Advanced Materials Technologies, Journal Year: 2024, Volume and Issue: unknown

Published: Nov. 27, 2024

Abstract Flexible pressure sensors are unprecedentedly developed on monitoring human physical activities and human–computer interaction. Simultaneously, improving the sensitivity range of flexible is a great challenge. Despite introduction microstructures dielectric layer, deformability still limited due to size constraints microstructures, iontronic capacitive sensor (ICPS) difficult significantly improve. Here, an innovative strategy combining nano‐ZnO sodium alginate (SA) ionogels with two‐stage enhancement (TSE) structures, which can enhance toughness ICPS for ultrasensitive range, proposed. Compared other previously reported sensors, in this work exhibits ultra‐high (S max >17000 kPa −1 , S min >360 ) broad sensing more than 900 maintains stable long‐term working durability 4000 cycles. The demonstrates its versatility potential practical applications activity This provides general achieve broader pressure‐response higher sensitivity, offering effective way low‐cost, scalable sensor.
