Microfluidically tuned components

This part of our work is focused on the use of fluid as a dielectric contact to tune passive electronic components as inductor and capacitor. By introducing the DI water in microchannels positioned between metallic electrodes, we obtain a significant tuning of their main characteristics ( value; insertion loss; quality factor)

 

1. Capacitors

The capacitance increases continuously between Cmin = 0.52 pF and Cmax = 18.5 pF. Hence, its  tuning range reaches 3460% at 500 MHz.
