Electrochemical cells for amperomeric measurements

This type of transducer consists of a structure of three electrodes and can be deployed for amperometric measurements and cyclic voltammetry. To make the current flow, at least two electrodes are needed: a working electrode (anode) and a counter electrode (cathode). This enables measurement of the current and the cell tension, but not the electrode potential of the working electrode, determining the electrode reaction. For this measurement a third electrode is necessary; a reference electrode which is operated without current.


Electrode structure (WE, CE, RE) circular
Diameter of the working electrode (WE) 10 – 3000 µm
Chip surface area 4,5 x 4,5 mm
Material Gold electrodes on glass  
Reference electrode (RE) Possibility to print Ag/AgCl
Passivation Polyimid at need
Integrated temperature sensor (WE 500µm) Resistance (RT upto 150°C) 
Integrated heater upto 150°C 
Coating At customer request
