Ultrasoft Iontronics: Stretchable Diodes Enabled by Ionically Conductive Bottlebrush Elastomers

Advanced Functional Materials, EarlyView.
This work introduces a solvent‐free, ultrasoft, and stretchable ionic diode based on oppositely charged bottlebrush elastomers (BBEs). The BBE diode exhibits an ultralow Young's modulus (<23 kPa), a high rectification ratio of 46, and stretchability over 400%.

Skeletal muscle performance and ageing

Journal of Cachexia, Sarcopenia and Muscle, 2017
The world population is ageing rapidly. As society ages, the incidence of physical limitations is dramatically increasing, which reduces the quality of life and increases healthcare expenditures.

An Energetic Model of Muscle Contraction

Biophysical Journal, 1972
Initial energy utilization in the twitch is visualized as the result of the activity of two distinct processes. The first is the calcium-pumping activity of the sarcoplasmic reticulum, which has a constant energy requirement under normal conditions.

Magnetically Guided Mechanoactive Mineralization Scaffolds for Enhanced Bone Regeneration

Advanced Functional Materials, EarlyView.
A 3D‐printed ‘rebar‐concrete’ inspired scaffold (PGS‐P@MGel) synergizes spontaneous biomineralization with magneto‐mechanical stimulation through PDA@Fe3O4‐embedded hydrogel. This dual biointerface activates Piezo1/β‐catenin/YAP mechanotransduction axis, enhancing BMSCs osteogenesis and angiogenesis simultaneously.

Bioinspired Shape Reconfigurable, Printable, and Conductive “E‐Skin” Patch with Robust Antibacterial Properties for Human Health Sensing

Advanced Functional Materials, EarlyView.
In this article, Hojin Kim, Sayan Deb Dutta, and co‐workers report a shape‐reconfigurable, 3D printable, and highly adhesive slime‐like ‘electronic skin’ or ‘E‐skin’ patch for human health sensing and tissue engineering applications. The dual reinforcement of hydrogel patch with carbon nanotubes (CNTs) and cellulose nanocrystals (CNCs) improve the ...

Highly Sensitive Cuffless Blood Pressure Monitoring with Selective Laser‐Sintered Liquid Metal Conductors

Advanced Functional Materials, EarlyView.
A soft, compact, and cuffless system for continuous blood pressure monitoring using laser‐sintered liquid metal conductors is developed. The stretchability and sensitivity of the device enable real‐time, non‐invasive tracking of blood pressure, including recovery after exercise. This wearable device offers a practical solution for managing hypertension
