Transducers


What are they?

Chemical Transducers are Integrated devices based on microelectronic technology with the capacity to translate chemical information in a processable signal of electrical or optical nature.

The operation of the transducers is based on the activity of 2 distinct areas of the device:

  • Receptor: Recognition element that interacts selectively with the substance we want to detect.
  • Transducer: Chip that translates the interaction between substance and receptor into an electrical or optical processable signal.

The use of chemical transducers is an emerging technique to measurement of chemical parameters due to the capacity to incorporate the advantages of microelectronics technology to detection methods (new or existing).

Advantages of microelectronic technology

  • High reliability
  • Quick response
  • Reduced size
  • Robustness and solid state nature
  • Massive fabrication  at low cost
  • Reproducibility

¿What types of sensors do we developed?

  • Potentiometric (ISFET): Selective to different analytes, ionic and molecular.
  • Amperometric: Detection of molecular species, COD, biochemical reactions (biosensors) and potential redox.
  • Impedimetric: Conductivity and complex impedance measurement for chemical and biosensors development.
  • Optics
  • Multi-sensors: Integrated transducers (electrochemical, optical, temperature) that combine the capacity of  different individual sensors  in a single chip.

To facilitate the use of sensors we develop the required electronic instrumentation
