// UV DETECTION THAT ADAPTS LIKE A CHAMELEON
Solar-powered smart patches that change color to show real-time sun exposure.
No apps. No chemicals. Just instant visual feedback.
You're at an outdoor music festival dancing with friends. You glance at your wrist and see your patch has shifted from cool blue to warning orange. You realize you've had exactly 2 hours of sun and need to reapply sunscreen NOW—saving yourself from painful sunburn that would've ruined the rest of your weekend.
Colors shift from blue → cyan → yellow → orange → red based on cumulative UV exposure. No guessing. No apps needed.
Embedded micro-solar cells keep the patch active for 12+ hours. Zero batteries. Zero waste.
Water-resistant. Sweat-proof. Rugged design that survives mosh pits, pool parties, and everything in between.
That's $3 per patch. Cheaper than a single drink at the festival.
