Current Research Projects

Kaya Lab focuses on multi-disciplinary research on developing sensors for biological and environmental applications. The research includes the modeling and characterization of advanced materials as well as the design and implementation of microelectronic sensor circuits. Kaya Research group will also collaborate with other disciplines to help drug development research on microfluidic devices.

Current projects include the following:

  • Modeling and Characterization of Advanced Materials for Biological and Environmental Monitoring. Biological and environmental monitoring can be more practical if appropriate materials are used. Piezoelectric materials, such as PZT and PVDF, not only link the vibration energy to electrical energy but also generate sensor data that can be processed with circuitry. Therefore, simulation and modeling of new piezoelectric materials will be main research topics for this project. Synthesis, fabrication and testing will also be involved.
  • Microfluidics for Biomedical Studies. Microfluidic devices, in general, can be used for isolation and manipulation of the cells and they are capable of precisely controlled fluid flow, generating dynamically controlled temporal and spatial gradients, and compartmental cultures. Microfluidic fabrication techniques, such as soft lithography, will be used to create chambers to study various diseases on lab-on-a-chip devices.
  • Design and Implementation of Microelectronic Sensor Circuits. This project aims to develop energy efficient CMOS sensor circuits. In this context, low-energy circuit design techniques will be explored. Power conditioning interface circuits, data converters and temperature sensor systems will be the main elements. Wireless communication of each sensor node will also be studied.
