ACS Nano, Год журнала: 2024, Номер 18(16), С. 10818 - 10828

Опубликована: Апрель 10, 2024

Rapid advancements in immersive communications and artificial intelligence have created a pressing demand for high-performance tactile sensing gloves capable of delivering high sensitivity wide range. Unfortunately, existing fall short terms user comfort are ill-suited underwater applications. To address these limitations, we propose flexible hand gesture recognition glove (GRG) that contains micropillar sensors (MPTSs) inspired by the tube foot starfish. The as-prepared offer working range (5 Pa to 450 kPa), superfast response time (23 ms), reliable repeatability (∼10000 cycles), low limit detection. Furthermore, MPTSs waterproof, which makes them well-suited By integrating with machine learning algorithm, proposed GRG system achieves intelligent 16 gestures under water, significantly extends real-time effective communication capabilities divers. holds tremendous potential applications field communications.
