Abstract:
A micro-electrode array includes a substrate of a flexible material and one or more fine electrodes which are located on the substrate. The substrate includes a pattern which is located in a part of the substrate and reduces the thickness of the substrate by at least partly removing the substrate. A fine electrode array manufactured on a two dimensional plane is easily deformable into a three dimensional shape by the pattern which increases the flexibility of the substrate. For instance, the fine electrode array touches an object having a curved surface, thereby providing uniform contact according to the shape of an object when the fine electrode is inserted into a human body.

Abstract:
PURPOSE: An artificial retina system and a manufacturing method thereof are provided to obtain visual information and to stimulate the retina. CONSTITUTION: An artificial retina system comprises a substrate(300), a nanowire optical detector(301), a microelectrode array(302), and a power source(303). The substrate is patterned by lithographic processing. The nanowire optical detector comprises a nanowire in which resistance changes according to applied light. The microelectrode array stimulates retina cells and is placed to contact the retina cells. The power source supplies power for stimulating the retina cells to the nanowire optical detector and microelectrode array.
Abstract:
PURPOSE: A drug delivery system containing a layer structure with drug layers and polymer layers alternatively laminated is provided to highly maintain drug concentration of a target site and to easily control drug release rate. CONSTITUTION: A drug delivery system comprises: a core of a layer structure containing drug layers(110) and polymer layers(111) which are alternatively laminated; and a polymer outer layer(100) which surround the core and comprises an opening part. The drug delivery system further comprises a polymer cover(120) for covering the opening part. The structure inside the core has 2-10 layers. The polymer of the outer layer contains poly-caprolactone(PCL) or L-poly-lactide(LPLA).

Abstract:
PURPOSE: A vision tracking system using a driving command and a method thereof are provided to keep a directional point of a vision sensor of a mobile robot toward a target constantly even if the mobile robot moves linearly or rotates. CONSTITUTION: A vision tracking system comprises first and second driving units(20,40) and a controller(30). The first driving unit let a first body drive according to driving commands. The controller generates control signals for driving a second body corresponding to a motion of the first body by using the driving command. The second driving unit is connected between the first and second bodies and let the second body drive according to the control signal.
Abstract:
PURPOSE: Radar for a vehicle and the directional control system of a vision system are provided to control the oriented direction of a vision system and a radar system to a desired direction in consideration of the intention of an operator or an environment. CONSTITUTION: An inertia sensor system(110) and a handle steering angle sensor system(120) sense the posture and motion of a vehicle. A first driving part(140) and a second driving part(150) are driven by a control part(130). A radar system(160) and a vision system(170) are respectively connected to the first driving part and the second driving part. The oriented direction of the vision system and the radar system is changed by driving the first driving part and the second driving part. The radar system and the vision system collect information about vehicle traveling.
