  • Publication number: 20240148280
    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.

  • Patent number: 11950902
    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.

  • Patent number: 8370989
    Abstract: Provided is a static eliminator with dust removal feature. The static eliminator includes an ion generator, a dust-removing main body and a dust-collecting device. The dust-removing main body has a workpiece-passing channel passing through the dust-removing main body. A dust-scraping member is disposed on a sidewall of the workpiece-passing channel. A blow vent of the ion generator communicates with said workpiece-passing channel and faces to the dust-scraping member. An inlet end of the dust-collecting device communicates with the workpiece-passing channel.

  • Publication number: 20120055970
    Abstract: An auto-breaking machine for breaking a base band from terminals of a connector includes a positioning assembly positioning the connector, a feeding assembly driving the positioning assembly to deliver the connector, and a breaking assembly including a motor, an adjusting part connected with the motor, a drive member fastened to the adjusting part and having a front defined as a drive post with an adjustable offset distance between the axis thereof and that of the motor, a slider slidably mounted to a support holder and defining a window having a height corresponding to the diameter of the drive post, and a breaking part fastened on the slider. The drive post is inserted in the window to drive the slider to slide up and down via the turn thereof and further drive the breaking part to move up and down so as to break off the base band from the terminals.

  • Publication number: 20120026513
    Abstract: Provided is a coplanarity-testing machine. The coplanarity-testing machine includes a working stage, an illuminant, an image picking-up processor, a frequency converter, a double-cross lines generator, a linear module and a display. The linear module includes a test vehicle, a linear drive mechanism and a regulating block. The linear drive mechanism can drive the test vehicle to linearly move to and fro on a bearing surface of the working stage. The regulating block is placed on a supporting surface of the test vehicle. By adjusting the double-cross lines generator, horizontal lines of the generator can coincide with a projecting line of the bottom surface of the regulating block, and vertical lines of the generator can measure the height of the regulating block. The coplanarity-testing machine can timely and exactly display the testing result, is easily operated, and has a high testing efficiency and a high exact degree of testing.
