Abstract

Memristor The cover illustrates a volatile memristor as an artificial nociceptor that links external stimulation with neuromorphic signal processing. Interactive thermal–mechanical stimuli are encoded into dynamic electrical responses through threshold switching, relaxation, and temperature-dependent sensitivity. By emulating biological pain perception, the device provides a biomimetic sensory platform for intelligent e-skin, human–machine interfaces, and neuromorphic robotics. More details can be found in the Research Article by Hee-Dong Kim and co-workers (DOI: 10.1002/adfm.202528652).
