Measuring Photonic Chips for E-Nose Development
One of the research lines within the Applied Nanotechnology group at Saxion University of Applied Sciences (Enschede) focuses on the development of gas sensors. One of the options we are exploring involves modifying photonic chips. By applying various polymers to these chips, we aim to make them sensitive to specific gases. These coated chips will eventually be used in the OBSeRVeD project, which focuses on the early detection of diseases in poultry houses.
By using various types of polymers (sensitive to different gases) on sensors/chips, we hope to develop an electronic nose (e-nose) selective for specific poultry diseases. The focus is particularly on detecting red mites. To assess the suitability, selectivity, and sensitivity of the coated photonic chips to specific gases, measurement series must be performed. This information is crucial for the e-nose development.
During this internship/graduation project, you will focus on coating and testing of the photonic chips. With an emphasis on developing measurement protocols and conducting measurement series on coated aMZIs (a specific type of extremely sensitive photonic chips).
- Coating: Initially, you will coat the aMZI chips using pre-established protocols with well-researched polymers.
- Testing and measurements: You will then perform measurement series using our Owlstone gas calibration system, capable of generating precise known concentrations of target gases such as ammonia or other gases present in poultry houses. Using the sensor signals, you will evaluate the chips sensitivity towards these gases.
Some of the ammonia measurements will be conducted in collaboration with another student. Your findings will be used by various project partners and will help us select suitable coated photonic chips for the e-nose!
In the OBSeRVeD project we have two open internship/graduation positions (also see “Sensors for Ammonia Detection in Poultry Houses”). Based on your background and interests, we can discuss which assignment suits you best.
