Abstract: An implantable micro-biosensor a substrate, a first electrode, a second electrode, a third electrode, and a chemical reagent layer. The first electrode is disposed on the substrate and used as a counter electrode. The second electrode is disposed on the substrate and spaced apart from the first electrode. The third electrode is disposed on the substrate and used as a working electrode. The chemical reagent layer at least covers a sensing section of the third electrode so as to permit the third electrode to selectively cooperate with the first electrode or the first and second electrodes to measure a physiological signal in response to the physiological parameter of the analyte.

Abstract: The present disclosure is generally related to 3D imaging capable OLED displays. A light field display comprises an array of 3D light field pixels, each of which comprises an array of corrugated OLED pixels, a metasurface layer disposed adjacent to the array of 3D light field pixels, and a plurality of median layers disposed between the metasurface layer and the corrugated OLED pixels. Each of the corrugated OLED pixels comprises primary or non-primary color subpixels, and produces a different view of an image through the median layers to the metasurface to form a 3D image. The corrugated OLED pixels combined with a cavity effect reduce a divergence of emitted light to enable effective beam direction manipulation by the metasurface. The metasurface having a higher refractive index and a smaller filling factor enables the deflection and direction of the emitted light from the corrugated OLED pixels to be well controlled.

Abstract: The present invention provides a micro biosensor for reducing a measurement interference when measuring a target analyte in the biofluid, including: a substrate; a first working electrode configured on the surface, and including a first sensing section; a second working electrode configured on the surface, and including a second sensing section which is configured adjacent to at least one side of the first sensing section; and a chemical reagent covered on at least a portion of the first sensing section for reacting with the target analyte to produce a resultant. When the first working electrode is driven by a first working voltage, the first sensing section measures a physiological signal with respect to the target analyte. When the second working electrode is driven by a second working voltage, the second conductive material can directly consume the interferant so as to continuously reduce the measurement inference of the physiological signal.

Abstract: An electro-tactile panel (ETP) apparatus for a display panel is disclosed. The ETP apparatus is composed of three major parts: a controller, a panel, and a holder. The panel consists of four layer made of transparent material. The first layer is an insulating substrate, the second layer is a conductive layer formed of a plurality of horizontal electrodes on the first layer. The third layer is an insulating layer having holes formed therein, which corresponding to the electrodes on the second layer. The fourth layer is a conductive layer formed of a plurality of vertical electrodes on the third layer. The panel is attached to the display panel by means of the holder apparatus. The electro-tactile signal and cursor position is process by the controller when the skin touches the panel so that some positions of the vertical electrodes and horizontal electrodes are electrically connected through the holes.

Abstract: This application relates to an electrotactile system and method for delivering tactile stimuli to a skin surface of a user. The system includes one or more electrotactile modules each comprising an array of electrodes electrically connected to an integrated circuit. Each integrated circuit has data processing and current driving capability. The current delivered from the integrated circuit to each electrode is relatively small, preferably less than 4 milliamps. The modules may be connected to a flexible PC board by spring-loaded connectors. In one embodiment a plurality of electrotactile modules may be grouped together to from an electrotactile device. Multiple electrotactile devices may in turn be deployed as part of a wearable article for use in virtual reality, telepresence, telerrobotics or other haptic feedback applications. The system is capable receiving and transmitting tactile data via a communication link, such as a conventional data network.

Abstract: A display apparatus and a method for distributed modules of light-emitting elements, the display apparatus comprising: a plurality of display modules, each comprising: a plurality of total passive clusters, an active control module and an electrical structure module. The total passive clusters and the active control module are attached onto the tube-shaped electrical structure module on one side or both sides. The electrical structure module comprises an interface for data and power transmission between the total passive clusters, the active control module and the electrical structure module such that a display apparatus for distributed modules of light-emitting elements is formed. Since easy assembly, setup, removal, maintenance, re-use, adjustment in display size, excellent display size/weight ratio and both single-sided and double-sided display can be achieved, the display apparatus is suitable for use in temporary display sites.
