摘要： A method for continual monitoring of a physiologic analyte in a subject includes steps of contacting the subject with a collection reservoir such that the analyte can move from the subject into the collection reservoir, the contents of the collection reservoir being in operative communication with a detector, collecting the analyte in the collection reservoir, using the detector to detect the analyte in the collection reservoir, and, once the analyte has been detected, rendering the analyte undetectable by the detector. Also, apparatus for continual monitoring of a physiologic analyte in a subject includes a collection reservoir for receiving the analyte from the subject, the contents of the collection reservoir being in operative relationship with a detector that detects the analyte in the reservoir, and means for rendering the analyte, once detected, undetectable by the reservoir.

摘要： A chemical signal-impermeable mask is positioned in the electrolyte flow such that the mask is between a source of chemical signal and a working electrode which senses the chemical signal transported from the source (e.g., by diffusion). The configuration of the mask is such that the mask prevents substantially all chemical signal transport from the chemical signal source having a radial vector component relative to a plane of the mask and the catalytic face of the working electrode, thus allowing primarily only chemical signal transport that is substantially perpendicular to the place of the mask and the catalytic surface of the working electrode. By reducing or eliminating chemical signal radial transport toward the working electrode, the mask thus significantly reduces or eliminates edge effects. By substantially reducing edge effects created by radial transport of chemical signal, it is possible to obtain a more accurate measurement of the amount (e.g., concentration) of chemical signal that is transported from a given area of source material.

摘要翻译：化学信号不可渗透的掩模位于电解质流中，使得掩模位于化学信号源和感测从源传输的化学信号（例如通过扩散）的工作电极之间。掩模的配置使得掩模基本上防止具有相对于掩模的平面和工作电极的催化面的径向矢量分量的化学信号源的所有化学信号传输，因此主要仅允许化学信号传输基本上垂直于掩模的位置和工作电极的催化表面。通过减少或消除朝向工作电极的化学信号径向传输，掩模因此显着地减少或消除了边缘效应。通过显着降低由化学信号的径向传输产生的边缘效应，可以获得从源材料的给定区域输送的化学信号的量（例如，浓度）的更准确的测量。

摘要： An electrode assembly for sensing an electrochemical signal diffused from a source to a working electrode which is comprised of a plurality of substantially separated working electrode surfaces is disclosed. The electrode of the invention is comprised of 1) a working electrode made up of a plurality of working electrode surfaces or components and 2) a electrically insulating gap defined by adjacent edges of 1) insulating the working electrode surfaces or components from each other. The working electrode components are configured to receive electrochemical signal from two or preferably three dimensions simultaneously. The working electrode components configured over the same surface as a single electrode provide (1) an improved signal to noise ratio as compared to a single electrode by reducing noise, and (2) provide an overall enhanced signal after sensing for a given period of time.

摘要： A method for measuring the concentration of a chemical present in a blood stream of a mammalian subject is disclosed. The method involves contacting the subject's skin with a sensor assembly comprised of an ionically conducting material which contacts the skin, a working electrode which is in contact with the ionically conducting material which electrode has a catalytic surface and a mask having an opening therein. The mask is positioned between the skin and the working electrode. When the electrode is activated, chemical is transported through the skin and the ionically conductive material. The mask is positioned so that it blocks the flow into the catalytic surface except for flow which is substantially axially to the catalytic surface. Electrical signal generated at the working electrode is monitored over a period of time and correlated with a concentration of chemical present in the blood stream of the mammalian subject. The mask reduces or eliminates chemical signal which can radially transport toward the working electrode thereby reducing or eliminating edge effects making it possible to obtain a more accurate measurement.
