Flexible Hybrid Coatings for Applications in Thermoelectric and Piezoelectric Generators (TPEG)

Conventional thermoelectric and piezoelectric paints and coatings face significant limitations, including low efficiency, poor adhesion, limited durability, and manufacturing complexity, which hinder their performance in demanding environments. Additionally, the inherent fragility of ceramic substrates restricts their use on curved or irregular surfaces, posing challenges in adapting to high-temperature hotspots common in advanced munitions.To overcome these obstacles, innovative approaches are required to enhance the conformality and performance of advanced thermoelectric coatings on metallic structures in ordnance, enabling efficient thermal energy harvesting in versatile applications.IBC’s Plasma Electrolytic Oxidation (PEO) coating technology introduces a robust nanoceramic oxide interface layer, improving the compatibility between metallic substrates and advanced organic or inorganic thermoelectric layers. Moreover, the synergistic coupling of thermoelectric and piezoelectric generation (TPEG) can achieve up to a 400% increase in power output compared to standalone thermal or piezoelectric systems.
