A Hydrophilic Hollow Microneedle Platform for Sampling Interstitial Fluid and On‐Site Biomarker Detection

open access: yesAdvanced Materials Technologies, EarlyView.
This study presents a superhydrophilic 3D‐printed hollow microneedle patch for continuous interstitial fluid (ISF) extraction and on‐patch biomarker sensing. Combining projection micro‐stereolithography and chemical vapor deposition, high‐resolution microneedles with enhanced wettability are fabricated, enabling passive ISF uptake without external ...

Event‐Driven Elongation Monitor for Soft Devices Using a Deformation‐Activated Piezoconductive Switch

open access: yesAdvanced Materials Technologies, EarlyView.
A stretchable, event‐driven strain sensor with low energy consumption is developed using positive piezoconductive composites. These composites remain insulative when relaxed, while they become conductive when stretched. Their electrical characteristics are modifiable by the nickel's weight ratio and cross‐sectional geometry. Strain‐induced switching is
