Chemically Doped Conductive Polymers for Wearable Health Monitoring

open access: yesAdvanced 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.

Skin‐Like Tri‐Modal Sensors Based on Soft Piezoelectric and Ionic Composites

open access: yesAdvanced Materials Technologies, EarlyView.
Inspired by the multimodal perception of human skin, a soft, skin‐like tri‐modal sensor is presented. The device incorporates an ionically conductive, piezoelectric, elastic composite as its active layer, enabling independent detection of temperature, static strain, and dynamic strain within a single two‐terminal architecture.

Ultra‐Flexible Dual‐Band Organic Photodetectors for Visible and Near‐Infrared Sensing

open access: yesAdvanced Optical Materials, EarlyView.
An ultra‐flexible dual‐band organic photodetector with a total thickness of 5.6 µm for bio‐sensing is developed. It selectively detects visible and near‐infrared light with high sensitivity by switching the voltage. Peripheral oxygen saturation (SpO2) measurement is demonstrated using the device attached to a finger under a single light source by ...

Photochromic Diarylethene‐doped SU‐8 for Rewritable Optics and Integrated Photonic Switching

open access: yesAdvanced Optical Materials, EarlyView.
A CMOS‐compatible photochromic host–guest material platform is realized by incorporating diarylethene molecules into SU‐8 photoresist. Reversible photoisomerization enables light‐programmable optical absorption, allowing rewritable optical patterning and port‐selective attenuation in integrated waveguides.
