A semiconductor device with a strain layer and a method of fabricating the semiconductor device with a strain layer that can reduce a loading effect are provided. The power supply device also includes a fuel cell unit including a negative electrode that is exposed to outside through the fuel introduction unit and that can contact with the fuel, the fuel cell unit being configured to generate electrical energy from the fuel; and an electronic controller unit configured to control feeding of the electrical energy to an external device. The at least one video camera obtains video streams, converts the video streams into USB-compatible signals, and transmits the USB-compatible signals to the computer via the USB line. The figures include central body portions from which flexible limbs and head extend and features that allow the figures to free stand and to hold objects.
