Research Projects

Title: Investigation into Piezo-photoelectric Coupling in ZnO Nanostructures and Acoustic Wave Resonators: Towards Devising Room-temperature Organic Vapour Sensors

The project involves fabrication of composite volatile organic compound (VOC) sensors, based on ZnO nanostructures and thickness shear mode acoustic resonators. This project aims to investigate the influence of combined effect of piezoelectricity and photoelectricity when ZnO based resonant sensor is exposed to both UV and VOC. Under UV illumination, ZnO based resonant sensors undergo shift in resonant frequency due to acousto-electric interactions. When exposed to VOC, this acousto-electric interaction can help improve the sensitivity of the sensor as well as reduce the temperature threshold for VOC sensors.

Title: Quartz crystal microbalance (QCM) based wearable UV sensor

This project aims to develop a wearable UV sensor prototype for real-time UV index monitoring. Ultraviolet (UV) radiation is a proven human carcinogen. Long-term UV exposure has proven to be the root cause for various skin problems as well as non-melanoma skin cancer. Thus, it is important to have a real-time monitoring of UV exposure in order to take preventive measures. This project focuses on utilization of proven UV sensing materials and highly reliable resonant devices to fabricate UV sensor system and sensor interface electronics.
