Abstract Embedding viscous fluids in soft elastic metamaterials offers transformative potential for engineering applications, particularly vibration control and acoustic filtering. Despite this promise, effectively leveraging fluid viscosity to achieve low‐frequency, high‐quality bandgaps remains a significant challenge. Specifically, shifts local resonance modes lower frequencies while mitigating negative dynamic effective properties, resulting smoother transmission spectra. By incorporating liquids as resonant units, it is demonstrated how vibrational coupling dissipation can be harnessed engineer superior bandgap properties. The characteristics of locally with liquid fillings are systematically investigated through theoretical analysis, numerical simulations, experimental validation. shifted by up 5.6% within the concerned range, accompanied 4.1% bandwidth expansion. This overturns conventional notion that reduces system performance, showcasing its positive impact on bandgaps. work redefines dissipation, usually considered limitation, key enabler achieving broadband, high‐performance low‐frequency bandgaps, unlocking new possibilities advanced isolation technologies.
