Precisely Timed On‐Demand Droplet Ejection and Collision in Free Space for Controlled Reaction Initiation

open access: yesSmall, EarlyView.
LiDIA is an on‐demand droplet‐in‐air platform that enables synchronized droplet collision, ultralow‐waste operation, and obstruction‐free sample delivery. By combining precise triggering with reliable free‐space dispensing, it provides a versatile route for rapid mixing and time‐resolved studies, with strong potential for applications in XFEL, cryo‐EM,

Reconciling Granular Hydrogel Microstructure and Mechanics via a Temporary Thermo‐Responsive and Cell‐Invadable Matrix

open access: yesSmall, EarlyView.
Thermo‐responsive granular hydrogels (TRGHs), composed of microparticles and an interstitial matrix, exhibit thermo‐responsive mechanical properties and allow cell infiltration. This system effectively addresses the conventional compromise between mechanical strength and porosity observed in granular hydrogels.

Dual‐Functionality, Bio‐Friendly Artificial Muscles for Actuation and Motion Sensing in Smart Wearable Systems

open access: yesSmall, EarlyView.
This work presents a biofriendly carbon nanotube yarn artificial muscle operating either as an in‐air unipolar actuator or as a self‐powered ionotronic strain sensor. Using a non‐volatile eutectogel‐derived electrolyte, the system achieves up to 2.9% contraction and 0.5 mV/% strain sensing sensitivity.

MO/PVDF‐HFP Electrospun Nanofiber‐Based Triboelectric Nanogenerator for Mechanical Energy Harvesting and Boundary Security Sensing

open access: yesSmall, EarlyView.
Magnesium oxide (MgO (MO)) nanoparticles (NPs) were synthesized via a hydrothermal process and MO/PVDF‐HFPnanofiber film‐based triboelectric nanogenerators (TENG) were fabricated by incorporating various concentrations of MO NPs into the PVDF‐HFP polymer via the electrospinning process..

Robotic Palpation for Spatiotemporal Arterial Pulse Quantification and Mapping Using Multilevel Microdome‐Based Soft Pressure Sensors

open access: yesSmall, EarlyView.
This study presents the development of multilevel pressure‐sensitive layers replicated from liquid‐metal‐based structures for optimizing soft pressure sensors in robotic palpation. This approach enhances sensitivity and range for subtle arterial displacement detection.
