1. A transparent electrochemical sensor for determining the concentration of a gas at or near biological surfaces comprising:
- a transparent support base;
a connecting strip comprising a plurality of respective leads attached to an edge of said base;
a plurality of sensing electrodes, each of 20μ
to 100μ
diameter, arrayed on a surface of said support base at a spacing of 40μ
to 200μ
for simultaneously sensing said gas at different regions at or near said biological surface, each of said sensing electrode being independently connected to a respective one of said leads and electrically insulated from all of the others of said sensing electrodes;
a reference electrode on said surfce and connected to a respective one of said leads;
a counter electrode on said surface and connected to a respective one of said leads; and
an electrolyte solution on said surface and in contact with said sensing electrodes, said reference electrode and said counter electrode.
