Wearable Kirigami‐Apertured Capacitive Sensors for Continuous Cardiac Volumetric Monitoring

Advanced Functional Materials, EarlyView.
A wearable kirigami‐apertured carbon nanotube‐paper composite (K‐CPC) capacitive sensor enables cardiac volumetric monitoring. The kirigami process creates a central aperture with cantilevered fibers that confine the electric field, enhancing both sensitivity and lateral resolution.

Design and Characterization of a Two‐Dimensional Soft Array Based on Cooperative Dielectric Elastomer Actuators

Advanced Functional Materials, EarlyView.
A fully polymeric two‐dimensional array of Dielectric Elastomers enables self‐sensing, cooperative actuation, and large‐stroke operation in a DE‐based autonomous conveyor. Based only on voltage and current measurements at actuator level, the system detects the presence of a ball and subsequently drives it toward a target position.

Topological D-Class Physics with Passive Acoustic Elements

, 2022
In this work, we supply an engineering solution that paves the way to the implementation of the full classification table of topological insulators with passive acoustic crystals. As an example, we design an acoustic crystal displaying the full range of characteristics of a topological insulator from class D, such as non-trivial Chern numbers and an ...

Tailoring Light Management in All‐Perovskite Tandem Solar Cells: The Impact of Nanotextures

Advanced Functional Materials, EarlyView.
To further improve the power conversion efficiency of all‐perovskite tandem solar cells, light management strategies need to be implemented. Front‐sided nanotextures reduce reflection losses, which boosts light absorption, thus increasing the tandem JSC, which is further supported by reducing parasitic absorption.
