Embossed cell analyte sensor and methods of manufacture

摘要

An analyte measurement system is provided having sensors with embossed test chamber channels. In one embodiment, the sensors are elongate test strips for in vitro testing, each test strip having a substrate, at least one electrode, an embossed channel in the electrode, and lidding tape covering at least a portion of the embossed channel. Methods of manufacture are also disclosed for filling the sensor channels with reagent, and for trimming the ends of the sensors to eliminate the need for a calibration code during use of the sensors with a meter.

主权项

1. A method of manufacturing a plurality of analyte sensor having similar operating characteristics, the method comprising:
forming a plurality of substantially functional analyte sensors, each sensor having a channel extending to an edge of the sensor; testing at least one of the sensors to determine a calibration parameter of the sensor; based on the calibration parameter of the tested sensor, trimming a predetermined amount from one or more of the edges of the non-tested sensors, thereby reducing a sample volume of the channels of the sensors and changing a calibration parameter of the sensors.
