Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a linear sensor,

More particularly, the present invention relates to a linear sensor and a manufacturing method thereof, and more particularly, to a linear sensor and a manufacturing method thereof, and more particularly, And more particularly, to a linear sensor which is easy to install and use without inducing a foreign object and a manufacturing method thereof.

2. Description of the Related Art Generally, various home and industrial appliances include a temperature sensor for sensing temperature, a humidity sensor for sensing humidity, a smell sensor for sensing smell, a taste sensor for sensing taste, And the like are incorporated or installed.

For example, as shown in Fig. 1, the temperature sensor and the humidity sensor include a pair of electrode terminals 13 and 14 disposed opposite to each other, a detecting element 12 formed between the electrode terminals, Lead wires 15 and 16 to be connected, and an insulating coating layer 17b made of an electrically insulating resin material coated on the outer peripheral surface of the lead wire. The other end of the lead wires 15 and 16 is formed with an insulating coating layer non-formed portion so that a connection terminal for connection with the sensing signal receiving side is formed.

The detecting element 12 is constituted by a temperature detecting element (or a thermosensitive element) when constituted by a temperature sensor and constituted by a humidity detecting element (or a humidity detecting element) when constituted by a humidity sensor.

The temperature sensing element may be a negative temperature coefficient (NTC) thermistor element having a resistance temperature coefficient that decreases as the temperature rises or a positive temperature coefficient (PTC) characteristic having a positive resistance temperature coefficient temperature coefficient thermistor element.

The humidity detecting element may be a resistance type humidity detecting material whose resistance varies according to humidity, and a capacitance type humidity detecting material whose capacitance varies depending on humidity.

Usually, the resistance type humidity detecting substance uses a substance that changes resistance depending on humidity such as ceramics or an inorganic substance, and the humidity detecting substance uses a moisture-sensitive polymer such as PMMA (POLYMETHYLMETHACRYLATE).

Such sensor devices, such as temperature sensors and humidity sensors, have been gradually reduced in size and are conveniently used for various purposes, but they have various limitations and are difficult and inconvenient to apply to specific fields or devices.

For example, in a smart garment configured to sense an external stimulus and to respond to a set condition by itself, the heating apparel as a basic garment needs a warmth sensor for performing temperature control and a humidity sensor for performing humidity control, The temperature sensor and the humidity sensor are bulky and hard to install, which not only reduces the foreign body sensation but also exposes the exterior of the garment, thereby causing the aesthetics to be damaged.

In addition, since the conventional sensor device does not have elasticity, there is a problem that the feeling of wearing of clothes is severely impaired. In addition, the conventional sensor device has a limitation that it can not be applied at all because it is easily damaged or broken when it is installed in a portion where the length is increased or the volume is increased due to an external force applied during wearing or use.

On the other hand, various apparel such as wearable computers, healthcare apparels capable of remote diagnosis, and digital uniforms have been proposed as smart apparels. Considering that such smart apparels are worn on the human body, proper temperature and humidity control functions Therefore, in order to develop smart apparel, a sensor device capable of sensing the performance without hindering the activity and wearing comfort is desperately required.

Particularly, in the conventional sensor device, since the electrode terminals 13 and 14, the detecting element 12, and the insulating coating layer 17b are manufactured and assembled to the lead wires 15 and 16, the manufacturing process is complicated, But also the productivity is low.
