Flexible, semitransparent ionic liquid gel (ionogels) film was first fabricated by in situ polymerization. The optimized ionogels exhibited excellent mechanical properties, high conductivity, and force sensing characteristics. The multifunctional sensor based on the ionogel film was constructed and provided the high sensitivity of 15.4 kPa^–1 and wide detection range sensing from 5 Pa to 5 kPa. Moreover, the aforementioned sensor demonstrated excellent mechanical stability against repeated external deformations (for 3000 cycles under 90° bending). Importantly, the sensor showed advantages in detection of environmental changes to the external stimulus of subtle signals, including a rubber blower blowing the sensor, gently touching, torsion, and bending.

基于离子液体凝胶膜的柔性高灵敏压力传感器

首先通过原位聚合制备柔性的半透明离子液体凝胶（离子凝胶）薄膜。经过优化的离子胶具有出色的机械性能，高电导率和力感测特性。构建了基于离子凝胶膜的多功能传感器，并提供了15.4 kPa ^–1的高灵敏度和5 Pa至5 kPa的宽检测范围。此外，上述传感器表现出优异的机械稳定性，可抵抗反复的外部变形（在90°弯曲下进行3000次循环）。重要的是，该传感器在检测环境变化对微妙信号的外部刺激方面表现出优势，包括橡皮鼓风机吹传感器，轻轻触摸，扭转和弯曲。
