Provided is a pressure sensor for electronic skin. The pressure sensor measures pressure levels, and includes conductive rubber, electrodes, and elastic rubber. The conductive rubber has conductivity that increases when a pressure exceeding a predetermined pressure is applied thereto. The electrodes are formed on either side surface of the conductive rubber to measure current flowing through the conductive rubber. The elastic rubber is formed on a top surface of one of the electrodes to disperse pressure applied to the conductive rubber.

Pressure sensor for electronic skin and fabrication method of pressure sensor for electronic skin

An organic micro-cavity lasers which can reduce an optical loss and derive the lasing by the electrical pumping is disclosed. The laser of the present invention has a bottom mirror layer formed on a substrate, a bottom electrode formed on the bottom mirror layer, an active layer formed on the bottom electrode, a top electrode formed on a peripheral portion of the active layer and a top mirror layer formed on the active layer except the peripheral portion. Therefore, the laser of the present invention can greatly reduce the optical loss since it has the bottom mirror layer, the active layer and the top mirror layer. Also, the injection of current can sufficiently accomplished because the top electrode having a ring shape is formed at the peripheral portion of the active layer so as to inject the current to the active layer.
