Abstract: A drug delivery device and a method for manufacturing the same, and more specifically, a drug delivery device that can deliver a drug to a biological tissue while minimizing damage thereto and can come into close contact with the biological tissue to be able to measure an electrical signal of or apply electrical stimulation to the biological tissue and a method for manufacturing the drug delivery device are proposed. The drug delivery device includes a substrate unit that is inserted into a human body and has a porous insertion portion having one or more discharge voids. The insertion portion is provided to be deformable to match a shape of a biological tissue while expanding and contracting as a drug is injected into and discharged from an inside of the injection portion.

Abstract: A balloon type retinal stimulation device includes: a substrate unit having an insertion portion provided to be inserted into an eyeball; and a stimulation unit that is provided at one or both of one and the other surfaces of the substrate unit. The insertion portion is provided to be expandable and contractible as a fluid is injected into and discharged from an inside of the injection portion. When the insertion portion expands, one surface of the insertion portion is deformed to match a shape of the retina such that the stimulation unit is brought into close contact with the retina on which an image is formed, and the other surface of the insertion portion comes into close contact with an inner surface of the eyeball that is not a region of retina on which an image is formed, to support the insertion portion that is in contact with the region of retina on which an image is formed.

Abstract: The present invention provides a selective bonding method of polymer substrates. The present invention allows selective interfacial bonding between a polymer substrate and a parylene layer by using a mask pattern and plasma treatment, and enables the formation of a three-dimensional structure by injecting a fluid into a non-bonded area.
