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

open access: yesAdvanced 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.

Bioinspired Adaptive Artificial Cilia With Tunable Sensitivity and Dynamic Range for Airflow Monitoring in the Central Airway

open access: yesAdvanced Materials Technologies, EarlyView.
A magnetically reconfigurable airflow sensor integrated with an airway stent enables tunable sensitivity and dynamic sensing range. Airflow‐induced cantilever deformation generates resistance changes, while an external magnetic field modulates sensor stiffness, enhancing sensitivity at low airflow velocities and extending the sensing range at higher ...

A Critical Time Window of Neocortex Modulation for Remote Fear Memory in Rats and Humans

open access: yesAdvanced Science, EarlyView.
This study identifies a delayed consolidation window around 18 h after fear learning in the mPFC essential for remote fear memory. VTA dopaminergic input during this window sustains remote memory in rats, while non‐invasive stimulation of homologous human mPFC at the corresponding time selectively weakens remote but not recent fear memory, revealing a ...
