A variable-focus liquid lens is provided. The liquid lens includes a membrane and a fluid. The membrane is made of a transparent elastomer, and the fluid fills a predetermined space to contact at least a lens surface of the membrane. The membrane and the fluid are respectively made of materials repulsive to each other, for example, hydrophilic and hydrophobic materials or oleophilic and oleophobic materials. Accordingly, a repulsive force between the fluid and the membrane can prevent the absorption or leaking of the fluid into/through the membrane.

A multilayered electroactive polymer (EAP) device and a method of manufacturing the same is provided. The multilayered EAP device includes a plurality of unit layers. Each unit layer includes an EAP layer formed of an electroactive polymer (EAP), a protecting layer configured to prevent a material from penetrating into the EAP layer, and an active electrode formed using a conductive material. The protecting layer may be formed below the active layer or above the active layer. The active electrode may be interposed between two protecting layers.

A fastening device for a low-profile fuses of vehicle, which can achieve simple and robust coupling of the low-profile fuse while enabling the fuse to be easily connected to or disconnected from a vehicular junction box, is disclosed. The fastening device serves to connect or disconnect the low-profile fuse to or from the junction box via upward/downward movement thereof while maintaining coupling between the low-profile fuse and the junction box, and includes a socket integrally formed at an upper surface of the junction box and having plug coupling recesses and a fuse connecting recess indented in the upper surface of the junction box, terminals being disposed inside the fuse connecting recess so as to be exposed to the outside, and a plug vertically movably coupled in the socket while being coupled laterally with the low-profile fuse to enable connection or disconnection between the low-profile fuse and the terminals.

A field effect transistor includes laterally spaced apart source and drain regions in a substrate, laterally spaced apart undoped regions in the substrate between the laterally spaced apart source and drain regions, a doped channel region in the substrate between the laterally spaced apart undoped regions, and a gate insulating layer on the substrate. A main gate is on the gate insulating layer opposite the channel, and first and second sub gates are on the gate insulating layer, a respective one of which is opposite a respective one of the spaced apart undoped regions. The first and second sub gates are laterally spaced apart from and electrically insulated from the main gate. The transistor may be formed by patterning a photoresist layer and a gate layer to form a main gate and first and second sub gates, reflowing the photoresist into the lateral space between the main gate and the first and second sub gates, etching the gate insulating layer using the reflowed photoresist as a mask, and implanting ions into the substrate to form source and drain regions using the etched gate insulating layer as a mask.
