| Abstract: | A paper-based micro-fluidic switch has been implemented using surface acoustic wave.It is comprised of a 127.68° yx-LiNbO3 substrate and two paper micro-channels within small spaces.An interdigital transducer with 27.5MHz center frequency and a reflector were fabricated on the piezoelectric substrate,and the paper micro-channels were stuck on the piezoelectric substrate by PDMS film.Micro-fluids could not pass through the small spaces of the two paper micro-channels without SAW,which is "off" of the switch.However,the micro-fluids could pass through the small spaces by the helping of SAW excited by the interdigital transducer,when an amplified RF signal is added on the interdigital transducer.The switch is in"on"state.Experiment results of red dye solutions and NaNO2 solutions show that paper micro-fluidic switch can be implemented by the helping of SAW. |
