Title: THz Based Hygrometer

Abstract: Due to the unique properties of Terahertz (THz) radiation, THz Spectroscopy is considered to be a cutting-edge method for detection of water vapour. In this project, I will be looking at fundamental rotational mode of water vapour at 0.557 THz in contrast to most optical hygrometers that are based on overtones in the IR region.

We aim to develop a prototype for the application in non-invasive ventilation (NIV) devices/ non invasive mask therapies for the patients with respiratory failures.

This talk will discuss the design of the THz based Hygrometer, which will be more sensitive and cost-effective than existing models and able to monitor in real-time.

We also discuss the efficiency/application of high electron mobility transistors (HEMTs) as cost-effective chips for THz detectors.
