AI enabled sign language recognition and VR space bidirectional communication using triboelectric smart glove

Nature Communications, Journal Year: 2021, Volume and Issue: 12(1)

Published: Sept. 10, 2021

Sign language recognition, especially the sentence is of great significance for lowering communication barrier between hearing/speech impaired and non-signers. The general glove solutions, which are employed to detect motions our dexterous hands, only achieve recognizing discrete single gestures (i.e., numbers, letters, or words) instead sentences, far from satisfying meet signers' daily communication. Here, we propose an artificial intelligence enabled sign recognition system comprising sensing gloves, deep learning block, virtual reality interface. Non-segmentation segmentation assisted model achieves 50 words 20 sentences. Significantly, approach splits entire signals into word units. Then recognizes all elements reversely reconstructs Furthermore, new/never-seen sentences created by new-order recombination can be recognized with average correct rate 86.67%. Finally, results projected space translated text audio, allowing remote bidirectional signers

ACS Nano, Journal Year: 2021, Volume and Issue: 15(6), P. 9746 - 9758

Published: June 3, 2021

Flexible, breathable, and degradable pressure sensors with excellent sensing performance are drawing tremendous attention for various practical applications in wearable artificial skins, healthcare monitoring, intelligence due to their flexibility, breathability, lightweight, decreased electronic rubbish, environmentally friendly impact. However, traditional plastic or elastomer substrates impermeability, uncomfortableness, mechanical mismatches, nondegradability greatly restricted applications. Therefore, the fabrication of such high facile degradability, breathability is still a critical challenge highly desired. Herein, we present wearable, degradable, sensitive MXene/protein nanocomposites-based sensor. The fabricated MXene/protein-based sensor assembled from breathable conductive MXene coated silk fibroin nanofiber (MXene-SF) membrane patterned ink-printed (MXene ink-SF) interdigitated electrode, which can serve as layer electrode layer, respectively. exhibits wide range (up 39.3 kPa), sensitivity (298.4 kPa-1 1.4-15.7 kPa; 171.9 15.7-39.3 fast response/recovery time (7/16 ms), reliable cycling stability over 10 000 cycles, good biocompatibility, robust degradability. Furthermore, it shows great monitoring human psychological signals, acting an skin quantitative illustration distribution, wireless biomonitoring real time. Considering biodegradable features, may become promising find potential smart motion detection, disease diagnosis, human-machine interaction.
