Projectdetails

Introduction

Monitoring gases and particles through the use of smart sensors has a crucial role in a wide range of applications, from environmental control to breath analysis for diagnostics. With the information provided by these sensors, we are able to predict, prevent, and act in potentially dangerous situations.

Requirements for Gas Sensors

In order for the data to be effectively transferred, the gas sensors must be integrated into portable devices with wireless connectivity, and must be miniaturized concurrently. To meet this requirement, the sensors must possess:

  • High sensitivity
  • Selectivity
  • Speed
  • Ultra-low power consumption
  • Compatibility with silicon technology

However, currently no existing technology on the market fulfills all of these criteria.

Project Overview

POLARSENSE aims to develop an optical (infrared) gas sensor demonstrator chip based on a novel graphene electro-polaritonic platform that is designed to address all of the aforementioned technical and commercial requirements.

Functionality and Performance

This will be demonstrated through its functionality and performance, with the capability of detecting multiple gases in a scalable, CMOS compatible system with a sensitivity of 0.1 ppm. The system will include specific optically active elements and an electrical detector all integrated within one single device.

The result is a highly compact and efficient sensing platform that does not require an external photodetector.

Development Process

To achieve this, POLARSENSE will:

  1. Simulate the demonstrator chip
  2. Design the chip according to specifications of our industrial partners
  3. Fabricate the demonstrator chip
  4. Test with a compact interferometer with a broadband infrared source to evaluate performance

Validation of Sensing Performance

We will then validate the sensing performance of the demonstrator system with acetone gas in a matrix containing different concentrations of ethanol and/or water vapor that are typically present in breath analyzer and environmental monitoring applications.
