1. A unit sensor comprising:
- an upper electrode layer including a polymer substrate, an upper electrode embeddedly formed in the center of the polymer substrate in a relatively wide width, and a signal transmission line embeddedly formed in the polymer substrate in a relatively narrow width such that the signal transmission line extends in the side-to-side direction of the upper electrode;
a lower electrode layer including a polymer substrate, a lower electrode embeddedly formed in the center of the polymer substrate in a relatively wide width, and a signal transmission line embeddedly formed in the polymer substrate in a relatively narrow width such that the signal transmission line extends in the front-to-rear direction of the lower electrode;
a spacer layer, made of polymer, disposed between the upper electrode layer and the lower electrode layer, the spacer layer being provided at a corresponding position surrounding the upper electrode and the signal transmission line of the upper electrode layer and having an opening, through which the upper electrode and the lower electrode face each other without blocking of the spacer; and
a bump layer, made of polymer, disposed on the upper electrode layer and having a bump at its center.

Abstract
Disclosed herein are an electrode layer for capacitors, a method of manufacturing the electrode layer, a unit sensor using the electrode layer, and a tactile sensor using the unit sensor. The electrode layer comprises a polymer substrate, an electrode formed on the polymer substrate, and a signal transmission line formed on the polymer substrate such that the signal transmission line is connected to the electrode. The unit sensor comprises upper and lower electrode layers, which are identical to the above-described electrode, and a spacer layer made of polymer. According to the present invention, the sensor can be easily manufactured while the sensor has high flexibility and easy extensionabilty.
