The present invention relates to a sensor-integrated touch input apparatus, and more particularly, to a sensor- integrated touch input apparatus, in which, in a touch input device (for example, a touch screen or a touch pad) in which a user inputs an operation or location command using a pointing object (for example, a finger or an illustration tip), a sensor unit, including a plurality of force sensors, is integrally included in the touch input device and a protection unit is formed in the touch input device, so that each of the plurality of force sensors has the same sensing performance, thereby minimizing the distortion of a detected signal. Further, the present invention relates to a method of acquiring the location and intensity of an acting force using the sensor-integrated touch input apparatus at the same time.

The present invention relates to a touch input structure for detecting intensity and an action position of a pressing force, and more specifically, to a touch input structure, a touch input apparatus, and a touch detection method, which can detect intensity and an action position of a pressing force based on change of a space between an upper layer and a lower layer of the touch input structure or strain of the upper layer.
Abstract:
The present invention relates to a carbon nanotube composite in which micro pillars having vertical shapes are formed, a method of manufacturing the carbon nanotube composite, and a tactile sensor including the carbon nanotube composite. The carbon nanotube composite includes a polymer matrix including a base and a plurality of micro pillars extended and protruded from the base and carbon nanotubes mixed with the polymer matrix. The carbon nanotubes can be easily modified and a change in the resistance of the carbon nanotubes can be maximized using the elasticity of the micro pillars that are easy to be compressed or bent.
Abstract:
The present invention relates to a carbon nanotube composite having improved pressure-resistance sensing sensitivity, a method of manufacturing the carbon nanotube composite, and a pressure sensor including the carbon nanotube composite. A polymer matrix of polydimethylsiloxane, carbon nanotubes, and silver nanoparticles are mixed at a mass ratio of 1 : 0.0018 to 0.0022 : 0.032 to 0.048, and the carbon nanotube and the metallic nanoparticles are uniformly distributed over the polymer matrix. The silver nanoparticles are not attached to a surface of the carbon nanotube, but the carbon nanotube and the silver nanoparticles are uniformly distributed over the polymer matrix. Accordingly, the linearity of the carbon nanotube can be improved, the carbon nanotube composite has improved sensing sensitivity, and the carbon nanotube composite can be manufactured very simply.
