Bamboo-Inspired, Environmental Friendly PDMS/Plant Fiber Composites-Based Capacitive Flexible Pressure Sensors by Origami for Human–Machine Interaction

ACS Sustainable Chemistry & Engineering, Journal Year: 2024, Volume and Issue: 12(12), P. 4835 - 4845

Published: March 8, 2024

With the widespread adoption of green and sustainable development concepts, enhancing sensing performance flexible pressure sensors while reducing manufacturing costs environmental pollution has emerged as a pressing research issue. Drawing inspiration from bamboo, naturally occurring plant, we utilized virgin bamboo pulp raw material for producing draw paper. The resulting cylinder structure serves dielectric layer. We propose an extremely low-cost, user-friendly, origami method fabricating paper-based sensors. structural parameters sensor were thoroughly investigated optimized through finite element simulations practical experiments. Notable features include high sensitivity (1.96 kPa–1 within 0–50 kPa), low detection limit (2 Pa), wide range (0–500 rapid response recovery times (40 45 ms, respectively), reliable durability stability (∼5000 cycles). Experimental results demonstrate successful application these in areas such human motion, health monitoring, human–computer interaction. potential applications extend to wearables, smart healthcare, human–machine collaboration, electronic skin (e-skin).

Bending and Stretching‐Insensitive, Crosstalk‐Free, Flexible Pressure Sensor Arrays for Human‐Machine Interactions

Advanced Materials Technologies, Journal Year: 2024, Volume and Issue: 9(5)

Published: Jan. 10, 2024

Abstract Accurate data acquisition from flexible sensors placed on deformable 3D freeform surfaces is of critical importance for many applications, such as wearable electronics, human‐machine interfaces, and soft robotics. However, the mechanical coupling between sensor subject surface to bending stretching deformations can significantly reduce accuracy acquired data. This study combines a polyimide (PI) micropore isolation layer (PIL) serpentine electrodes with piezoresistive mitigate issue coupling. As buffer distribute external pressure strain concentration, PIL avoid interference curvature up 256 m −1 , while maintaining high sensitivity S > 21.5 kPa . The electrode design further allows reliably acquire in presence 45% without cross‐talk. versatility developed demonstrated several interaction scenarios, including gesture recognition motion detection. strategies materials structures this also be applied development other low deformation surface.
