Electric-Ray-Inspired Universal Island-Bridge Structure for Transforming Nonpyroelectric Substrates into Pyroelectric Sensors

ACS Sensors, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 12, 2025

Large-area, flexible pyroelectric sensors have received increasing attention in a range of applications including electronic skin, robotics, and military. However, existing struggle to achieve both high performance excellent mechanical properties simultaneously. Here, we propose universal island-bridge percolation structure inspired by the electric organ ray that can enable nonpyroelectric substrates with generate effect. The network made particles (island) carboxyl-functionalized multiwalled carbon nanotubes (bridge) achieved transmission superposition effect through film polarization sensor based on not only inherits but also substrates. fabricated from polydimethylsiloxane (PDMS) exhibit good reliability even under 30% tensile rate 5,000 tensile-retraction cycles, those polyimide (PI) serve as skin for robots detect heat sources possess infrared sensing maximum distance 8 cm. This study provides ideas fabricate highly high-performance properties.

Polyvinyl alcohol (PVA) is a widely utilized molecular polymer characterized by its strong water solubility, chemical resistance, and mechanical properties. Notably, it possesses the capability for biodegradation finds extensive applications across various fields; thus, analyzing fundamental properties of PVA paramount importance. Materials scientists have shown considerable interest in modifying polymers such as PVA. Among modification techniques, microwave irradiation has garnered significant attention due to rapidity, efficiency, cost‐effectiveness. This study investigates effects temperature on binary solutions using Raman spectroscopy while also intermolecular hydrogen bonding within these solutions. The results indicate that increasing disrupts tetrahedral structure formed between water, leading transition toward chain‐like configuration; however, an enhancement partial occurs at 313.15 K. Furthermore, analysis solution post‐microwave reveals exposure microwaves enhances inducing depletion reaction after 180 s irradiation. Atomic force microscopy further demonstrates this duration leads pronounced chain stacking phenomena. paper substantiates serves effective method PVA, thereby offering robust strategy applicable materials science, chemistry, physics.
