal corresponding thereto.

When the nanowire 10 vibrates, a pulse is output, and when it does not vibrate, a pulse is not output.

The sensing unit 30 may be configured in various forms, for example, as shown in FIG. 5, by disposing a contact sensor (not shown) at a position within the amplitude (h) range of the nanowire 10, the nanowire It can also be configured to sense the vibration of (10).

The extension part (not shown) is for applying a tensile load in the longitudinal direction of the nanowire 10 in order to recover the nanowire 10 deformed by the compressive load, and is connected to the input end 20 .

In this case, when a force F2 is applied to the input end 20 in the right direction from the extension part (not shown), this force is transmitted to the nanowire 10 through the input end 20, and thus the nanowire 10 After elongation, when the tensile load applied to the nanowire 10 is removed, the nanowire 10 recovers to its initial state while elastically behaving.

The control unit (not shown) receives the signal output from the sensing unit 30 and measures the pressure applied from the outside according to the signal.

When only one nanowire 10 is provided, when a pulse is output from the sensing unit 30, it means that the compressive load applied to the nanowire 10 is greater than or equal to the compressive load causing the nanowire 10 to vibrate. .

In this case, for more accurate pressure measurement, it is preferable to install a plurality of nanowires 10 in parallel.

As described above, the present invention uses the characteristics of the nanowire in the pressure sensor 212a, that is, the cross-sectional area of the nanowire is very small, so that it responds sensitively even to a very small external force, so that the magnitude (pressure) of the external force can be accurately measured. It provides a technical advantage that can be measured in a precise way.

In the case of the present invention, a nanowire made of copper having a cross section of 2.16 × 2.16 nm and a length of 27 nm was used.

When a compressive stress of a certain size or more is applied to a nanowire having a single crystal structure, vibration occurs in the nanowire, and when the nanowire is stretched again, the nanowire behaves elastically and recovers to its initial state.

At this time, the compressive stress at which the vibration is generated is determined according to the size (sectional area and length) of the nanowire and the material.

In addition, although copper nanowires have been exemplified above, the same behavior is exhibited when nanowires having a single crystal structure are formed using other metals (transition metals) without being limited thereto.
