Non‐Invasive Multidimensional Capacitive Sensing for In Vivo Traumatic Brain Injury Monitoring

open access: yesAdvanced Materials Technologies, EarlyView.
Single‐electrode, multidimensional capacitive sensors noninvasively assess cerebral autoregulation and compliance for traumatic brain injury monitoring. ABSTRACT Traumatic brain injury (TBI) is a major cause of death and disability, but invasive intracranial pressure (ICP) monitoring is risky, and current non‐invasive methods lack the resolution and ...

Dynamic Current Routing in Conductive Liquid Crystal Elastomers for Complex Deformation Actuators

open access: yesAdvanced Materials Technologies, EarlyView.
This work introduces a novel actuation control strategy in which electrical stimulation generates localized Joule heating in conductive liquid crystal elastomer (LCE) surfaces, enabling complex 3D deformations from a single homogeneous surface without preprogramming.

Adhesive Double‐Network Granular Organogel E‐Skin

open access: yesAdvanced Materials Technologies, EarlyView.
We introduce a double‐network granular organogel adhesive for electronic skin, overcoming adhesion and strength trade‐offs. It provides reversible, robust bonding and ionic conductivity, enabling wearable and soft robotic e‐skin. Thanks to the e‐skin adhesive, a soft robotic trunk can recognize touch, temperature, humidity, and acidity.

Direct Laser Writing of Magnetic Micro Actuators With a Stimulus‐Responsive Compliant Hinge

open access: yesAdvanced Materials Technologies, EarlyView.
This study presents a versatile modular design strategy for adaptive 3D microactuators. Using two‐photon‐induced C,H insertion reactions within solid polymer layers, chemically distinct hinge and stimulus responsive materials are patterned in one step. The hinge's properties enable tunable motion, mechanical control, and reconfigurable actuation across

Optically Selective Photomask Based on Field‐Induced Periodic Defect Arrays in Ferroelectric Nematics

open access: yesAdvanced Optical Materials, EarlyView.
Field‐induced periodic defect patterns in the ferroelectric nematic liquid crystal phase act as optically selective photomasks. Created in the liquid crystal cells with bare electrodes, their periodicity is controlled by the applied frequency and cell gap. When used as photomasks, these patterns modulate transmitted light, whose spatial characteristics

The cone construction via intersection theory

open access: yes, 2019
We show a method in constructing algebraic cycles via intersection theory. It leads to a proof of the Lefschetz standard conjecture.
