Stretching the future: Role of elastomers in sensor innovations

Flexible sensors offer several advantages, particularly in the emerging realm of wearable electronics, including adaptability to irregular surfaces, light weight, and conformability. Among the various flexible substrates suitable for fabricating sensors, elastomers stand out as convincing choices, owing to their capacity to uphold mechanical integrity while possessing soft and compliant characteristics. This review summarizes and discusses different types and advancements in wearable flexible sensors fabricated of elastomers, especially emphasising piezoresistive, self-healing, capacitive, piezoelectric, triboelectric, temperature, humidity, electrochemical, and ionic sensors. A comparative analysis of studies on flexible sensors reported in this review highlights key factors such as the materials used, sensor type, durability, response time, sensitivity, gauge factor and application suitability. Finally, future perspectives are also included in this review, focusing on the challenges in devising wearable sensors with high sensitivity and exploring the potential of assimilating artificial intelligence and IoT into wearable sensor fabrication. The review concludes that the ongoing advancements in emerging materials, innovative manufacturing methods, intelligent sensing technologies, artificial intelligence, the Internet of Things (IoT), edge computing, and neuromorphic computing are poised to amplify the performance and capabilities of flexible sensors. This review promises to enlighten the readers on the merits of flexible sensors over rigid ones and the advantages of elastomers over other substrates in fabricating flexible wearables. The readers will gain an understanding of the basic mechanism of operation of different flexible sensors and be made aware of the relevant applications of elastomeric sensors in detail. In addition, they will gather insights on the challenges and the future outlook in the realm of elastomeric wearables.
