The present disclosure relates to a stirrup having an opening and closing function for preventing a body from being injured in a situation such as falling from a horse. The present disclosure provides a stirrup having an opening and closing function, which is coupled to a saddle so that a rider's foot rests thereon, the stirrup including: a main body part having a bottom portion for placing a foot thereon, a top part connected to a saddle strap, and an open part formed on one side thereof; and an opening and closing part for opening and closing the open part, wherein the opening and closing part has one end connected to the main body part with a wire, and the other end which is attachable to and detachable from the main body part by means of magnetic force.

Stirrup with opening and closing function

A semiconductor device includes gate electrodes and interlayer insulating layers that are alternately stacked on a substrate, channel structures spaced apart from each other in a first direction and extending vertically through the gate electrodes and the interlayer insulating layers to the substrate, and a first separation region extending vertically through the gate electrodes and the interlayer insulating layers. Each gate electrode includes a first conductive layer and a second conductive layer, the first conductive layer disposed between the second conductive layer and each of two adjacent interlayer insulating layers. In a first region, between an outermost channel structure and the first separation region, of each gate electrode, the first conductive layer has a decreasing thickness toward the first separation region and the second conductive layer has an increasing thickness toward the first separation region.

The present disclosure enables materials of a triboelectric charging member to exhibit a characteristic of increased surface charge density, thereby improving output of a triboelectric generating device. Accordingly, the present disclosure provides a triboelectric generating device showing improved output without increasing a size of the triboelectric generating device or without increasing amounts of materials required for the triboelectric generating device. An embodiment of a triboelectric generating device provided according to a first aspect of the present disclosure includes a first electrode; a first charging layer formed on the first electrode; and a second electrode disposed on the first charging layer, wherein the first charging layer and the second electrode are arranged such that an interface between the first charging layer and the second electrode forms a frictional interface, and the first charging layer includes a ferroelectric polymer matrix and ferroelectric inorganic particles dispersed in the ferroelectric polymer matrix.
