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.
