Deep Eutectic Solvent‐Enhanced PEDOT: PSS/NR Foam Piezoresistive Sensor for High‐Sensitivity Wearable Devices and Sleep Monitoring Applications

Advanced Materials Interfaces, EarlyView.
A high‐performance piezoresistive foam sensor is developed by integrating natural rubber, PEDOT: PSS, and a deep eutectic solvent (DES). DES effectively detaches insulating PSS from PEDOT, dramatically amplifying electrical conductivity and sensitivity.

Low-Cost Impedance Analyzer for Electromechanical Impedance Technique In Wireless Sensor Networks

Wireless Sensor Networks (WSNs) enable dense, distributed, and 'deploy-and-forget' Structural Health Monitoring (SHM) systems, reducing the need for costly and labor-intensive manual measurements. However, reliable sensing is essential before deploying WSNs in critical infrastructure to ensure accurate and trustworthy data. Electro-mechanical impedance

Hierarchical Multi‐Material Architectures With Gradient Design for Dynamic‐Range Flexible Tactile Sensing

Advanced Materials Technologies, EarlyView.
Hierarchical multi‐material TPMS lattices are engineered as flexible tactile sensors by combining soft and stiff elastomeric layers with a conformal conductive coating. The bilayer architecture delivers sensitivity at low pressures while maintaining a broad detectable range under large loads, enabling reliable pressure and vibration monitoring for ...
