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.
