Abstract: A crop harvesting apparatus includes a pressure generator configured to generate a pressure, a driver configured to have a shape that changes in response to receiving the pressure from the pressure generator, and a cutter configured to cut an object to be cut in accordance with a change in the shape of the driver.

Abstract: A pneumatic cutter with a concealed blade includes a pouch in which an inner space filled with air is formed and which includes a variable portion configured to, upon a pneumatic pressure being applied to an inner portion of the pouch, protrude outward as the inner space expands and, in a case where the pneumatic pressure is not applied to the inner portion of the pouch, be concavely recessed inward as the inner space contracts; and a blade installed at the variable portion and configured to, upon the variable portion protruding outward due to the pneumatic pressure being applied to the inner portion of the pouch, protrude toward an object to be cut and cut the object to be cut.

Abstract: A soft pneumatic module includes a first frame defining a first path portion, a second frame opposite to the first frame and defining a second path portion, a retainer connected to the first frame and the second frame, a plurality of first crease parts disposed along a circumference of the first frame at two sides of the retainer and obliquely disposed inward from the first frame, and a plurality of second crease parts connected to the plurality of first crease parts and the second frame, disposed along a circumference of the second frame at the two sides of the retainer, and expanded along with the plurality of first crease parts as a fluid is injected into the soft pneumatic module.

Abstract: An electrode including: a coating part coated with an electrode active material; and an electrode tab part provided on one side of the coating part, wherein the electrode tab part includes: a first electrode tab connected to the one side of the coating part; and a second electrode tab connected to the first electrode tab and bent in a direction of the first electrode tab to overlap one surface of the first electrode tab.
