Printed electronics laboratory, including extensive screen and inkjet printing facilities
The Zepler Nanofabrication centre
Material characterization, SEM, and optical surface profiling kits

Multi-layered flexible circuits fabrication based on copper laminated and screen-printed low-temperature silver inks.
RF devices, antennas, and material characterization up to 50 GHz.
Multi-source energy harvesting and low-power sensor nodes
Extensive mechanical reliability testing of flexible and wearable circuits
