Smart Modular Cosplay Armor
Overlapping pangolin-scale-inspired panels that harvest kinetic energy from convention walking to power micro-climate cooling. Venus flytrap-inspired vents automatically open based on body temperature and activity level.
A cosplayer in a full fur suit walks into a crowded convention hall and instead of overheating like everyone else, their costume's scales subtly ripple open, releasing cool mist exactly where they need it most - they're the only one fresh and comfortable after 6 hours of photos and panels.
