device

[Sam Rice]

Hi all users;
I designed a simple sensor as shown in attached file,I don't want to have gas molecules  in my electrodes but because my substrate is small they repeat in electrodes, unfortunately I can not change my dimensions and also I need to have device with 3 gas, do you have any solution ?

Unfortunately, there is no easy trick. You should make the device larger, so that the electrode repetitions are without gas molecules.
May I ask you why you can't increase the length of your device?
