What is an electrochemical sensor
What is an electrochemical sensor

An electrochemical sensor is a sensor that can figure out the status by using redox potential. It is used for the following cases;

  • for environmental and water quality analyses, measurement of the amount of copper, arsenic, and mercury and the like contained in the water.
  • for measurement of the blood glucose level, lactic acid, urine sugar sensor, and glutamic acid etc as a transducer part of a biosensor etc...

Benefits of making electrochemical sensors with P-Flex®PET
electrochemical-sensors-en

Usually, the electrochemical sensor is manufactured only by silk screen printing. However, when it is combined with the 3 μm copper wiring of P-Flex® PET;

  • Reduction of wiring resistance value.
  • Cost benefit compared to gold paste printing by making gold electrode with gold flash.
  • Because it is a PET base that doesn't absorb water, it can reduce water absorption induced sensor sensitivity trouble, can also be used for flow cell and such.
  • Can be produced in small batches.
  • Production price is negotiable.

For the prototypes, we plan to provide a one-stop service with paste spreading instead of part mounting for roughly the same price.
