Hydrogel‐Based 3D‐Printable Stretchable Pressure Sensor

open access: yesAdvanced Materials Technologies, EarlyView.
We present a carbon‐black‐functionalized double‐network granular hydrogel (DNGH) pressure sensor capable of detecting pressures from 200 Pa, equivalent to a light finger touch, up to 500 kPa. The sensor exhibits signal drifts below 3.5% after 800 cycles and response times around 80 ms. Leveraging this broad sensing range, we 3D print this material into

Flexible, Integrated‐Porous Microneedle Sensor for Biofluid Sampling and On‐Site Biomarker Detection

open access: yesAdvanced Materials Technologies, EarlyView.
A paper‐integrated porous PGA microneedle array patch capable of both high strength and absorption capacity is proposed. With an image‐processing system, an optimized colorimetric sensor achieves a low limit of detection of 0.09 mm in cholesterol.

Wrinkling criteria in sheet metal forming for single sided contact situation and its application [PDF]

open access: yes, 2005
The general wrinkling theory based on the rate formulation of the principle of virtual work has been applied in a number of studies on wrinkling during sheet metal forming. No contact with the die was allowed.

Fully Inkjet‐Printed Organic Electrochemical Transistors: A Path Toward All‐Organic Electronics

open access: yesAdvanced Materials Technologies, EarlyView.
Fully printed organic electrochemical transistors eliminate the metal electrodes used in conventional printed organic electronics. This work demonstrates the state of the art in three applications using PBFDO and PEDOT:PSS materials: a single‐material strain sensor for real‐time detection of finger flexion, an ion sensor for monitoring aqueous NaCl ...

Inverse form finding with h-adaptivity and an application to a notch stamping process [PDF]

open access: yes, 2017
The aim is to determine the optimized semi-finished workpiece geometry to its given target geometry after a forming process. Hereby, a novel approach for inverse form finding, a type of a shape optimization, is applied to a notch stamping process.

Photothermomechanically Efficient, Low‐Cost, High‐Cycle‐Life, Hybrid MXene‐Polymer Actuators

open access: yesAdvanced Materials Technologies, EarlyView.
The addition of MXenes to elastomer‐plastic‐paper films enables the creation of easily prepared actuators that are scalable for small robotic applications. Known as MXene‐polymer Trilayer Actuators (MPTAs), they bend from UV light. Their usefulness is demonstrated through kirigami‐inspired flower‐shaped art design, parallel manipulator for waveguiding,

The mechanics of incremental sheet forming

open access: yes, 2017
Incremental sheet forming (ISF) is a flexible process where an indenter moves over the surface of a sheet of metal to form a 3D shell incrementally by a progression of localised deformation. Despite extensive research into the process, the deformation mechanics is not fully understood. This thesis presents new insights into the mechanics of ISF applied

Millisecond‐Switching Dual‐Band/Dual‐Polarization Ka‐Band Wavefront Control Enabled by a Complementary Liquid‐Crystal Metasurface

open access: yesAdvanced Materials Technologies, EarlyView.
An LCD‐compatible complementary liquid‐crystal metasurface delivers dual‐band, dual‐polarized Ka‐band wavefront control with millisecond switching via a 10‐µm LC gap. Interlaced patch/slot pairs enable independent phase tuning at 28 and 38 GHz, while strategic 45° slot rotation suppresses parasitic resonances. Measurements on a 160 × 160‐cell prototype
