MEMS ARRAY SYSTEM AND METHOD OF MANIPULATING OBJECTS
A micro-electro-mechanical systems (MEMS) array system is configured to apply suction forces for the manipulation of objects. The MEMS system includes includes a two-dimensional MEMS array of a plurality of individual MEMS elements. Each MEMS element comprises: a casing structure; a flexible membrane attached to the casing structure; and an electrode structure, wherein a voltage applied to the electrode structure actuates the MEMS element to cause the flexible membrane to flex relative to the casing structure. The flexible membrane and the casing structure define a gap into which the flexible membrane may flex, and a foot extends from the flexible membrane in a direction away from the casing structure, wherein the foot and the flexible membrane define a clearance region on an opposite side of the flexible membrane from the gap. When the MEMS element interacts with an object to be manipulated the foot spaces the membrane apart from the object. The MEMS array system further includes a control circuit that selectively actuates one or more of the MEMS elements of the MEMS array.
MEMS DEVICE AND MANIPULATION METHOD FOR MICRO-OBJECTS
A micro-electro-mechanical systems (MEMS) includes a flexible membrane that creates a suction force by flexing to permit manipulation of a microscale object. The MEMS element includes a casing structure; a flexible membrane attached to the casing structure; and an electrode structure, wherein a voltage applied to the electrode structure causes the flexible membrane to flex relative to the casing structure. The flexible membrane and the casing structure define a gap into which the flexible membrane may flex, and a foot extending from the flexible membrane in a direction away from the casing structure, wherein the foot and the flexible membrane define a clearance region on an opposite side of the flexible membrane from the gap. When the MEMS element interacts with an object to be manipulated the foot spaces the membrane apart from the object, and flexing of the membrane generates the suction force for manipulating the object.
