Operation of the proposed solution

Research focuses on the design and development of sensors and measurement systems tailored for healthcare, environmental monitoring, and cultural heritage preservation. Sensors developed are characterized to operate over a wide range of frequencies, from a few MHz to the microwave range. Research on resonant sensors, including Bulk Acoustic Wave (BAW) and Surface Acoustic Wave (SAW) sensors, is underway. Emphasis is being placed on microwave resonant sensors, which are inherently compatible with wireless technology and provide non-contact, accurate measurements. These sensors are being fabricated using various techniques, including inkjet printing, and tested under critical conditions, including cryogenic temperatures. Additionally, the research includes the characterization of electronic devices up to 70 GHz to ensure their performance in high-frequency applications.

Challenges

1) Addressing and compensating for environmental conditions like temperature, humidity, and pressure that can affect measurements.
2) Enhancing the reproducibility of devices developed using inkjet printing technology.
3) Ensuring long-term stability and reliability of sensors in varying environmental conditions.
