High‐Performance Ambipolar Organic Electrochemical Transistors Based on Diketopyrrolopyrrole‐Dialkoxybithiazole Conjugated Polymers for Single‐component Inverters

Advanced Science, EarlyView.
Two donor‐acceptor conjugated polymers, incorporating diketopyrrolopyrrole (DPP) and dialkoxybithiazole (2Tz) units with ethylene glycol (EG) side chains, exhibit relatively balanced ambipolar organic electrochemical transistor (OECT) performance. This ambipolarity enables the realization of single‐component complementary inverters capable of ternary ...

A Microfiber‐Reinforced Janus Hydrogel E‐Skin With Recyclable Feature for Multimodal Sensing and Gender‐Specific Physiological Monitoring

Advanced Science, EarlyView.
Hydrogel‐based wearable electronics hold great promise for physiological monitoring in privacy‐sensitive regions. In this study, a polyurethane (PU) microfiber‐reinforced gelatin hydrogel e‐skin is developed, boasting multiple advantages such as ultra‐thinness, high toughness, and long‐term skin conformability.

Electrode Engineering for High‐Durability Variable‐Emissivity Devices Based on Reversible Copper Electrodeposition

Advanced Science, EarlyView.
An Ir‐based reversible copper electrodeposition variable‐emissivity device achieved over 8000 cycles with just 11% radiative temperature variation decay. This stability stems from Ir's inherent inertness, high conductivity, and strength, which collectively suppress cracking and corrosion.

Record‐High Latent Heat, Ultra‐Fast Relaxation and Closed‐Loop Recycling Double‐Brush Polymer Networks for Self‐Adaptive Thermal Interface Management

Advanced Science, EarlyView.
By grafting dense long double‐brush chains, we synthesized bottlebrush networks with high theoretical enthalpy. Their low entanglement, combined with dynamic bonds, promotes crystalline domain reorganization and minimizes enthalpy loss, achieving a record enthalpy of 240.7 J·g−1.

Highly Sensitive and Temperature‐Insensitive Stretchable Strain Sensor with Microcrack‐Engineered Architecture

Advanced Science, EarlyView.
This study proposes a stretchable strain sensor that demonstrates a high gauge factor of 2.3 × 104 and excellent linearity (R2 = 0.98), while maintaining temperature insensitivity under applied strain. This performance is achieved through a microcrack architecture formed by stacking a brittle, low‐resistance material with a stretchable, high‐resistance
