An electrochemical sensing apparatus and methods are provided. In one embodiment, an apparatus is provided having a carrier that supports an electrochemical module and that communicates between electrodes on the electrochemical module and an analyte measurement device.

Electrochemical sensors with carrier field

Electrochemical sensors for investigating a physiological sample and methods of manufacture are disclosed. The sensor includes a longitudinally extending reaction cell, having electrodes and a reagent, and laterally spaced electrical contact points for electrically communication with a meter. An array of such sensors is further disclosed including connective flaps for joining adjacent sensors. In use, the array of sensors can be stored in a folded configuration and dispensed individually.

Method and apparatus for electrochemical analysis

Electrochemical sensors for investigating a physiological sample and methods of manufacture are disclosed. The sensor includes an electrochemical reaction cell, having electrodes and a reagent, and laterally spaced electrical contact points for electrically communication with a meter. Further described herein is a multi-chambered sensor having an electrochemical reaction cell and an immunological cell. The multi-chambered cell can also include a pre-chamber.

A microfluidic device for transferring liquid from a first chamber to a second chamber is provided. The device has a first chamber; a second chamber; and a barrier between the first chamber and the second chamber, the barrier having least one opening fluidly connecting the first chamber to the second chamber, the at least one opening being sized such that a retention force, such as surface tension, keeps the liquid in the first chamber. The fluid is transferred from the first chamber to the second chamber when an initiation input such as fluid pressure is introduced to the liquid that is sufficient to overcome the retention force. The device may be a sensor strip.

Fluid transfer mechanism

The present invention relates to electrochemical cells including a connector which mates with a connection device to provide electrical connection to meter circuitry.

Electrochemical cell connector

A strip ejection system for holding and ejecting a strip is provided. The system includes a body and a strip movement section. The strip moving section includes all elements of the system that are involved with moving the strip, including a pressing element for pressing against the strip to move the strip from a first position to a second position. The pressing element is the only element of the strip movement section that is movable relative to the body.

Strip ejection system

There is disclosed a method of measuring formation of a barrier to restrict or reduce movement of an electroactive species. The method comprises providing an electrochemical cell having a working electrode and a counter electrode spaced from the working electrode, providing a subject component, a testing component and at least one electroactive species within the cell, the subject and testing components being intended to cause the formation of a barrier to restrict or reduce movement of an electroactive species, applying a potential between the working electrode and the counter electrode sufficient to produce a current proportional to the concentration of the electroactive species being measured, and measuring the current at the working electrode to obtain a measure of the formation of the barrier to restrict or reduce movement of the electroactive species.

Methods of measuring barrier formation

The invention relates to a sensor adapted for electrical connection to a power source having an electrical contact means (). The sensor has a first insulating substrate () carrying a first electrode () and a second insulating substrate () carrying a second electrode (). The electrodes are disposed to face each other in spaced apart relationship, sandwiching a spacer () therebetween. A first cut-out portion extends through the first insulating substrate () and a spacer () to expose a first contact area () on the second insulating substrate (). This permits the electrical contact means () to effect electrical connection with the first contact () which in turn is in electrically conductive connection with the second electrode (). A similar contact arrangement may be disposed on the opposite side of the sensor.

Sensor connection means

A method of forming an electrical connection between an electrochemical cell and a meter is provided. According to the method, an electrical connection is made between a meter, by means of a wedge-shaped connector with upper and lower conductive surfaces, and an electrochemical cell comprising a first substrate with a first electrically conductive coating and a second substrate with a second electrically conductive coating, the electrically conductive coatings being disposed to face each other in a spaced apart relationship by an insulating spacer. The meter further includes a pivot point for rotating the wedge connector on the pivot point.
