Plastic electronics is soft, deformable and lightweight and it is suitable for the realization of devices which can form an intimate interface with the body, be implanted or integrated into textile for wearable and biomedical applications. Here, we present flexible electronics based on amorphous oxide semiconductors (a-IGZO) whose performance can achieve MHz frequency even when bent around hair. We...
TFTs on flexible plastic foils have the potential to enable new applications like electronic skins or smart textiles. Due to the temperature sensitivity of plastic substrates, amorphous In-Ga-Zn-O (a-IGZO) is a promising semiconductor since it provides a carrier mobility >10 cm2/Vs when deposited at room temperature. Therefore, a-IGZO TFTs have significantly increased electrical performance compared...
Findings obtained from bending experiments with mechanically flexible InGaZnO-based thin-film transistors are used to derive design rules for flexible InGaZnO-based n-channel metal–oxide–semiconductor logic circuits. Based on the developed design rules, flexible nand gates, inverters, and five-stage ring oscillators are fabricated directly on free-standing plastic foils at temperatures ...
