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
Benefits of making electrochemical sensors with P-Flex®PET

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.

Measured by W:Au C:Au R:Ag /AgC electrodes with PGSATAT204 P-Flex made by Metrohm Ltd.

Sensors to measure thickness of target molecule based on Oxidation-Reduction Potential(ORP).
A sensor has two gold electrodes and one Ag-AgCl electrodes.

About P-Flex®

P-Flex® is a single-face flex PCB manufactured using the Pure Additive™ method. Conventionally, electronic circuits have been manufactured by applying a method known as lithography, in which a thin metallic sheet is first applied to the board surface, and then unrequired sections are melted away.


The Pure Additive™ method (*) developed by Elephantech is a concept completely opposite to what had been used until now, using a proprietary manufacturing technology that prints metal nanoparticles with inkjet only on the necessary parts and grows metals by electroless plating technology.
(* Patent No. 6300213)

By reducing the amount of metal, liquid waste and man-hours, we can lessen manufacturing costs and shorten the lead time.
Elephantech will continue to reduce its environmental burden and contribute to the achievement of SDGs.

Stiffeners When specifying the thickness of the connector part, film stiffeners can be used to adapt to connectors of 200 µm or 300 µm in total thickness.
Component mounted parts and such can be adapted by using FR4 stiffeners of 0.1, 0.3, 0.5, 1.0, and 1.6mm in thickness.
Other stiffeners, electromagnetic wave shield film, double-sided tape and such are also available.
Inspection Visual inspection + opens/shorts test
