Synergistic Structural Construction of Strain Sensors with Low Baseline Drift and High Sensitivity for Continuous Dynamic Monitoring

Nano Letters, Год журнала: 2025, Номер unknown

Опубликована: Март 17, 2025

Strain sensors based on conductive elastomers face challenges like baseline drift and noise due to inherent viscoelasticity weak electrode interfaces under dynamic strains. Herein, a synergistic structure with biphasic hierarchical networks stable is proposed address these issues. The sensor employs multilayer polydimethylsiloxane (PDMS) substrate, carbon nanotube-doped PDMS (CNT-PDMS), Ag film. Electrodes are fixed using rigid island reinforced mortise tenon joint formed CNT-PDMS. film dominates resistance during release, significantly reducing drift. Strain-insensitive further reduce noise. This optimized design ensures 99.999% recovery without delay, even at high-speed (800 mm/min) large (80%) exhibits high gauge factor of 55442, low detection limit (0.02%), excellent stability (5000 cycles). With the designed algorithms, single-channel achieves 98.2% decoding accuracy for various gestures, demonstrating great potential wearable electronics.

Mechanically Robust and Ultrasensitive Natural Rubber/PEDOT:PSS Foam for Piezoresistive Sensors and Motion Monitoring

ACS Applied Electronic Materials, Год журнала: 2025, Номер 7(1), С. 313 - 321

Опубликована: Янв. 3, 2025

The development of low-cost and high-performance flexible polymer-based piezoresistive sensors is great significance in the fields human–machine interaction, motion monitoring, wearable technologies. However, traditional are generally prepared by immersion spray-coating conductive fillers on polymer foams, easy to fall off from framework under external stress, which makes it difficult for sensor meet long-term use requirements. In this paper, a stable foam was fabricated cofoaming natural latex poly(3,4-ethylenedioxythiophene) (PEDOT):poly(styrenesulfonate) (PSS) fabricate NR/PEDOT:PSS foam. PEDOT can be uniformly distributed NR latex. PSS with emulsification feature also introduces secondary pore This as-prepared hierarchical porous structure has merits fabrication, robust mechanical properties, excellent flexibility, good reproducibility (1000 cycles), durability. Additionally, exhibits wide sensing range, fast response (140 ms), recovery time (120 ms). These advantages enable effectively differentiate between movements different joints various behaviors. Furthermore, provide capabilities gait monitoring warning. Overall, demonstrates significant potential applications electronics.

Опубликована: Ноя. 4, 2024

Abstract 1D yarn sensors, crucial for smart textiles, face challenges in achieving diverse functionalities, multiple applications, and durability harsh environments. Herein, a simple strategy is proposed to prepare reduced graphene oxide‐polyimide yarns (rGO‐PYs), constructing functional multi‐dimensional sensors multi‐scenario applications. rGO‐PYs can detect mechanical stimuli, exhibit broad bending pressure response range (0°–180° 0.12–62.39 KPa), quick recovery time (both <100 ms), excellent cyclic stability. It features real‐time monitoring of human activities, such as joint movements, speech, writing, respiratory, pulse, heart rate. remarkable resilience environments, whether liquid nitrogen (−196 °C), high temperature (300 acid, or base. Crucially, expanded into an integrated 2D fabric, maintain their exceptional sensing. The point contact sensor (PCPS) sensing array showed performance identifying its distribution.
