ELECTRODE LAYOUT FOR BLOOD TEST SENSOR STRIP

摘要

An improved electrode layout for a continuous strip sensor is provided which reduces misalignment of the electrodes with the contacts which read the position of the strip. Better contact with the electrodes reduces or eliminates transient signals between stop positions of the sensor strip.

主权项

1. An elongated sensor strip for use in a blood sample test device, comprising:
a plurality of test sites arranged in series in a travel direction on the strip, wherein each test site includes a lancet hole, electrodes for determining a blood sample volume, and test electrodes for determining a blood sample characteristic; each test site comprising a non conductive substrate layer; a conductive layer on the substrate layer forming conductive pads defined by non-conductive lines and aligned with device contacts in the blood sample test device and; and a non-conductive layer superposed on the conductive layer having a window exposing a plurality of the conductive pads.
