Provided are a structure of an automobile electronic key for security and a method for performing the function thereof. It is determined whether at least one of a driver seat door closing signal and a brake pedal signal is on. A key fob of an automobile is requested to send the ID thereof, and the ID is received from the key fob when at least one of the driver seat door closing signal and the brake pedal signal is on. The key fob is authenticated using the received ID. An actuator is driven to move a locking member such that a car key is switched to a rotatable state when the key fob passes authentication. The actuator is driven to move the locking member such that the car key is switched to an unrotatable state when the key fob does not pass authentication.

Structure of automobile electronic key for security and method for performing function thereof

The present invention provides an organic thin film transistor (OTFT) being operatable at a low-voltage. The OTFT has a gate dielectric layer of ultra-thin metal oxide or a dual gate dielectric layer of metal oxide and organic dielectric. The metal oxide layer is self-grown to a thickness lower than 10 nm by direct oxidation of a metal gate electrode in Oplasma process at a temperature lower than 100&#xb0; C. The gate electrode is deposited with pattern on a plastic or glass substrate. An organic semiconductor layer is deposited on the gate dielectric layer, and source/drain electrodes are formed thereon. In case the dual gate dielectric layer is used, the source/drain electrodes can be disposed under the organic semiconductor layer to realize a bottom contact structure.

Low-voltage organic thin film transistor and fabrication method thereof

A wallpaper having a thermochromic material layer and a manufacturing method thereof are disclosed where colors of a wallpaper having a thermochromic material layer change by a surrounding or human body temperature so information concerning surrounding temperature or human body health state is provided, and a user does not feel tedious about colors of a wallpaper. The manufacturing method of a wallpaper having a thermochromic material layer comprises forming a wallpaper substrate; forming at least one plane heater on the wallpaper substrate; forming at least one thermochromic material layer on the wallpaper substrate or the plane heater; forming at least one protection layer on the wallpaper substrate so that the thermochromic material layer and the plane heater are substantially covered; and forming a power supply and control means on the wallpaper substrate for supplying power to the plane heater and controlling temperature.
