← ScienceWhich risk increases when a microfluidic pump's actuator frequency resonates with channel geometry?
A)Increased analytical bandwidth
B)Increased mass transport rates
C)Fluidic channel wall cavitation✓
D)Minimized electrical impedance
💡 Explanation
Resonance causes standing waves; the increased energy implodes bubbles due to cavitation effects. Because channel acoustic impedance matching concentrates energy; therefore, energy cavitation damages surfaces, rather than bandwidth increases at specific frequencies.
