Postdoctoral Researcher Wideband Dielectric Sensor Design for Bacteria and Bio-particle Detection

What you will do

The dielectric property of biological cells and bacteria over a wide frequency range can be used to analysis their biological property and screen them from other normal cells in the blood. Unlike the conventional optical approach, this electrical approach leverages the rapid development in the semiconductor industry and enables many low-cost and real-time point-of-care applications. An example could be early cancer detection. There are several challenges in developing such devices. First, the dielectric sensor measures dielectric property over wide frequency range from MHz up to GHz (> 3 octaves), so the sensor needs to generate and process such broadband signal with low distortion.
Second, the dielectric sensor needs to analyze the particles or bacteria in a liquid with very low concentration (e.g., 1 cell/100mL). As a result, the noise floor of the sensor needs to be low.
Finally, to achieve optimum sensor performance, the dielectric sensor and the microfluidic device (a micro flow channel) need to be carefully integrated. So advanced packaging and assembly technologies should be explored.
In this postdoctoral researcher position, you will work with other experts in life science and sensor teams in imec to explore and develop this cutting-edge technology.As our postdoctoral researcher on wideband dielectric sensor design for bacteria and bio-particle detection you will:

  • Work with imec life science and sensor teams to explore the targeted applications and define the requirements for the wideband dielectric sensor. 
  • Benchmark different technologies and proposed a new method for the targeted applications.
  • Design a prototype with off-the-shelf devices to proof the concept of the new method.
  • Based on the prototype, provide requirements of the key components, e.g., ICs, microfluidic, electrodes. 
  • Be involved in the development of the key components using imec technologies.
  • Design and integrate the complete wideband dielectric sensor system.
  • Test the dielectric sensor in the real applications, together with imec life science and sensor teams.
