Abstract: A functional patch for use with a contact lens includes an attaching layer and a functional patterned layer. The contact lens and the attaching layer are made of different hydrophilic materials to present two net-like structures respectively contain a plurality of first pores and second pores, and the second pores have pore size smaller than that of the first pores. The attaching layer is adsorbable to and detachable from the contact lens. A part of the functional patterned layer permeates into the second pores and the remaining part of the functional patterned layer is cured on the surface of the attaching layer. The attaching layer has closely arranged molecular chain blocks to form net-like structure having relatively small pore size. Therefore, only a limited amount of the material molecules of the functional patterned layer is permeated into the second pores, allowing the functional patterned layer to have a smooth surface.

Abstract: A memory structure including a substrate, charge storage layers, and a gate is provided. The charge storage layers are located on the substrate. The gate is located on the substrate on one side of the charge storage layers. The gate extends along a first direction. The gate has a protruding portion protruding along a second direction. The second direction intersects the first direction. The protruding portion is located between two adjacent charge storage layers arranged along the first direction.

Abstract: An optical identification record system is provided that combines physical record with digital music. The optical identification record system includes a record and a record player. The surface of the record is printed with optical identification codes. The record player includes a turntable, a first motor, a tone arm, a processor, a memory, and a second motor. The turntable of the record player is used to rotate the record. The tone arm includes a cartridge that reads the optical identification codes on the surface of the record to decode a corresponding audio file for playing.
