Electrochemical sensor
First Claim
1. An electrochemical sensor for a liquid sample, the sensor comprising a substrate along which a liquid sample may travel by capillary action, said substrate being associated with an electrochemical detection arrangement and a power source therefor, wherein the power source comprises at least one pair of electrodes of dissimilar material provided on the substrate and arranged such that liquid sample will travel by capillary action between the pairs of electrodes of said at least one pair of electrodes causing a current to be generated by said power source for operating the electrochemical detection arrangement.
