발표초록 :
Atomic layer deposition (ALD) is a thin film deposition method employing self-saturated surface reactions in vacuum environments. Since ALD has several superior properties for nanoscale device fabrications, such as excellent conformality, large area uniformity, and process compatibility, over the conventional thin film deposition methods, it has been widely applied for various high technology applications from semiconductor to display devices. ALD can be an effect route to form materials with precise controllability in other applications. In this work, we extended ALD researches to fabrication of electronic textiles for wearable electronics. Inspired from the conventional dyeing technology, we coat normal textiles, such as cotton, with metal layers (Pt and Ru) through organic-inorganic hybridization in atomic level. The ALD-Pt-coated textiles showed high electrical conductivity and high mechanical durability even after mechanical wrinkling test and a real washing test. A capacitive type pressure sensor was fabricated by using the highly conductive yarn, and applied to seat sensor for vehicle. In addition, a textile-based heater was fabricated by the ALD E-textile. The E-textile system showed very high electrical power efficiency as a heater, and rapid heating up to 100 °C was achieved with just a 1.5 V AA battery. This textile-based heater system was integrated to artificial muscle platform for wearable mechanical suit systems.
