Advocating for the voices of disabled, particularly through wearable artificial throats, has garnered significant attention recently. Such devices necessitate sensors with stretchability, high sensitivity, and excellent skin conformability. In this study, an intelligent photonic throat been developed. It features a sandwich-structured optical fiber sensor encapsulated in Dragon Skin 20, which elastic modulus similar to human tissue is integrated sensitivity-enhancing rings fabric enhanced wearability. With ultrafast response (response time: 10 ms, recovery 32 ms) sensitivity (1.92 μW/mN), it detects area vibrations muscle contractions, accurately identifying tones Mandarin, vowels, words, sentences English, achieving accurate bilingual detection. also distinguishes animal sounds (horse neighing cuckoo's call) pop songs when mounted on speakers. Furthermore, can detect subtle movements head neck, by combining nodding actions MORSE code, silent communication between individuals successfully achieved. Integrated advanced intelligence (AI) algorithm, recognizes (97.50%), vowel letters (97.00%), common words (98.00%) (96.52%), opening prospects biomedical applications, language education, speech recognition, motion monitoring, more.

The rapid development of flexible sensor technology has made arrays a key research area in various applications due to their exceptional flexibility, wearability, and large-area-sensing capabilities. These can precisely monitor physical parameters like pressure strain complex environments, making them highly beneficial for sectors such as smart wearables, robotic tactile sensing, health monitoring, electronics. This paper reviews the fabrication processes, operational principles, common materials used sensors, explores application different materials, outlines two conventional preparation methods. It also presents real-world examples large-area arrays. Fabrication techniques include 3D printing, screen laser etching, magnetron sputtering, molding, each influencing performance ways. Flexible sensors typically operate based on resistive capacitive mechanisms, with structural designs (e.g., sandwich fork-finger) affecting integration, recovery, processing complexity. careful selection materials—especially substrates, electrodes, sensing materials—is crucial efficacy. Despite significant progress design application, challenges remain, particularly mass production, wireless real-time data processing, long-term stability. To improve production feasibility, optimizing reducing material costs, incorporating automated lines are essential scalability defect reduction. For enhancing energy efficiency through low-power communication protocols addressing signal interference stability critical seamless operation. Real-time requires innovative solutions edge computing machine learning algorithms, ensuring low-latency, high-accuracy interpretation while preserving flexibility Finally, environmental adaptability demands new protective coatings withstand harsh conditions. Ongoing overcoming these challenges, that meet needs diverse remaining cost-effective reliable.
