Bioelectronics and Sensors

Bioelectronics connects semiconductor devices with biological and chemical systems. Our interests include sensing mechanisms, functional interfaces and the interplay between ionic and electronic transport.

Device fabrication and characterization help us understand how materials, architecture and operating conditions influence sensitivity, selectivity, stability and reliable signal acquisition.

Wearable Electronics

Wearable electronics brings sensing devices into contact with curved, moving surfaces. This subarea explores flexible materials, conformable interfaces and device architectures, with attention to mechanical reliability, signal quality and stable operation during use.

Printed Electronics

Printed electronics connects electronic materials with pattern-based fabrication. We examine how inks, substrates, processing and interfaces influence device uniformity, charge transport and sensing performance.

Molecular Electronics

At molecular scales, chemical structure and interfacial interactions can govern charge transport and electronic response. This subarea explores molecular and biomolecular materials as functional components of devices, linking their assembly and integration with sensing and electronic behaviour.

Terahertz Technologies

Semiconductor materials and device architectures underpin our work on terahertz detection and modulation. This direction examines how charge transport, electromagnetic coupling and device geometry shape the response to terahertz radiation, including integration with resonant structures and metasurfaces for sensing and wave control.
