Longitudinal Relationships of Subclinical Cardiovascular Disease with Physical Function in Older Adults [PDF]

open access: yes, 2009
Low ankle-arm index (AAI), a marker of peripheral arterial disease, predicts incident disability in older adults. Elevated pulse wave velocity (PWV), a measure of arterial stiffness, increases risk of cardiovascular events and mortality.

Design Principles for Deployable Fibers Inspired by Hagfish Defense

open access: yesAdvanced Science, EarlyView.
Hagfish slime deploys fibers from coiled skeins to form an ultra‐dilute, water‐trapping network. Inspired by this mechanism, design principles are established for synthetic skeins, fabricated with tightly coiled fibers that unravel under flow. These synthetic skeins demonstrate deployable fibrous networks, highlighting generalizable strategies for ...

A Super‐Capacitive Pressure Sensor with Ultrahigh Sensitivity and Wide Linear Pressure Sensing Range for Human Bio‐Signal Detection and Electronic Skin

open access: yesAdvanced Science, EarlyView.
Incorporating a PVA/H3PO4 ionic elastomer and a hierarchical hemisphere structure within the electrolyte layer, along with a curvy top electrode, enables the super‐capacitive pressure sensor to achieve ultrahigh sensitivity (34.79 nF kPa−1) and a broad linear sensing range (0–800 kPa).
