An Assisting Contact Electrification Strategy for Achieving Self‐Recoverable Mechanoluminescence

Advanced Science, EarlyView.
ABSTRACT Self‐recoverable mechanoluminescence (ML) is a unique property of materials that can stably emit light under repeated stress, enabling new applications in smart sensing, displays, and wearable devices. However, self‐recoverable ML is very rare and only observed in a few active phosphors excited by piezoelectricity or contact electrification ...

A nematic liquid crystal elastomer rotary engine

Scientific Reports
Abstract Nematic liquid crystal elastomers (NLCEs) could perform as soft actuators because they generate greater contraction stress than ordinary rubber in response to a temperature rise of several tens of Kelvin. In this study, we follow the Wiegand rubber motor design, and develop a prototype star-shaped type rotary engine with four

Liquid crystal elastomers as machines [PDF]

, 2017
Liquid crystal elastomers (LCEs) are rubber-like solids that spontaneously deform under stimuli such as a temperature change, light and electric field. The nature of the spontaneous deformation can be controlled in nematic genesis LCEs by controlling the

Emergent Spinning and Orbital Motion in Clustered Wind‐Assisted Flyers

Advanced Science, EarlyView.
Inspired by natural snowflake geometries, paper‐cut flyers exhibit geometry‐defined spinning and orbital motions during cluster formation in a wind tunnel. Collective flights of multiple paperflakes reveal dynamic clustering, fragmentation, and continuously evolving spin behaviors.
