Fibrous Pressure Sensor with Unique Resistance Increase under Partial Compression: Coaxial Wet‐Spun TiO2/Graphene/Thermoplastic Polyurethane Multi‐Wall Multifunctional Fiber

open access: yesAdvanced Materials, EarlyView.
TGTMW fibers are designed to show a sharp resistance increase under pressure, as the multi‐wall structure in the transition region between compressed and uncompressed areas bends and forms microcracks. This design breaks the physical sensitivity limit of conventional fiber‐shaped pressure sensors, which usually show resistance reduction under pressure ...

DEP-on-a-Chip: Dielectrophoresis Applied to Microfluidic Platforms

open access: yesMicromachines, 2019
Dielectric particles in a non-uniform electric field are subject to a force caused by a phenomenon called dielectrophoresis (DEP). DEP is a commonly used technique in microfluidics for particle or cell separation.

Spatial Control of Chiral Self‐Assembly and Lithographic Applications in Liquid Crystal Polymer Network

open access: yesAdvanced Materials, EarlyView.
This work demonstrates a strategy to spatially control supramolecular chirality by leveraging spontaneous twist self‐assembly in liquid crystal materials. It is generated by periodic zigzag line defects that define alternating enantiomeric domains, stabilized by a polymer network. This approach enables precise defect engineering, tunable chirality, and

Polystyrene Nanoplastic‐Mercury Complexes Detection by Electrolyte‐Gated Carbon Nanotube Field‐Effect Transistor‐Based Sensors

open access: yesAdvanced Materials Interfaces, EarlyView.
An electrolyte‐gated field effect transistor sensor is used to detect an environmentally relevant nanoplastic model. The sensor identifies the presence of polystyrene nanoplastics in water dispersions without significantly altering its performance in the presence of mercury on the nanoplastics’ surface, indicating that it may be utilized in ...
