Design and characterization of a passive, disposable wireless AC-electroosmotic lab-on-a-film for particle and fluid manipulation

摘要: Abstract A wirelessly powered and controlled biased-AC electroosmotic (biased-ACEO) lab-on-a-film (LOF) is presented here for particle fluid manipulation. Amplitude modulation (AM) inductive coupling are used wireless transmission of low frequency signals required excitation biased-ACEO effects employed by the LOF microfluidic functions. The consists a receiving coil (for inductively transmitted high signals), surface mounted devices recovering AC signal) an array interdigitated electrodes (IDE, effects). Unlike existing lab-on-a-chip that have cumbersome set-ups, require voltages perform only one function, has compact flexible structure, works at very voltage ranges, can several operations corresponding to wirelessly-controlled voltage. When level demodulated signal over IDE about 0.7 V, performs enrichment designated electrodes. functions as active mixer 2 V; pump when reaches 3 V. prototyped rapidly on substrate cost using inexpensive benchtop equipment with overall dimension 10 × 20 mm2. Though electrode definition limited micro-scales, prototype successfully demonstrated desired In addition signals, printed circuit board-based device offers effective solution small, systems in nontraditional clinical diagnostic tools, disposable heath care settings.
