用于柔性交互界面的木质触觉传感器设计OA

Developing flexible tactile sensors that combine environmental friendliness,unique aesthetic tactile quali-ties,and high performance is crucial for advancing sustainable human-computer interaction technologies.This paper presents a new strategy for fabricating flexible tactile sensors based on natural wood.The method begins with the deligni-fication and hemicellulose removal of natural wood to obtain a flexible,transparent wood template that retains its micro-porous structure.Subsequently,polypyrrole is uniformly loaded inside the template via in-situ polymerization,and pat-terning is achieved using conductive silver paste to create a sandwich-structured sensor.This sensor not only preserves the tactile and mechanical flexibility of the wood but also enables high-precision pressure sensing,providing a reliable so-lution for flexible tactile interactive interfaces.The performance evaluation results indicate that the wood-based flexible sensor can stably perform preliminary data processing through its intrinsic nonlinear dynamic response under different pressures ranging from 2 kPa to 10 kPa.Furthermore,this study highlights its potential applications in interactive inter-faces and wearable devices.The proposed scalable and efficient wood functionalization strategy offers a flexible,high-performance,and environmentally friendly tactile sensing solution.It also paves the way for the design of interactive sys-tems that balance material sustainability,aesthetic value,and tactile functionality.
