Chemically Doped Conductive Polymers for Wearable Health Monitoring

Advanced Materials Technologies, EarlyView.
Among conductive polymers, poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), polyaniline (PANI), and polypyrrole (PPy) are the most studied and applied. Chemical doping significantly boosts intrinsic conductivity and mechanical robustness.

Passive Shape‐Adaptive Fluidic Interface for Enhanced Skin‐Sensor Coupling in Wearable Devices

Advanced Materials Technologies, EarlyView.
This study presents a passive fluidic interface for wearable biosensors that adapts to static and dynamic body shape changes to maintain consistent skin contact. Flexible, fluid‐filled pouches redistribute pressure from high‐load areas to regions requiring improved contact, enhancing signal quality and comfort in a compact, low‐energy design for ...

Electrical Control of the Transduction Channels’ Gating Force in Mechanosensory Hair Cells

Advanced Science, EarlyView.
The inner ear's hair cells rely on mechanosensitive ion channels to convert vibrations of their hair‐bundle into electrical signals. We show that varying the electrical potential (U) across the sensory epithelium modulates a key determinant of mechanosensitivity—the gating force (FG)—by modulating the gating swing (d), ranging from the size of the ...
