Answer: A system for recognizing human emotions
Notes: Scientists introduced PSiFI, a groundbreaking technology for real-time human emotion recognition. The personalized skin-integrated facial interface employs a unique bidirectional triboelectric strain and vibration sensor, enabling simultaneous sensing of verbal and non-verbal expressions. Self-powered and transparent, PSiFI employs machine learning algorithms for accurate emotion recognition, even with masked individuals. Demonstrated in a virtual reality concierge service, this friction charging-based system has potential applications in next-gen wearables, promising to revolutionize industries with emotion-based services.
