Study Design and Objectives RCTD-031 appears structured as a multicenter, double-blind, randomized controlled trial comparing Device 031 plus standard care versus sham-device plus standard care. Primary objectives likely include demonstrating superiority on a clinically meaningful patient-reported outcome (e.g., pain score reduction or functional improvement) at a pre-specified endpoint (e.g., 12 weeks). Secondary objectives plausibly assess safety, durability of effect, quality of life, and objective functional measures. rctd-031
The ~70 % increase in net cooling power relative to RCTD‑020 stems mainly from the metasurface’s enhanced emissivity and reduced solar absorption. The high‑ZT TE legs (average ZT≈1.2 at 300 K) mitigate the typical efficiency loss at low ΔT, allowing a respectable conversion efficiency despite modest temperature differentials. Common Issues ------------- No LCD → Check power
The topmost layer comprises a (periodicity 1.2 µm) tuned to exhibit near‑unity emissivity (> 0.98) across the 8–13 µm band while reflecting solar wavelengths (0.3–2.5 µm) with an average reflectance of 0.93. A thin (≈ 50 nm) Ag back‑reflector prevents transmission losses. The ~70 % increase in net cooling power
