Light‐Driven Control of Polar Order in Ferroelectric Nematic Liquid Crystals

Angewandte Chemie, EarlyView.
Light‐responsive ferroelectric nematics are achieved by molecularly matching azobenzene photo‐switches to the polar packing motif of DIO. This design yields intrinsically photo‐responsive ferroelectric nematic mesogens and optically addressable DIO blends, in which light reversibly modulates spontaneous polarization and switches between high‐ and low ...

Tuning Local Modulus at Liquid Metal‐Polymer Interfaces Regulates Electrocaloric Effect in Ferroelectric Nanocomposites

Advanced Electronic Materials, EarlyView.
Liquid metal nanoparticles create mechanically compliant polymer interfaces that facilitate reversible dipolar reorientation under electric fields, whereas rigid interfaces impose stronger local constraints. This soft–rigid interface comparison reveals local interfacial modulus as a key parameter for tuning electrocaloric entropy change in ...

p‐Block Catecholates: A Century‐Old Platform for Hybrid Molecular Ferroelectrics

Angewandte Chemie, EarlyView.
Ferroelectricity in the p‐block catecholato complex [Et4N][Cl‐Ge(cat)2] is demonstrated through polarization and piezoelectric measurements on thin films. Density functional theory calculations reveal the spontaneous polarization arising from the transition between centrosymmetric and polar structures, establishing p‐block catecholato complexes as a ...

Direct Electrocaloric Characterization of Polyvinylidene Fluoride‐Based Co‐ and Terpolymers Over a Wide Temperature Range

Advanced Electronic Materials, EarlyView.
A systematic study of polyvinylidene fluoride‐based copolymers and terpolymers over a broad temperature range shows that commercially available polymers can compete with the best electrocaloric ceramics, exhibiting a large electrocaloric effect of ∼4.5 K in several compositions.

Polymer stabilized electrically suppressed helix ferroelectric liquid crystal

, 2014
A polymer stabilized ferroelectric liquid crystal (FLC) is introduced. With the expose of UV light, the doped monomer formed a polymer network and thus stabilize the FLC working in electrically suppressed helix mode.

Exploiting Ferroelectric and Spintronic Dynamics for Neural Network Computation

Advanced Intelligent Systems, EarlyView.
Ferroelectric and spintronic devices, relying on the control of polarization and magnetization, offer intrinsically fast, durable, energy‐efficient, and low‐latency building blocks for analog in‐memory computing. The hysteretic dynamics of an order parameter are leveraged to provide nonvolatile, multistate memory and nonlinear switching. Brain‐inspired

Biomimetic 3D Tactile Sensor System With Neuromorphic Encoding for Fascicle‐Level Feedback

Advanced Intelligent Systems, EarlyView.
A 3D biomimetic tactile sensor system converts skin‐like mechanical interactions into neural stimulation‐ready spike patterns. Embedded slow‐ and fast‐adapting sensors distinguish sustained pressure from transient touch, while neuromorphic encoding preserves their temporal signatures.
