A biosensor is provided in accordance with the present invention. The biosensor includes an electrode support substrate, electrodes positioned on the electrode support, each electrode including a meter-contact portion and a measurement portion, and a sensor support substrate. The sensor support substrate cooperates with the electrode support substrate to define channel in alignment with the measurement portion of the electrodes. Additionally, the sensor support substrate includes opposite ends and at least one window. The at least one window is spaced-apart from the ends and in alignment with the meter-contact portion of at least one of the electrodes.
1. A method of forming a biosensor, the method comprising the steps of:
forming electrodes on a first surface of an electrode support substrate, each electrode including a meter-contact portion and a measurement portion,
forming a sensor support substrate having opposite ends and at least one window spaced apart from the opposite ends,
coupling the sensor support and the electrode support substrate together so that the at least one window is aligned with the meter-contact portion of the electrodes, and
applying a reagent to the measurement portion of the electrodes,
wherein a greater number of windows are formed on the electrode support substrate as are electrodes formed on the electrode support substrate.
2. The method of claim 1 further comprising the step of forming electrodes on a second surface of the electrode support substrate.
3. The method of claim 2 further comprising the steps of forming a second sensor support substrate and coupling the second sensor support substrate to the second surface of the electrode support substrate.
4. The method of claim 1 wherein the electrodes are formed on the electrode support substrate with a laser.
5. The method of claim 1 further comprising forming an opening in the sensor support substrate and the coupling step includes aligning the opening with the measurement portion of the electrodes.
