Waterproof Case for Mobile Phones
Waterproof phone cases face increasingly demanding requirements as devices grow more sophisticated. Current designs must maintain IP68 protection while accommodating multiple camera arrays, precise biometric sensors, and wireless charging—all while managing thermal loads that can exceed 40°C during intensive use. Testing shows that traditional gasket seals can degrade under these conditions, particularly around port openings and speaker membranes.
The fundamental challenge lies in maintaining complete water protection while preserving device functionality and thermal management across all usage scenarios.
This page brings together solutions from recent research—including advanced membrane acoustics, multi-stage sealing systems, pressure-equalizing vents, and thermal-aware case architectures. These and other approaches focus on practical implementations that balance protection with daily usability.
