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 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 exemplary zoom ratio adjusting switch includes a panel, a rotary member and a spring. The panel defines first and second grooves whose innermost extremities are on a circumference of a circle. Each groove includes a wide part and a narrow part. The rotary member includes a body positioned to a top side of the panel and first and second locking legs extending from the body. The first and second locking legs extend though the wide parts and slide in the narrow parts respectively. Feet extend from the locking legs respectively at the bottom side of the panel and are restrained at the bottom side of the panel. The spring is positioned to the bottom side of the panel and restrains travel of the first locking leg from the narrow part to the wide part of the first groove.
