Volatile Memristive Devices With Tunable Temporal Dynamics For Event‐Based Sensing

Advanced Materials, EarlyView.
Tunable volatile memristive devices can serve various neural‐inspired tasks that require different time windows of information retention. The ionic‐based volatility of the presented Pt/a‐STO/TaOx/Ta device stack can be reproducibly and controllably tuned in multiple ways.

Bioengineered Interfaces for Peripheral Nerve Sensory Restoration

Advanced Materials, EarlyView.
Half of amputees abandon their prosthetics for lack of feeling. This review charts the full path from peripheral nerve injury to restored sensation, through surgical, regenerative, noninvasive, and implanted approaches, and shows how injury type and interface material properties determine which strategy can deliver naturalistic feedback, and why ...

Wavelength‐ and Helicity‐Reconfigurable Circularly Polarized Optical Diodes Enabled by Molecular Photoswitches

Advanced Materials, EarlyView.
All‐optical, photoswitchable diode‐type device for tunable nonreciprocal (asymmetric) transmission of CPL across a broad spectrum of light is demonstrated using molecular motor (photoswitch)‐doped cholesteric liquid crystals (CLCs) sandwiched between polyvinyl alcohol (PVA) and polydopamine (PDA)‐PVA composite layers.
